Abstract

The industrial solid foaming agent composition is used in foaming deairing well drilling and provides excellent foaming performance and foaming stability. The solid foaming agent composition features that the solid foaming agent has anionic surfactant as main material accounting for over 25 wt% and contains also stabilizer, tackifier, co-solvent, chelating agent and other components, and all the components are mixed homogeneously and extruded to form the solid foaming agent. When used, the solid foaming agent added into water at 25-100 deg.c to form the foam liquid. The solid foaming agent has the advantages of high foaming performance, high resistance to high calcium ion water, etc.

Description

A kind of solid blowing agent
Technical field
The invention provides the whipping agent that a kind of oil-gas field foam discharge opeing drilling well is used.
Background technology
Compare with traditional gaslift discharge opeing shaft drilling method, foam discharge opeing drilling well more and more shows its superiority, and its technological core is exactly a whipping agent, uses it in order to discharge well water etc.The patent No. is 89108127.5, name is called the whipping agent that preparing foam fracturing is used, and contains anion surfactant-straight-chain alkyl sulfate class in its composition and plays foaming effect, make stablizer with lauryl alcohol, tackifier adopt Natvosol, solubility promoter has then adopted ethanol, and water dispersible is bad, and whipping agent is a liquid-type, its foam stability can reach 37min, and oil-water emulsion is not strong, because the tensio-active agent of this liquid-type whipping agent is single, only limits to be used in wellfracturing.
Summary of the invention
The purpose of this invention is to provide that foaminess is good, high temperature resistant, the solid blowing agent of salt tolerant.
The present invention by weight percentage, its component is:
Straight-chain alkyl sulfate class 15%-45%
Fatty alcohol sulphuric acid salt 5%-40%
Fat alcohol polyethylene ether sodium sulfate salt 2%-10%
Alkylol amide 2%-10%
Water glass 2%-15%
Polyvinyl alcohol 2%-12%
Xylo-Mucine 1%-8%
Sodium ethylene diamine tetracetate 1%-6%
Usefulness of the present invention is:
1. moulding easily, dry easily, can directly drop in the water during use, easy to use.
2. when water-soluble, foaming power is strong, and concentration is that 0.2% foaming agent solution can make 4.8-5.6 that foam volume reaches the original solution volume doubly.Foamed stability is good, and half froth breaking phase reached 70min, can reach 90min during high temperature.
3. have high temperature resistant preferably, salt tolerance, be not vulnerable to the pollution and the interference of mine water.
4. the drilling depth of Shi Yonging generally can reach 1000-1500m, if when surpassing 2000m, if temperature is no more than 100 ℃, still can use, and joining the underground water-injection effect simultaneously can be more.
5. the concentration of Shi Yonging can be controlled in 0.2%-2%.
