Abstract
The invention relates to the technical field of fine petroleum processing and in particular relates to a preparation method of a weak gel deep profile control agent. The preparation method of the weak gel deep profile control agent comprises the following steps: 1, preparing raw materials; 2, preparing a polymer main agent; and 3, preparing a crosslinking agent. The method provided by the invention is simple and easy to operate, and can reach an experiment condition easily, and a weak gel prepared by the method provided by the invention has relatively high viscosity and an appropriate gel-forming time and can be used for deep profile control.
Description
Technical field
The present invention relates to meticulous Petroleum Processing Technology field, be specifically related to a kind of preparation method of Weak Gels deep electrical structure.
Background technology
Crosslinked polymer flooding can give full play to the advantage of cross-linked polymer, realizes high injectability and extensive injection, plays regulating effect to oil reservoir internal flow.Crosslinked polymer flooding can not only play the effect of profile control, water blockoff, simultaneously can contradiction between regulating course or in layer, increases swept volume.By the classification of polymkeric substance working concentration, cross-linked polymer can be divided into 2 kinds: one to be colloidal dispersed gel or can the low concentration polymer system such as flow-gel; Two is weak gel profile displacement systems.
Weak Gels is a kind of gelling system formed by low concentration polymer and linking agent, can significantly reduce chemical agent consumption.Large quantity research shows, Weak Gels or colloidal dispersed gel (CDG) Novel technique of in-depth profile control economically feasible, have good application prospect.
Summary of the invention
The present invention is intended to the preparation method proposing a kind of Weak Gels deep electrical structure.
Technical program of the present invention lies in:
A preparation method for Weak Gels deep electrical structure, comprises the following steps:
Step 1: prepared by starting material:
Sodium.alpha.-hydroxypropionate, crystal aluminum chloride, trisodium citrate, sodium acetate, thiocarbamide, polyacrylamide;
Step 2: the preparation of polymkeric substance host:
Take Polyacrylamide Powder, preparation polyacrylamide solution mother liquor, and the mother liquor dilution that will prepare;
Step 3: the preparation of linking agent:
(1) take 25g trisodium citrate, sodium acetate, Sodium.alpha.-hydroxypropionate and aluminum chloride respectively, adding distil water is dissolved in beaker respectively, and moves respectively in the volumetric flask of people 250 mL, is mixed with the salts solution of 10%;
(2) by amount of substance than for 1:1, aluminum chloride being mixed with linking agent with trisodium citrate, sodium acetate and Sodium.alpha.-hydroxypropionate respectively.
Preferably, whipping appts employing JJ-3 six electric mixer that described dissolving is used.
Preferably, described starting material are chemical pure material.
Technique effect of the present invention is:
Method provided by the invention is simple, and easy handling, experiment condition is easy to reach, and the Weak Gels obtained by method provided by the invention has higher viscosity and suitable gelation time, can be used for deep profile controlling.
