The paraffin cleaner has the advantages that: the unit-released heat of the chemical paraffin cleaner is large, and the produced heat only acts in the oil pipe; the paraffin cleaning efficiency is high, and the application cost is low. The paraffin remover is located correctly by using the limiter, without affecting the advancement of oil exploitation, thereby being beneficial to storage, transmission, application and location, and the reaction products do not corrode the oil pipe.
Description
Technical field:
The present invention relates to a kind of petroleum recovering operation control and remove of well paraffin device.
Background technology:
The tubing wax problem is the well-known difficult problem of industrial gas oil always.If wax deposition occurs near stratum or the well head, remove then very difficulty or may not dispose.
The oil pipe wax removal is mainly taked three kinds of methods or integrated application at present.1) mechanical paraffin removal method uses ground installation equipment to carry out paraffin removal, and this is applicable to the oil well that the wax deposition degree is lower; 2) paraffin removing with chemical method method adopts the number of chemical paraffin remover, and as dispersing agent, crystal modifier etc., purpose is dissolving paraffin and it is pumped from system.The subject matter that this method exists is that the paraffin removing with chemical method agent costs an arm and a leg; 3) thermosoling is to rely on outside heat to come melted paraffin and take it out of oil well, for example deep fat method well-flushing wax removal is exactly a kind of of hot melt, this method is that the heating crude oil that is stored in the oil tank is injected the oil jacket annular space then to quite high temperature, realizes the wax removal purpose.When fluid flows into annular space, can produce certain thermal loss, and also cause paraffin deposit in the deep fat in the shaft bottom, bring bigger trouble to production.
Traditional chemical heat generating wax removal system was also once used in the industry of oil field, wherein the chemical heat generating wax removal system of Shell Co. Ltd's research and development was used in No. 3 oil reserve storehouses of naval in 1984, two kinds of solution that utilize are natrium nitrosum and ammonium nitrate or ammonium chloride, paraffin remover is a liquid, is difficult for transportation and uses inconvenient.
Summary of the invention:
The objective of the invention is to avoid above-mentioned deficiency and provide a kind of oil well chemical original position to give birth to hot paraffin cleaner, the heat of generation is big, and can inject the shaft bottom from the oil well annular space.
The object of the present invention is achieved like this:
A kind of manufacture method of chemical paraffin cleaner, main body is made of the column type pipe, and the restricted device in top is connected with oil pipe, and diameter and oil pipe adapt, and the wall perforate is arranged on the main body pipe, and the wall perforate has 3--5 row, the every row outer hole of 20-50 that evenly distributes.The bottom of main body pipe is sealing, and paraffin remover is equipped with in inside, and paraffin remover is a column type, and external diameter is less than the main body bore, and the outside is a foreskin, and the thickness of foreskin is no more than 0.1mm, and chemical agent is equipped with in inside.Chemical agent is metal or its alloys such as aluminium, calcium, magnesium, potassium, sodium, lithium, and compound, or calcium carbide etc., foreskin is thin paper or aluminium foil.
Purpose of the present invention can also realize like this: paraffin remover is a ball-shaped, and diameter is less than the main body bore, and the outside is a foreskin, and the thickness of foreskin is no more than 0.1mm, and inner core is a chemical agent.
Compared with prior art, advantage of the present invention is that paraffin removing with chemical method agent unit release heat is big, and the heat that produces only acts in the oil pipe, wax removal efficient height, and application cost is low, paraffin remover accurately can be located with limiter, and can not influence the carrying out of follow-up oil extraction operation,, help storing, transport, use and locating with metal or nonmetal crust parcel, the gas that produces is more favourable to the dissolving of wax, and product is not corroded oil pipe.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a ball-shaped paraffin remover structural representation.
Fig. 3 is a column type paraffin remover structural representation.
The specific embodiment:
Be described in detail embodiments of the invention below in conjunction with accompanying drawing.
A kind of manufacture method of chemical paraffin cleaner, main body is made of the column type pipe, and the restricted device 1 in top is connected with oil pipe, and diameter and oil pipe adapt, and wall perforate 2 is arranged on the main body pipe, and wall perforate 2 has 3--5 row, the every row 20-50 wall perforate 2 that evenly distributes.The bottom of main body pipe is sealing plug 4, and paraffin remover 3 is equipped with in inside, and to electric pump well and flowing well, paraffin remover 3 is a column type, and external diameter is less than the main body bore, and the outside is a foreskin 5, and the thickness of foreskin 5 is no more than 0.1mm, and chemical agent 6 is equipped with in inside.
By limiter 1 paraffin remover 3 is fixed in the oil pipe bottom and arrives the purpose oil reservoir,, improve in-place permeability newly opening the oil-well strata cleaning, to rod-pumped well, paraffin remover 3 is a ball-shaped, and diameter is less than the main body bore, the outside is a foreskin 5, and the thickness of foreskin 5 is no more than 0.1mm, and inner core is a chemical agent 6.
The equation of this reaction:
M+H
2O--M(OH)
N+Mh
2+ΔH
M is that chemical agent is metal or its alloys such as aluminium, calcium, magnesium, potassium, sodium, lithium, and compound, or calcium carbide etc.
The foreskin 5 of paraffin remover 3 is thin paper or aluminium foil, needs water or watery hydrochloric acid corrosion, uses the hydrochloric acid solution of the plastic tank configuration 1%-10% of the 1-3 cubic meter of being with valve, sends into the oil pipe assigned address with acid-proof pump.
As: calcium carbide 80 grams (80%) are put into water, and reaction heat is 127KJ/mol.
As: the reaction heat of sodium metal and water is 185KJ/mol.
As a kind of stimulation of well, mainly can be used for:
1) oil well production increasing, the starting stage of after completion, recovering the oil, can heat the near wellbore zone, stratum with giving birth to a large amount of heat of hot pin generation, colloid, asphalitine and paraffin deposit in the stratum are melted.And, at this moment the heat alkali liquid of Chan Shenging also can remove the pollutant on stratum and with it by getting rid of in the stratum.When the permeability of near wellbore zone, stratum reached the permeability on stratum, the effect of increasing production of oil well was best.
2) heat chemistry wax removal, the heat of generation directly are diffused on the paraffin that is deposited on the oil pipe, and therefore the thermal loss that can avoid deep fat well-flushing wax removal to cause especially is applicable to the wax removal to flowing well and electric pump well.
3) thickened oil recovery is given birth to a large amount of heat of hot pin generation and can be made viscous crude intensification viscosity reduction, improves flowability, and the surface-active substance of generation can play the effect that makes thick-oil emulsified adhesive-reducing.
