Abstract
The present invention relates to a solid foaming agent compound for industrial use, which provides favorable foaming performance and foaming stability for foam deaering well drills. The solid foaming agent compound is characterized in that an anionic surfactant as principal raw material which accounts for more than 25 wt% of the whole formula, stabilizer, tackifier, cosolvent, chelating agents and the like are mixed, uniformly stirred, and then filled into a solid forming extrusion device to prepare the solid foaming agent. When used, the solid foaming agent is added into the water at the temperature of 25 to 100 DEG C to form foam liquid. The solid foaming agent has the advantages of strong foamability, high calcium ionized water resistance, etc.
Description
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.

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%.
