Description
The present invention relates to a kind of profile control and plugging agent of oil oil and water well exploitation, it is the adjusting agent that is used for oil and water well profile control, water blockoff.
As everyone knows,, satisfy the needs that enter middle and high Water-cut Period oil field oil increasing precipitation in order to improve the sweep efficiency that injects water, since the seventies, the existing bigger development of profile control technique both at home and abroad.
At present, polyacrylamide colloid type and powder-type have been widely used in the main raw material of profile control, the agent of water blockoff usefulness, but, because powder-type and colloid type polyacrylamide are in use, solubility property is relatively poor, easy gum deposit group, be not easy to on-the-spot the use, and need be in construction a few days ago with raw material, fully dissolve with extraneous cycling condition, just can obtain uniform colloidal solution, simultaneously in the circulation dissolution process, machinery produces shear degradation to polyacrylamide, and the molecular weight of polymkeric substance is reduced.For colloid type, because at present effective concentration has only about 10%, must increase trucking costs, dosing is for up to 7～8 days, adds the waste of upper container and packaging wrapper adhesion and rate of utilization only is 80～85% or the like defectives.
The objective of the invention is to provide a kind of dispersed suspension type polyacrylamide for adjustment analysis use, it is that to have a solid content high and dissolution rate is fast, rate of utilization is high, do not need extraneous circulation dissolving, can simplify amendment and the plugging agent of site construction technology and shortening engineering time.
The object of the present invention is achieved like this: it is to have a polyacrylamide powder of 40%, 2.5～5% organophilic clay, 3% nonionogenic tenside and 52.5～54% the formulated adjusting agent of diesel oil.Wherein organophilic clay (organobentonite) and nonionogenic tenside are composite is as the agent of anti-shallow lake, organic performance of organophilic clay is strong, in the oils liquid resin, can form gel, and have good tubeization ability, prevent the caking, change the suspension effect of solid particulate, nonionogenic tenside is dispersed in solid and the fluid simultaneously, reduce the interfacial tension (powder particle is more than 60 mesh standard sieves) between polymer beads (polyacrylamide powder) and the fluid, and diesel oil only plays carrier function.
Owing to adopt such scheme, no matter all be better than existing powder-type and colloid type polyacrylamide at solubility property and dissolution rate, preparation is convenient, and construction simply can realize the operation of the construction while preparing, thereby has alleviated labor strength, has reduced cost for oil production.
By narrating following embodiment the utility model is further specified.
A kind of dispersed suspension type polyacrylamide for adjustment analysis use (TDP-02), the light brown suspension with good fluidity is used for the oil-field flooding well profile and adjusts agent (being called for short amendment again).
Its prescription: 40% polyacrylamide powder (being called for short PHP), 3% organophilic clay, 3% nonionogenic tenside and No. 54%0 diesel oil.
Quality index: molecular weight: 300～5,000,000 or 400～6,000,000
Solid content: 〉=40%
Anion-content: 10～15
Solubility property: with ortho-water is the stirring 30 minutes of the solvent preparation solution that becomes 0.8～1% concentration, and it is even to dissolve its colloidal sol fully.
Method for formulating:
At first weigh the weight that weighs up the required four kinds of materials of above-mentioned prescription in the balance, then No. 0 diesel oil is added nonionic surface active agent, little being heated to fully dissolved, and then places below 30 ℃ stand-by.Simultaneously polyacrylamide pulvis and organophilic clay are mixed, the more organic upward mixture of polyacrylamide is slowly put into the oil product of high-speed stirring, treat to give again after 20～30 minutes middling speed and stirred 5～10 minutes, can obtain amendment (TPP-02).
The present invention is since nineteen ninety begins development and trial-production, 120 tons of TDP-02 have been produced, geographic 38 mouthfuls of oil wells are adjusted through connecting in Inner Mongolia Autonomous Region two, in the water blockoff test, draw from big quantitative statistics: one ton of TDP-02 of every input will increase by 50～100 tons of oil recoverings, simplified site construction technology simultaneously, shortened the engineering time, needed 6～7 days by original every construction a bite well, can become dosing on the same day, construction on the same day, completion on the same day.Thereby alleviating labor strength greatly, reduced cost for oil production, is the very wide amendment of a kind of application prospect.
Prove that from a large amount of tests with trying out TDP-02 of the present invention has following advantage:
1.TDP-02 solid content is 5 times of colloid solid content up to 40%, has good mobility simultaneously, only needs 1/5th of colloid trucking costs.
2. water-soluble powder-type and the colloid type polyacrylamide of being better than, dissolution rate is fast, under indoor stirring, needs dissolving fully in 20～30 minutes, and machine stirs down at the scene, only need 8～10 minutes, and solution is even, colloid dough and flake phenomenon do not occur.
3. when constructing at the scene, do not need to adopt extraneous circulating mechanical equipment to dissolve, therefore avoided the mechanical shearing degraded, can be implemented in on-the-spot preparation on the same day, construction, and variation can be adjusted dosing concentration according to operation pressure.
4. this product rate of utilization is up to more than 95%.
5. production technique is simple, feasible, and production process does not have " three wastes " discharging.
6. through the test-65 ℃～+ 35 ℃ of temperature, TDP still keeps use properties constant, molecular weight more can not occur and reduce, and therefore, is convenient to storage, constant product quality.
TDP-02 product of the present invention can be used for the water blockoff of oil and water well, in the oil productions such as adjustment, test in place and checking through Beijing Scientific Research Institute of Petroleum Exploration and Development Planning and Oil Exploitation Technique Inst. of Huabei Petroleum Administration, through Zhangjiakou City petroleum assistant factory to the trial-production of TDP-02 and carry out economic analysis, consistently generally acknowledge it is the product innovation prescription of oil, well profile modification, water blockoff rapid construction, built the whole nation and applied.Retrieve through Hebei province institute of scientific-technical information simultaneously, still found no the prescription of TDP-02.
The fatty alcohol-polyoxyethylene ether structural formula:
Organobentonite is to be the clay mineral of major ingredient to cover the shedding end, because the effect of crystalline isomorphous substitution, makes the electronegative and absorption metallic cation of lattice.These metallic cations can carry out permutoid reaction with cats product, make lipophilic organobentonite.
