Description
Technical field:
The present invention relates to a kind of crosslinked amphoterics fracturing liquid under the employed strong acidic condition that is fit in ultralow oil impregnate gas-bearing formation oil well or the gasser fracturing yield increasing technology.
Background technology:
At present, ultralow oil impregnate gas-bearing formation reservoir properties is poor, and rate of permeation is low, and pore throat is trickle, and the face rate is low, and per-well production is low, but acid soluble mineral content is generally higher.Conventional guanidine gum fracturing fluid is difficult to return after height is pressed into eject; The system residue content is higher, and fissured flow conductivity is prone to cause permanent injury, and the acid surface active agent fracturing liquid does not have residue; The acid soluble mineral of acid in the system in can the corrosion reservoir further improves reservoir permeability and further improves per-well production; But present acid surface active agent fracturing liquid performance is not too perfect: the system that has can realize that sand is taken in thickening under higher concentration acid (acid concentration is greater than 10%) condition, is cats product but host adopts, because the reservoir sandstone surface is generally electronegative; Cats product often adsorptive capacity is big, and the row's of returning difficulty and injury are bigger; What the system host that has adopted is AS, and the row of returning is thorough, injure little, still can not thickening in sour environment, perhaps can only take sand in lower concentration acid environment (concentration of hydrochloric acid 1-3%) realization thickening.
Summary of the invention:
The object of the present invention is to provide a kind of employed can be under strong acidic condition crosslinked amphoterics fracturing liquid in ultralow oil impregnate gas-bearing formation oil well or the gasser fracturing yield increasing technology that is fit to.
Crosslinked amphoterics fracturing liquid under a kind of strong acidic condition of the present invention is the mixture with following composition and weight part:
A solution:
B solution:
4～6 parts of linking agents
94～96 parts in clear water
Described acid surface active agent fracturing liquid is 100: 8～12 mixed with solution A, solution B with volume ratio, processes the acid surface active agent fracturing liquid.
Described acid surface active agent fracturing fluid thickener is two lauroyl propyl-dimethyl trimethyl-glycines and oleoyl propyl-dimethyl trimethyl-glycine, and part by weight mixes at 1: 1.
Described linking agent is an X 2073.
Described gel breaker host material is a sodium lauryl sulphate, after sealing through industrial emulsion, is the circular granular of diameter about 500 microns.
Described industrial emulsion is a rosin.
The of the fracturing fluid host of acid surface active agent of the present invention is that a kind of thickening material is two lauroyl propyl-dimethyl trimethyl-glycines and oleoyl propyl-dimethyl trimethyl-glycine; This thickening material is two kinds of amphotericses; Linking agent is an X 2073; Mix by a certain percentage and can in the hydrochloric acid of 1%-12%, realize thickening, at 170s
-1Shear 90min continuously, viscosity about 50mPa.s, can realize taking sand continually and steadily.Gel breaker is the sodium lauryl sulphate of rosin parcel, and breaking glue solution is thorough, and viscosity is less than 5.0mPa.s.
The present invention is in the technical innovation of having carried out aspect three of fracturing liquid.
1, novel thickening material
The present invention can the crosslinked of the fracturing fluid host of amphoterics be a kind of thickening material of new research and development under strong acidic condition, and this thickening material is two kinds of zwitterionicss, and this viscosifying agent is little in the sandstone surface adsorptive capacity.
2, novel crosslinker
The present invention is directed to the zwitterionics characteristics, researched and developed novel crosslinker.
3, the domestic concentration of hydrochloric acid of having realized first is greater than the crosslinked sand of taking under 10% condition.
Embodiment:
