Description
Technical field:
Crosslinked amphoterics fracturing liquid under the strong acidic condition that the present invention relates to use in a kind of applicable Oil in Super-low Permeability hydrocarbon zone oil well or gasser fracturing yield increasing technique.
Background technology:
At present, Oil in Super-low Permeability hydrocarbon zone reservoir properties is poor, and rate of permeation is low, and pore throat is trickle, and 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 eject after height is pressed into, system residue content is higher, the flow conductivity of fracture easily causes permanent injury, acid surface active agent fracturing liquid is without residue, the acid soluble mineral of acid in system in can 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 having can realize thickening under higher concentration acid (acid concentration is greater than 10%) condition and take sand, but what host adopted is cats product, because reservoir sandstone surface is generally electronegative, cats product often adsorptive capacity is large, the row's of returning difficulty and injury are larger, what some system host adopted is anion surfactant, and the row of returning is thorough, injure little, still can not thickening in sour environment, or can only realize thickening at lower concentration acid environment (concentration of hydrochloric acid 1-3%) and take sand.
Summary of the invention:
The object of the present invention is to provide in a kind of applicable Oil in Super-low Permeability hydrocarbon zone oil well or gasser fracturing yield increasing technique, use can be crosslinked under strong acidic condition amphoterics fracturing liquid.
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, clear water
Described acid surface active agent fracturing liquid mixes taking volume ratio solution A, solution B as 100: 8～12 ratio, make 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 Sodium dodecylbenzene sulfonate.
Described gel breaker host material is sodium lauryl sulphate, after industrial emulsion is sealed, for diameter is at the circular granular of 500 microns of left and right.
Described industrial emulsion is 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 Sodium dodecylbenzene sulfonate; mix and can in the hydrochloric acid of 1%-12%, realize thickening by a certain percentage, at 170s
-1shear continuously 90min, viscosity in 50mPa.s left and right, can realize and take 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 carrying out three aspects: of fracturing liquid.
1, New stablization
The present invention can be crosslinked under strong acidic condition the of the fracturing fluid host of the amphoterics thickening material that is a kind of new research and development, this thickening material is two kinds of zwitterionicss, this viscosifying agent is little in sandstone surface adsorptive capacity.
2, novel crosslinker
The present invention is directed to zwitterionics feature, researched and developed novel crosslinker.
3, the domestic concentration of hydrochloric acid of having realized is first greater than the crosslinked sand of taking under 10% condition.
Embodiment:
