Description

 The composition relates to the field of oil production, in particular to compositions for the complex effect on produced fluids and is intended to simultaneously prevent the deposition of salts and asphalt-resin-paraffin substances (ASW) during the production of flooded oil from wells with both low and high reservoir pressure, as well as in the collection, transport and preparation of oil.

Currently, most of the known formulations are inhibitors of single-function action. Each of these inhibitors is introduced into the processed fluid stream separately:
- either they are pumped into the well (see, for example, "A method for preventing the deposition of inorganic salts using domestic-made polycomplexones (type PAF)" RD 39-1-217-79 and "Guidelines for the use of scale inhibitors based on hydroxyethylidene diphosphonic acid and polyethylene polyamine -N-methylphosphonic acid to prevent salt deposition "RD 39-23-702-82);
- either these inhibitors are introduced into the flow of produced or waste water (see, for example, RD 39-1-216-79 "Prevention of paraffin deposits in oilfield equipment)."

 However, these known compositions can be dissolved either only in oil, or only in water, and therefore, under conditions of constant changes in the ratio of oil to water during production over a long period, it is very difficult to provide reliable protection, even preventing one type of deposits (salt deposition or ASV) .

 In addition, most of the known compositions prevent only one type of sediment: either salt deposition or sedimentation deposits.

A known composition for influencing produced fluids with the following content of ingredients, wt.%:
scale inhibitor - 55.00-60.00
latex - 3.00-5.50
oil - 13.32-27.12
surface-active substances (surfactants) - 0.40-1.35
water - the rest
(see, for example, the USSR AS N 916523, M.C. 3 C 09 K 3/00, E 21 B 37/00, dated 06.11.79). In the specified known composition, a mixture of latex, oil, surfactant and water acts as a carrier substance. This known composition has a thick consistency and is delivered to the well using a perforated container.

 A method for preparing such a known composition for influencing produced fluids consists in first preparing a carrier substance by conventionally mixing the ingredients, then a scaling inhibitor is introduced into it gradually in three equal portions, after which the mixture is mixed and a known composition is obtained. The main disadvantage of this known composition with its manufacturing method is that it loses its effectiveness when the water content of reservoir fluids is more than 20%, because latex, which is part of the composition of this known composition, in contact with produced water coagulates and turns into a rubbery mass, which blocks the release of scaling inhibitor into the oil and water stream. In addition, the specified known composition can be dissolved only in oil. Along with this, this known composition is aimed only at preventing scaling, because It does not have multifunctionality.

 The closest in technological essence to the claimed composition for a complex effect on the produced fluids is a composition with the following ingredients, wt.%.

 Scale inhibitor oxyethylidene diphosphonic acid (HEDP) or nitrilotrimethylphosphonic acid (NTF ISB-1) 1.00-4.00.

 ACPV inhibitor of solid aggregative state (IPP-2 or IPP-3) 29.00-36.00.

 Corrosion inhibitor of solid aggregate state (IKB-4 or IKB-2 or IKB-6V) 12.00-18.00.

Carrier substance still residue of the production of primary amines C ₁₇ -C ₂₀ - the rest (see AS USSR N 1543052, M. Cl. E 21 B 37/06, C 09 K 3/00, C 23 11/00 from 10/03/08 g.).

 The composition is intended to prevent deposits of asphalt-resin-paraffin substances (ASPA), salts, and to prevent corrosion during the production of flooded oil. However, this composition is not effective enough to prevent deposits of ASW.

 As the studies showed, washing the oil film with the specified known composition is 80-90% in 60-180 seconds, and the amount of surface glossing in its presence reaches 20%, which does not allow sufficiently effective prevention of ASWA deposits.

 As laboratory studies and practice have shown, the use of a known composition during its self-dosage has revealed repeated emissions of large quantities of a phosphorus-containing component, which leads to its overuse and rapid leaching. This is accompanied by a reduction in the period of salt-free operation of wells. Most likely, this process can be explained by a small amount of a phosphorus-containing reagent in a known composition and, consequently, by an uneven distribution over its entire volume. In addition, this known composition contains ingredients that are currently not manufactured by domestic industry and are not manufactured abroad. These are solid inhibitors: ASPO-IPP-2 and IPP-3 and solid corrosion inhibitors: IKB-4, IKB-2, IKB-6V, i.e. the known composition is almost impossible to prepare and, therefore, to apply.

