Abstract
The present invention relates to hydrophobic oleophilic finishing agent and a preparation method thereof, which belongs to the technical field of petrochemical industry. The hydrophobic oleophilic finishing agent comprises water, cationic surfactant and organics which is absorbed on core surfaces and can cause the core to reverse in a wet type, and the present invention has the weight proportion of components that 100 portions of water, 1 to 20 portions of cationic surfactant and 1 to 120 portions of organics. The present invention has the preparation method that the cationic surfactant is added into the water and is filled into a colloid mill after heating to 85 to 90 DEG C, 120 to 140 DEG C organics can be added secondly, and then the present invention can be discharged. The hydrophobic oleophilic finishing agent of the present invention can be filled into an oil well so as to be tightly stuck with cores, a near well stratum of the oil well can ne reversed as a hydrophobic oleophilic surface from a hydrophilic surface, and the validity period can be kept more than two months.
Description
Technical field
The present invention relates to oil well surrounding stratum hyphobic lipophilic treating additive and preparation method thereof, belong to the petrochemical technology field.
Background technology
In drilling well, completion, production and the stimulation treatment process of oil well, water is assembled in the immediate vicinity of wellbore of oil reservoir, causes the bottom water blocking, has promptly reduced the rate of permeation of crude oil, has just hindered crude oil and has flowed to oil well from the stratum, reduces oil well output.Therefore, improve well recovery speed, reduce water ratio, removing water blocking has much relations with the water of getting rid of the immediate vicinity of wellbore, stratum, and the crude oil reservoir all is hydrophilic usually, and the core that promptly constitutes oil bearing reservoir is hydrophilic, water-moistened in other words conj.or perhaps, and in every operation process of oil well, the water in the well control fluid infiltrates to the stratum, and the crude oil of immediate vicinity of wellbore is expelled pit shaft, the capillary force of core can't be offset again, cause the fuel-displaced difficulty of oil well, production capacity reduces, and the adjacent to oil well area core is changed into hydrophobic oleophylic interface by hydrophilic interface, improve oil well oil permeability on every side, reduce the rate of permeation of water,, reach the effect of decreasing water cut and increasing oil to remove water blocking.Hydrophobic oleophylic treatment agent of the present invention is handled adjacent to oil well area, and wetting to change oleophylic into wetting by hydrophilic to make its core, is improved oil permeability around the oil well and reaches and increase oily purpose.
Summary of the invention
The invention provides a kind of oil well surrounding stratum hyphobic lipophilic treating additive and preparation method thereof, this hydrophobic oleophylic treatment agent is used for the oil increasing precipitation operation of production oil well in oil field and the profile control of well.
Hydrophobic oleophylic treatment agent of the present invention comprises water, cats product, is adsorbed in the organism that the core surface can make its moist type counter-rotating, and component is as follows, is weight part:
100 parts in water
Cats product 1～20
Organism 1～120.
Above-mentioned cats product can be one or more of hexadecylamine acetate, hexadecyldimethyl benzyl ammonium amine acetate, hexadecylpyridinium chloride, hexadecyldimethyl benzyl ammonium Phenyl chloride, octadecylamine acetate, two (octadecyl) alkyl dimethyl ammonium chloride, octadecyl chlorination pyridine, octadecyl divinyl triamine diacetin etc.
But organism crude oil, pitch, organosilicon, organic acid or paraffin.
Preferred heavy oil of above-mentioned crude oil or light oil.
Above-mentioned organic acid preferred fatty acid.
When organism was pitch or paraffin, during the preparation method of hydrophobic oleophylic treatment agent of the present invention, Xiang Shuizhong added cats product, is heated to 85～90 ℃ of injection colloidal mills, adds 120-140 ℃ of organism then, is uniformly dispersed discharging.Should note insulation in the preparation process.When selecting other organism for use, preparation gets final product under the room temperature, and method is as follows:
Add entry, cats product successively to the high-speed stirring still, add organism then, stirred discharging 20 minutes.
Hydrophobic oleophylic treatment agent of the present invention has positive charge and can attract each other with the hydrophilic rock stratum around the oil well that has negative charge, make emulsion breaking, the lipophilic organism of hydrophobic bonds or is bonded on the core by cats product, make the rock stratum by the hydrophilic oleophyllie hydrophobic rock stratum that is reversed to, reach and increase the purpose that oil blocks water.Hydrophobic oleophylic treatment agent of the present invention injects oil well, can with the core secure bond, make the oil well near wellbore formation be reversed to the hydrophobic lipophilic surface, and the phase of remaining valid is more than two months by hydrophilic surface.Use the pilot-scale experiment of 10 mouthfuls of job executions that hydrophobic oleophylic treatment agent of the present invention carries out at Gudong field to show that it is stifled not only successfully to have removed oil-reservoir water, the oil offtake of oil well is risen significantly, and water ratio obviously descends.The present invention provides a kind of new method for oil well yield increasing of Cheap highly effective for petroleum industry.
