Description
Technical field
The invention belongs to the technical field of oilfield chemistry product, be specifically related to the novel pore forming material of using in a kind of fracture acidizing liquid.
Background technology
In acidification of oil field fracturing reform, in order to obtain the ideal effect of fracture acidizing volume increase, general requirement active acid sphere of action is large, stretches out as far as possible.Because foamed acid has slowly, liquid content is few, low leak-off, and the feature such as polluted reservoir not, therefore, in the oil formation improvement of oil field, application is very extensive.
In foam acid solution, crucial pore forming material (whipping agent), has had its acid solution just can be called foamed acid.To its requirement, be that latherability is strong, long half time, emulsification degree is little, good with various additive compatiblenesies.Desirable pore forming material (whipping agent) must possess following performance:
1. can effectively reduce the surface tension of acid solution and the interfacial tension of oleic acid, the low interfacial tension of acid solution, easily enters in the hole on stratum acid solution, expands the process range of acid solution, is conducive to spent acid simultaneously and returns row.
2. foam is abundant, and long half time repeats lathering property good.
3. thering is good demulsification performance. in crude oil, contain natural radioactivity, oleic acid easily forms high sticky emulsification and results in blockage, and the promoting agent in acid solution must prevent acid solution emulsification effectively.
4. suspension property is good. and during acidifying, will produce some not dissolved solid particulates, acid solution has good suspending power, makes these particles discharge ground with waste liquid, is unlikely to cause secondary injury.
5. water-wet is good. and added pore forming material must guarantee the wettability on stratum, to improve permeability to oil, increases crude production rate.
6. Heat stability is good. after pore forming material enters stratum, heat will keep its activity, is so just conducive to acid discharge.
7. adsorptivity ability is low. and pore forming material will be difficult for being adsorbed by stratum, remains certain activity, and this is just conducive to the row of returning of residual acid.
At present, on market, also there are some pore forming materials, but should use certain limitation, and mostly be one-component product.Therefore, select pore forming material to select according to molecular structure, yet single molecular structure is difficult to meet acidifying pore forming material, is badly in need of having a kind of pore forming material that meets multiple performance.
Summary of the invention
The object of the present invention is to provide the novel pore forming material of using in a kind of fracture acidizing liquid, mainly solve the construction problem of the well Warm (140 ℃ following) in acidification of oil field fracturing reform.
Technical scheme of the present invention is:

The novel pore forming material of using in fracture acidizing liquid of the present invention, in proportion, operation preparation at normal temperatures and pressures, does not have three-waste pollution in order, by conventional compound method, said components is mixed and can be obtained.
Beneficial effect of the present invention is:
The bubble of being kept apart by fluid film or solid film gathers becomes foam in vitro, and the foam that only has liquids and gases to form becomes liquid foam.Thereby only have solution just can have obvious bubble, and in general, water phase surfactant mixture can bubble, and this is mainly due to its molecular structure own.
Anion surfactant pore forming material, foaming power and oleophilic group carbonatoms, the structure etc. of oleophilic group relevant, when atomicity is 12-16, foaming power is the strongest, carbon atom reaches 18 o'clock foaming powers and declines suddenly; If oleophilic group has side chain, lathering property variation; When hydrophilic group molecule is positioned at molecule central authorities, whipability significantly reduces.
The present invention is with tetradecyl sodium sulfonate, and sodium cetanesulfonate is main, and its latherability is very strong, foam height, and density and transformation period are also very good, are equipped with polyoxyethylene octylphenol ether, polyoxyethylene nonylphenol ether becomes evenly bubble, reduce broken bubble rate.Be equipped with the surface tension that Scouring agent (Amway product) and body wash (Amway product) make pore forming material simultaneously, interfacial tension is lower, is so more conducive to washing oil, is more conducive to be reduced in stratum absorption, also just improve the whipability of pore forming material in raffinate, be conducive to the row of returning of raffinate.
In a word, product of the present invention is the composite prod of various ingredients, and it is effective, is mainly used in the construction of the well Warm (140 ℃ following) in acidification of oil field fracturing reform.