 The aim of the present invention is to increase the effectiveness of preventing the deposition of salts and ASAW in relation to light, medium, and especially heavy oils. In addition, the use of the inventive composition provides a long-term constant, in comparison with the known composition, the supply of inhibitory components in effective concentrations in the produced fluids at all possible ratios of oil and water. An additional goal, along with the prevention of paraffin, is the disposal of production waste and the use of ingredients produced by domestic industry for its production.

The stated technical problem is achieved in that the composition for the complex effect on the produced fluids, containing the phosphorus-containing reagent ISB-1 or HEDP and bottoms production of amines C ₁₇ -C ₂₀ , additionally contains a technical detergent of the FORS-1 type in the following ratio of components, wt. %:
phosphorus-containing reagent ISB-1 or OEDP - 12-80
FORS-1 technical detergent - 7-60
VAT residue of the production of amines C ₁₇ -C ₂₀ - the rest
Neither the patent nor the scientific and technical literature are we known compositions that inhibit the process of sedimentation and scaling, including these ingredients in the claimed quantitative ratio and allowing to solve the technical problem of the invention, which gives reason to conclude that the proposed composition has the criteria of "novelty "and" inventive step ".

 The achievement of the above technical result was made possible, apparently, due to the joint interaction of the ingredients included in the proposed composition.

VAT residues in the production of C ₁₇ -C ₂₀ amines play the role of a carrier substance. Due to its limited dissolution in produced fluids (oil and water), the phosphorus-containing reagent and TMS are released (self-dosed). Each of which works in the direction of its activity along the entire technological path of well production movement. The phosphorus-containing reagent (ISB-1 or HEDP) acts as a scale inhibitor, and TMS removes asphalt-resin-paraffin deposits (ARPD) formed during oil production, washing them off, then it envelops the fine crystalline ARPD structures and prevents them from sticking together and form large conglomerates. The resulting small-crystalline structures are in suspension, not precipitating, moving in the volume of well production along the entire production chain. Thus, TMS combine the functions of an ASD remover and inhibitor. If the above claimed composition for the complex effect on produced fluids is prepared according to the following proposed method, by which all the ingredients included in it are introduced with constant stirring in the following sequence: bottoms of the production of amines C ₁₇ -C ₂₀ (waste product), TMS and then phosphorus-containing reagent (ISB-1 or HEDP). Thus obtained solid composition resembling paraffin (soap) is divided into pieces, formed in the form of cylinders 15-20 cm long, 3-4 cm in diameter, and loaded into a container, which is then lowered into the perforation zone of production wells, as in the prototype by A.S. USSR N 1543052.

Formation fluids pass through openings on the side walls and at the end of the container, wash the cylinders of the composition for complex action obtained in the manner described above. Due to the gradual dissolution of the carrier substance - the bottom residue of the production of C ₁₇ -C ₂₀ amines (production waste) in the produced oil and water, the introduced phosphorus-containing reagent (ISB-1 or OEDF) and TMS (Force-1 type) are exposed, thereby achieving a constant , the necessary effective and sufficient concentration of phosphorus-containing reagent and TMS in the produced fluids.

To obtain the inventive composition for a comprehensive effect on produced fluids in laboratory conditions, the following substances were used:
- carrier substance - still bottoms in the production of amines C ₁₇ -C ₂₀ (production waste) TU 6-02-750-87, a burgundy-brown solid that resembles laundry soap in appearance;
- phosphorus-containing reagent: ISB-1 (NTF), manufactured by Cheboksary AO Khimprom according to TU 6-09-5283-86, a white crystalline substance, soluble in water;
- OEDP, a white crystalline powder, soluble in water, TU 6-09-20-54-79, manufactured by Cheboksary JSC "Khimprom";
- TMS:
Force-1, technical detergent, cream powder, manufactured in Perm, Pemos JSC, TU 2499-013-04643756-96;
SF-2U, cream powder, TU-10-RSFSR-465 is available in St. Petersburg;
LOTOS-pemos, universal, synthetic detergent, cream powder, manufactured in Perm, Pemos JSC, TU 2381-007-04643756-94.

