Abstract
The invention provides a composite gel type profile control agent for an oil field water injection well. The composite gel type profile control agent comprises the following components in percentage by weight: 2% of dispersing agents, 0.6% of suspending agents, 0.4% of thiocarbamide, 0.5% of red vitriol and the balance of water. The composite gel type profile control agent for the oil field water injection well, which is provided by the invention, can be used for effectively regulating the water injection interlayer difference of the water injection well and enhancing the water injection effect, thereby increasing the producing reserve of a low-permeability oil reservoir, enhancing the recovery rate, increasing the output and enhancing the economic benefit.
Description
Technical field
The present invention relates to a kind of water injection well in oil fields composite gel type amendment and application thereof, belong to Low-permeability and low-pressure reservoir Profile Control in Injection Well technical field.
Background technology
Domestic each elephant is in the time of Low-permeability and low-pressure reservoir waterflooding at present, test and find that the each interval water suction of fractional flooding well situation difference is large by intake profile, part interval has the problem even not absorbing water a little less than water suction, part oil reservoir fingering problem is serious, cause water filling to be imitated water content of oil well rise too fast, water breakthrough, water logging, cause oil displacement efficiency to reduce, reduced LOW PERMEABILITY RESERVOIR mining-employed reserves, reduce recovery ratio, reduced economic benefit.Therefore need the gordian technique solving is how to adjust water injection well water filling interlayer difference problem, improve flood effectiveness.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of water injection well in oil fields composite gel type amendment, can effectively adjust water injection well water filling interlayer difference, improve flood effectiveness.
Object of the present invention is achieved by the following technical programs:
A kind of water injection well in oil fields composite gel type amendment, comprises following ingredients composition: by percentage to the quality, dispersion agent 2wt%, suspension agent 0.6wt%, thiocarbamide 0.4wt%, arsenic 0.5wt%, its surplus is water.
In above-mentioned water injection well in oil fields composite gel type amendment, preferably, the dispersion agent adopting is organic phenol.
In above-mentioned water injection well in oil fields composite gel type amendment, preferably, the dispersion agent adopting is Resorcinol.
In above-mentioned water injection well in oil fields composite gel type amendment, preferably, the suspension agent adopting is cationic polyacrylamide.
Water injection well in oil fields composite gel type amendment provided by the invention is prepared by following steps: successively dispersion agent, suspension agent, thiocarbamide and arsenic are added to the water respectively, stir, obtain water injection well in oil fields composite gel type amendment of the present invention.
The present invention also provides the application in profile control flushing well of above-mentioned water injection well in oil fields composite gel type amendment.
Outstanding effect of the present invention is:
Utilize water injection well in oil fields composite gel type amendment of the present invention to carry out profile control operation, can effectively adjust water injection well water filling interlayer difference, improve flood effectiveness, thereby improve LOW PERMEABILITY RESERVOIR mining-employed reserves, improve recovery ratio, increase output, increase economic efficiency.
Brief description of the drawings
Fig. 1 is water entry and water suction situation map before regulating section of oil wells;
Fig. 2 is water entry and water suction situation map after regulating section of oil wells.
Embodiment
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, so that technical solution of the present invention is easier to understand, grasp.
Embodiment
The present embodiment provides a kind of water injection well in oil fields composite gel type amendment, comprises following ingredients composition: 18 tons of dispersion agents, 5.4 tons of suspension agents, 3.6 tons of thiocarbamides, 4.5 tons of arsenic, 868.5 tons, water.
Above-mentioned water injection well in oil fields composite gel type amendment is prepared by following method:
First in dosing pond, inject required clear water, then add dispersion agent, suspension agent, thiocarbamide and arsenic, stir, obtain water injection well in oil fields composite gel type amendment.
The water injection well in oil fields composite gel type amendment of above-mentioned preparation is injected to Naiman oilfield, and how 1-52-50 well carries out profile control operation, before profile control, water entry and water suction situation are as shown in Figure 1, after profile control, water entry and water suction situation are as shown in Figure 2 (in Fig. 1 and Fig. 2, X-coordinate is water regain numerical value (unit is %), ordinate zou is water entry), after profile control, former water regain higher 18, 19-20, 22-23 layer water regain drops to 0 by 73.73%, 32-33, the water regain of 34-35 layer rises to 73.63 by 26.27%, the former 27-30 layer water regain not absorbing water rises to 26.36% by 0, reach high water accepting layer and reduced water regain, low water accepting layer or not water accepting layer increase the profile control effect of water regain.
Therefore, utilize the water injection well in oil fields composite gel type amendment of the present embodiment can effectively adjust water injection well water filling interlayer difference, improve flood effectiveness, thereby improve LOW PERMEABILITY RESERVOIR mining-employed reserves, increase output, increase economic efficiency.
