Description
Invention field
The present invention relates to the Oilfield Chemicals using in a kind of oil and gas oil producing operation construction, particularly a kind of low-permeability oil deposit Xie Shui lock agent and preparation method thereof, is mainly used in the working fluids such as fracturing liquid, perforating fluid and well control fluid.
Background technology
Low-permeability oil deposit generally has the features such as capillary pressure is high, water sensitivity is strong and pore throat is tiny, poor permeability, serious heterogeneity.In oil production process, working fluid is easy to occur water capillary imbibition, causes a large amount of working fluids to enter oil reservoir.The poor permeability of low-permeability oil deposit, the working fluid that causes invading oil reservoir returns row's difficulty, even can not the row of returning, form water blocking damage.Study and show both at home and abroad, water blocking damage is main, the most serious type of injury of low-permeability oil deposit, and damaging factor is generally 70%～90%, once come to harm, it is more difficult that oil reservoir perviousness is recovered, and long-term effect single well productivity, oil reservoir production efficiency increase cost of development.
The earliest, the main natural gas pool aspect of concentrating of water blocking damage research that people carry out, in recent years along with development of low-permeability oil reservoir, people have strengthened the research to oil reservoir water blocking damage mechanism, extent of injury prediction aspect.As D.B.Bennion etc. thinks, liquid phase is assembled and is detained in hydrocarbon-bearing pool is the principal element of water blocking damage, and rate of permeation is lower, affects more serious; Li Shubai is studied the Forecasting Methodology of liquid phase trap infringement with multivariate analysis in regressive, has set up the functional relation between liquid phase trap harmful penetrance recovery value and reservoir permeability and porosity.
Along with the progressively intensification of people to water blocking damage understanding, to strengthen understanding the development except water blocking damage chemical agent, portioned product has carried out rig-site utilization, and effect is comparatively remarkable.The disclosed patent WO of U.S. CONOCOPHILLIPS CO, 2004096940[P] be a kind of water lock agent for releasing of hydrocarbon-containifirst tensio-active agent; The disclosed patent MX of U.S. UNIV TEXAS, 2009010142[P] relate to a kind of oil well Xie Shui lock agent and process the method for hydrocarbonaceous petroclastic rock.The people such as Xue Yuzhi develop sulfonated petro-leum, rhamnolipid and sodium carbonate compound system [< < Drilling and completion fluids > > 2009, Vol.26 No.6], can effectively improve the perviousness of Pinghu Oil and Gas Field low permeability reservoir; Ma Hongxing develops PWA water blocking damage treating agent [< < oil-gas geology and recovery ratio > > 2005 for chengdao oilfield low pressure well, Vol.26 No.4], well prevent and remove water block effect.
Rig-site utilization shows, the Xie Shui lock agent of single type is difficult to take into account the factors such as geology, reservoir condition and construction technology of low-permeability oil deposit, removes water blocking damage effect undesirable, is of limited application.Therefore, the Xie Shui lock agent that research and development are formed by two or more surfactant compound becomes trend, to improve the immunity from interference of Xie Shui lock agent, expands its range of application.
Summary of the invention
The present invention is difficult to take into account the factors such as geology, reservoir condition and construction technology of low-permeability oil deposit in order to solve the Xie Shui lock agent of single type, remove water blocking damage effect undesirable, the technical problem such as be of limited application, it is strong that the present invention one is to provide a kind of surfactivity, make working fluid return row easily, can efficient solution remove water blocking damage, maintain the infiltrative low-permeability oil deposit Xie Shui lock agent of oil reservoir; Two are to provide the preparation method of a kind of low-permeability oil deposit Xie Shui lock agent.
Solve the problems of the technologies described above by the following technical solutions: the agent of a kind of low-permeability oil deposit Xie Shui lock, it is characterized in that: described low-permeability oil deposit Xie Shui lock agent comprises glycol ether, two dodecyl Sodium Dicarboxylic Acid, ethylene glycol silicon ether and water with raw material, by mass percentage, glycol ether 1～15%, two dodecyl Sodium Dicarboxylic Acids 15～45%, ethylene glycol silicon ether 5～30%, water 30～60%, described glycol ether is a kind of of ethylene glycol monobutyl ether, diethylene glycol ether, Polyethylene glycol dimethyl ether; Described two dodecyl Sodium Dicarboxylic Acids are N, N'-bis-(dodecyl) quadrol base dipropionic acid, N, N'-bis-(dodecyl) quadrol base sodium diacelate, N, N'-bis-(dodecyl) butanediamine base dipropionic acid, N, N'-bis-(dodecyl) butanediamine base sodium diacelate a kind of; Described ethylene glycol silicon ether is a kind of of ethylene glycol trimethylsilyl ethers, ethylene glycol triethyl silicon ether, polyoxyethylene glycol trimethylsilyl ethers, polyoxyethylene glycol triethyl silicon ether.
A preparation method for low-permeability oil deposit Xie Shui lock agent, the device that described method is used comprises reactor stirrer, it is characterized in that, its preparation method comprises the steps: mass percent meter, in enamel reaction still, add 30～60% water, start stirrer, water is heated to 30～40 ℃; Then in reactor, add 1～15% glycol ether, 15～45% pairs of dodecyl Sodium Dicarboxylic Acids, temperature control stirring 1h; And then add 15～30% ethylene glycol silicon ethers, and controlling temperature at 40～80 ℃, reaction 1～2h obtains Xie Shui lock agent finished product.
Adopt technique scheme, compared with prior art, low-permeability oil deposit Xie Shui lock provided by the invention agent mainly contains three kinds of active ingredients: two dodecyl Sodium Dicarboxylic Acids, ethylene glycol silicon ether, glycol ether.Two dodecyl Sodium Dicarboxylic Acids are a kind of Gemini surface active agent (Gemini Surfactants), have high surfactivity, and water-soluble better.Ethylene glycol silicon ether is a kind of organic silicon ether type tensio-active agent, has good synergistic effect with two dodecyl Sodium Dicarboxylic Acids.Glycol ether is Xie Shui lock agent active ingredient, can improve again the water-soluble of two dodecyl Sodium Dicarboxylic Acids, reduces the cloud point of Xie Shui lock agent.A kind of low-permeability oil deposit Xie Shui lock agent surfactivity the present invention relates to is strong, makes working fluid return row easily, can efficient solution remove water blocking damage, maintains the perviousness of oil reservoir.Its significant effect is: preparation method's science of the present invention, the product surface obtaining is active by force, consumption is few, strong adaptability, applied range.Can be used for the many kinds of measures operation in natural petroleum gas field process, in the working fluids such as fracturing liquid, perforating fluid, well control fluid.