To obtain the claimed composition carry out the following operations in the following sequence:
prepare a carrier substance - bottoms in the production of amines C ₁₇ -C ₂₀ (waste product). TMS and a phosphorus-containing reagent are introduced into the carrier substance sequentially, with constant stirring.

 The resulting composition is molded into cylinders, as previously indicated.

 The possibility of carrying out the claimed invention is confirmed by the following example.

 Example.

To obtain the claimed composition in laboratory conditions, 2.5 g of the carrier substance were taken, bottoms in the production of C ₁₇ -C ₂₀ amines, placed in a porcelain cup, heated in a water bath, then 3.5 g of TMS and 4 were introduced alternately with continuous stirring , 0 g of phosphorus-containing reagent. Then, after thorough mixing, the resulting composition was molded in the form of balls or cylinders. So we got the inventive composition, solid, reminiscent of laundry soap, with the following ratio of ingredients, wt.%: Phosphorus-containing reagent - 40; TMS - 35 and a carrier substance - bottom residue of the production of amines C ₁₇ -C _{20 the} rest is 25. Similarly, other compositions with different ratios of ingredients are obtained.

 We have carried out all the necessary laboratory tests.

The tests were designed to determine:
- the degree of dissolution of the carrier substance - the bottom residue of the production of amines C ₁₇ -C ₂₀ (waste product) in oil, produced water and mixtures thereof;
- the possibility of self-dosage of a phosphorus-containing reagent, which by its nature of its action is an inhibitor of scaling;
- the protective effect of the claimed composition for the prevention of ASA. The tests also aimed to establish the boundary and optimal values of the ingredients in the inventive composition obtained by the proposed method.

 Tests were carried out in the traditional way of determining the degree of dissolution of various substances. It is as follows. A weighed sample of the carrier substance (1 g) was placed in a conical flask with fluids taken in a volume of 1 l, the flask was closed with a stopper and installed in a device for shaking flasks. After 1 hour, the contents of the flask were filtered under vacuum through a blue ribbon filter. The carrier substance remaining on the filter was weighed. The amount of carrier substance of the claimed composition dissolved in 1 hour in various fluids is given in table. 1 (see tab. 1-7).

The data given in table. 1 show that the carrier substance (bottoms from the production of amines C ₁₇ -C ₂₀ ) in the claimed composition will dissolve simultaneously in oil and in water and in their mixtures, i.e. they will not prevent the simultaneous removal of the phosphorus-containing reagent and TMS from the claimed composition. Further, in the course of laboratory tests, the maximum optimal ratios of the ingredients in the proposed composition were determined.

 The choice of limit values of the ingredients in the claimed composition was due to the minimum concentration at which the maximum protective effect is achieved. When conducting these experiments used compositions, data on the contents of the ingredients in which are given in table. 2.

 The degree of leaching of phosphorus-containing reagents from the claimed composition was determined as follows.

The inventive composition was cut into pieces of 1-3 cm ³ in size, placed in glass cylinders with a diameter of 60 mm and a length of 300 mm with two taps: above and below. Then, through the funnel, the lower valve and pieces of the composition, waterlogged oil was fed into the cylinder, which was then collected through the upper valve into the receiver. Thus, the process of passing formation fluids through the claimed composition immersed in a cylinder (well) was simulated.

The carrier substance (distillation residues in the production of C ₁₇ -C ₂₀ amines), having limited solubility in the produced water and oil, provides access of the phosphorus-containing reagent and TMS to the liquid passing through them and those (phosphorus-containing reagent and TMS) show their inhibitory functions all the way movement. For the first time, 400 ml of oil and 600 ml of water were passed through a cylinder with the claimed composition, thus 60% of the water cut of wells was simulated. The passed fluid was in constant motion. Periodically, every hour, samples were taken of the liquid flowing out of the cylinder in a volume of 100 ml. In this case, the oil from the sample was separated in a separatory funnel, and the presence of a phosphorus-containing reagent (ISB or HEDP) was determined by phosphate ion in water. The effective concentration of the phosphorus-containing scaling inhibitor reagent (NTF (ISB-1)) is 2-5 mg / l (see RD 39-1-218-79 "Method for preventing the deposition of inorganic salts using organophosphorus compounds of domestic production such as ISB - Ufa, BashNIPIneft, 1979, p. 2) Determination of the content in water was carried out according to RD 39-1-237-79 "Determination of the content of deposition inhibitors of salts and organophosphorus chemicals in produced and fresh waters". Ufa, BashNIPIneft, 1979. This technique designed to determine the content the study of NTF ((ISB-1), OEDP, etc., organophosphorus compounds (esters, phosphonates, etc.) in produced, fresh waters.

To determine the quantitative content of salt deposition inhibitors in produced water, the analyzed water is first filtered (to remove solids and oil), then boiled (to remove hydrogen sulfide), a sample is taken (= 20 ml). It is brought to 100 ml with distilled water, quantitatively transferred to a conical flask, acidified with 1.5 ml of concentrated hydrochloric acid (GOST 14261-69), the flasks with solutions are placed on a preheated tile and brought to intense boiling. 7 ml of a 10% solution of chloramine "B" (OST 6-01-76-79) is added to the boiling solution and the test samples are boiled for 20 minutes (the volume of the samples should be reduced by boiling to 45-60 ml). Samples were cooled to room temperature and quantitatively transferred to 100 ml volumetric flasks. The volumes in the flasks were adjusted to 80-85 ml, 2 ml of a 5% ascorbic acid solution was added to them, everything was mixed, 5 ml of a specially prepared solution of ammonium molybdate was added, the volume in the flasks was adjusted to the mark with distilled water, and thoroughly mixed. In this case, staining of solutions from blue to blue is observed. After 5-10 minutes, the absorbance is determined on an FEK-56 (filter No. 9; λ = 680 mm, a cuvette with a layer thickness of 10 mm). Knowing the value of optical density, the content of the organophosphorus compound is determined from the calibration curve, the calculation of the content of inhibitor in water is carried out according to the formula:
P, mg / l = A • V ₁ / V ₂ ,
where A is the inhibitor content (mg / l) found by the calibration curve;
V ₁ - the volume to which the sample was diluted (100 ml);
V ₂ - the volume taken for analysis of water samples, ml.

 The preparation of a solution of ammonium molybdate is as follows.

144 ml of concentrated sulfuric acid are added to 300 ml of distilled water with stirring. The solution is cooled to 20 ^o C, 12.5 g of ammonium molybdate is dissolved in 200 ml of distilled water, heated to 80 ^o C. 0.235 g of antimony chloride is dissolved in a small amount of 20% hydrochloric acid and the volume is adjusted to 100 ml with distilled water. Solutions of ammonium molybdenum and antimony chloride are poured into a 1-liter volumetric flask; the volume is brought to the mark with distilled water. The ammonium molybdate solution thus prepared is stored in a dark glass bottle.

 Data on the content of the phosphorus-containing reagent in the samples of watered oil passed through the inventive composition are given in table. 3.

The data given in table. 3 show that the inventive composition for a complex effect on produced fluids containing the following ingredients, wt.%:
phosphorus-containing reagent (ISB-1 or OEDP) - 12-80
TMS (Force-1 type) - 7-60
VAT residue of the production of amines C ₁₇ -C ₂₀ (waste product) - the rest
provides a stable flow of phosphorus-containing reagent into the flow of reservoir fluids within its effective concentration.

 The indicated values of the ingredients are boundary, because their change to a greater or lesser extent does not allow to achieve the goal. So, for example, a composition containing 11% of a phosphorus-containing reagent, 70% - TMS and a carrier substance - the rest (experiments 17, 13, 19, 25, 31 of Table 3), has a low protective effect, because the output of the phosphorus-containing reagent, which is an inhibitor of the scaling process, into the oil stream is very small (below 2-5 mg / l), significantly lower than the value of its effective concentration. An increase in the quantitative values of the ingredients from the upper limit (experiments 5, 11, 17, 23, 29, 35 of Table 3) is not economically feasible, because the output of the phosphorus-containing reagent from the composition into the oil stream will be large and this will lead to its cost overrun.

The optimal composition will be as follows, wt.%:
phosphorus-containing reagent - 40
TMS - 35
VAT residue of the production of amines C ₁₇ -C ₂₀ (waste product) - the rest
Further, in the course of laboratory tests, the protective effect of the claimed composition was determined as an ASPO inhibitor. For research, the same oil and water were used, separated in a separatory funnel after passing them through pieces of the inventive composition.

 Determination of the inhibitory ability to prevent ARPD was carried out according to the generally accepted "Methodology for evaluating the effectiveness of paraffin scale inhibitors of complex and multiphase effect on washing a film of oil, dispersing and washing paraffin deposits with formation water". NPO Soyuzneftepromkhim. - Kazan, 1987

According to this methodology, the effectiveness of the claimed and known compounds for the prevention of paraffin is evaluated according to the following indicators:
1. For washing the film of oil with this composition.

 2. The value of the dispersion of paraffin in the medium of the claimed composition.

 3. According to the characteristics of the properties of dispersions under these conditions (sticking, coating of the surface).

 When testing the oil film for washing, the percentage of washing the oil film with formation water from the wall of the glass tube over time is determined (for 100% half of the entire surface of the tube is considered) without and in the presence of an inhibitor.

Accepted: excellent washing - 70-90% for 30 s;
good washing - 70-90% for 60 s;
satisfactory washing - more than 3 minutes, and in this case, a field test of the reagent is not recommended.

 In the dispersion test, the size of the obtained AFS particles in the formation water is determined by adding the test reagent.

The result is considered:
excellent if all AFS granules have a dispersion value of 0.1 to 3 mm (100%)
good - 0.1-5 mm (100%)
satisfactory - 0.17-7 mm (100%)
unsatisfactory over 7 mm
Upon receipt of the latter indicator, the reagent is not recommended for the field test.

 An illustration of the dispersion of paraffin in formation water with reagents are indicators of sticking and coating.

AFS deposits on the walls of a glass conical flask in% of the working surface:
the result is considered excellent if the sticks are 5%, good - up to 10%;
satisfactory - up to 40%; unsatisfactory - more than 40%.

 The reagent, in the presence of which, deposits of deposits above 40% are observed, is not recommended for a field test. Resin coating of the walls of the flask in the form of strips in% of the working surface. The result is considered to be excellent if the putty is not more than 5%; good - 20; satisfactory - up to 50%; unsatisfactory - more than 50%. The reagent giving the last result cannot be recommended for a field test.

 The definition of the first indicator - the degree of washing of the oil film was carried out as follows.

 20 ml of the test oil were poured into glass tubes and kept for 30 minutes to create an oil film on the surface of the tube. Then the oil was poured from the test tube and the formation water of the same field as the oil was poured into it in an amount of 10 ml and kept for 1 min. After that, 10 ml of oil passed through the inventive composition was added to the test tube. Test tubes were closed with stoppers and turned over.

 After 20 minutes, the surface of the tube, which was freed from the oil film in%, was visually determined. Similarly conducted a control experiment without a reagent. The effectiveness of the composition for washing the oil film was evaluated by the difference in the size of the surface freed from the oil film in this and control experiments.

 The determination of the size of dispersed particles of paraffin in the media passed through the inventive composition was carried out in the following sequence: 50 ml, produced water passed through the inventive composition was introduced into a conical flask. Next, ASPO sediments weighing 2.5 g were placed in the flask. The contents were heated on a tile until the deposits were completely melted. Then the flask was cooled under a stream of water, shook it in a circular motion. At the same time, the dispersion of paraffin deposits, adherence and coating of the walls of the conical flask were visually recorded.

 The data obtained during the studies are given in table. 4.

 The data table. 4 show that the effectiveness of the claimed composition is higher than the known efficiency.

So when researching the effectiveness of the known and claimed compositions on heavy oils of the Pavlovsk field (density 0.917 g / cm ³ ), the known composition washes off only 70% of the surface in 60 s, and the claimed composition launches an oil film almost completely (on 90% of the surface) for the same period . The size of the dispersion of particles of ASPA in the presence of a known composition reaches 0.1-5 mm, and in the presence of the claimed composition, all available ASPA have a dispersion of not more than 2 mm, which, of course, contributes to their better retention in the volume of produced fluids, rather than planting on the surface of the oilfield equipment. The sticking rate in the presence of a known composition reaches 10%, and in the presence of the claimed up to 4-5%, i.e. 2 times less. The amount of surface glossing in the presence of a known composition reaches 20%, and in the presence of the claimed 5%. The same, approximately, picture is observed when testing the known and claimed compositions on medium (Severo-Kama field, Verey deposit, density 0.842 g / cm ³ ) and light (Konstantinovsky field, Bashkir deposit, density 0.812 g / cm ³ ) oils ( see table 4). In the study of the known and claimed compositions, oil and water were selected after passing through pieces of the studied compounds. For determination, oil, produced water and asphalt-resin-paraffin deposits of the Konstantinovsky, Pavlovsky and Severo-Kama deposits were taken. More detailed characteristics of the oils used in the research, associated water and paraffin deposits are given in table. 5, 6, 7.

The composition proposed by the authors for a complex effect on the produced fluids in comparison with the composition known for the prototype has new properties, namely:
- provides more effective prevention of sedimentation deposits during the extraction of all types of oils: light (density 0.804-0.840 g / cm ³ ), medium (density 0.841-0.880 g / cm ³ ), heavy (density 0.881-0.925 g / cm ³ ) with various the content of asphaltenes, resins, paraffins;
- provides a longer and more stable removal of the scale inhibitor due to an increase in its concentration in the claimed composition and lower solubility of the carrier substance used - bottoms from the production of amines C ₁₇ -C ₂₀ (production waste);
- in the preparation of the claimed composition, ingredients are used that are currently being produced in Russia, while the prototype contains ingredients that are not currently available either from us or abroad, i.e. it is practically impossible to cook, and therefore use. Thus, at present, only the claimed composition is capable of complexly affecting the produced fluids, i.e. at the same time to prevent the deposition of salts and ASWA at any watering of reservoir fluids, at any reservoir pressure and at any composition of the produced water. In addition, the inventive composition includes production waste - bottoms production of amines C ₁₇ -C ₂₀ , thereby solving not only the issue of disposal of this waste, but also its use, i.e. Efficient utilization of the waste from the production of amines C ₁₇ -C _{20 is} ensured, thereby solving one of the burning issues of our time - environmental protection.

 The inventive composition is capable of limited solubility at the same time both in oil and in water, i.e. when fed into the well, it works equally efficiently, protecting oilfield equipment from scaling and ASWA in conditions of constantly changing water cut of well production.

 The inventive composition is able to prevent the deposition of salts and ASWA at any water cut in the produced oil.

These technical advantages of the claimed structure allow:
- to provide, without additional treatments, a stable, simultaneous, effective supply of a phosphorus-containing reagent-inhibitor of scale deposition and an inhibitor of ARPD.

 Dosing the scale inhibitor at the lowest effective concentrations, which ensures their compatibility with simultaneously produced waters of various compositions and does not form secondary secondary sediments that could clog productive formations.

 Prevent scaling and paraffin deposits during oil production from reservoirs with any degree of permeability and with any reservoir pressure.

 To prevent the process of scaling and paraffin deposits from the very beginning of the technological chain of production, collection, preparation and transportation of oil.

 Provide effective protection of deep and surface oilfield equipment from scaling and paraffin deposits along the entire path of the oil and water flow.

The economic effect of the use of the proposed composition for a comprehensive effect on the produced fluids will be due to:
reduction of labor costs associated with the debts of the crews of underground and overhaul wells for operations to remove ASW and scaling, as well as costs associated with the prevention of only one type of complications;
increase in current oil production, as the duration of the inhibitory properties of the composition and the overhaul period of the well increases due to the comprehensive prevention of two types of deposits in one operation.

 Exclusions of additional well treatments by scaling inhibitor or paraffin deposits.

 Estimated economic effect under these articles, calculated according to RD 39-0147014-343-86 "Methodological guidelines for determining the economic efficiency of corrosion and sediment control and non-destructive testing of oilfield equipment" and RD 39-0147035-202-86 "Guidelines for the determination of the economic efficiency of new equipment, inventions and rationalization proposals in the oil industry "will be about 50 million rubles per year per 1 production well.

 The possible annual volume of use of the proposed invention in Russian fields will be at least 10,000 wells.
