The invention discloses the preparation technology of heat and salinity tolerance foam discharging agent, solves the problems, such as that existing foam discharging agent can not meet that low cost, highly dissoluble, high temperature resistance, salt resistance, foaming and foam stabilizing ability significantly require simultaneously.The present invention is included N, N ', N "-alkyl diethylene triamine pentacetic acid (DTPA) sodium, dodecyl dimethyl Hydroxypropyl phosphate fat glycine betaine and neopelex are well mixed; after heating melting; are added galactomannans and be well mixed, 3 10min are incubated in whipping process, then add neopelex; natural cooling after being stirred for uniformly, the material after cooling are ground into powdery.The present invention is not only only capable of effectively reaching low cost, highly dissoluble, high temperature resistance, salt resistance, the significant effect of foaming, and foam stabilizing effect is more notable.
Description
Technical field
The present invention relates to foam discharging agent, and in particular to the preparation technology of heat and salinity tolerance foam discharging agent.
Background technology
Foam drainaging gas cutting process technology has played important function in the exploitation exploitation of water-beating gas well, not only significantly carries
The high band liquid energy power of gas, reduces wellbore effusion, moreover it is possible to extend the production time in gas well later stage, so as to improve ultimate recovery.
With the rise of environment temperature, the foamability and stability of foam discharging agent can substantially reduce, especially more than 100 DEG C
High-temperature stratum, foam can disappear within a few minutes caused by many foaming agents, not produce foam even.
During the field application of gas field, the high foam row containing oil environment in the market conventional products in the presence of gas well
Hydraulic art has a great influence so that can not form stable oil resistant foam carrier in the wellbore, and cause back pressure liter in lifting process
Height, therefore obvious foam drainage gas recovery effect can not be obtained.
And existing foam discharging agent has poor solubility property, foaming and foam stabilizing scarce capacity, or even the problem of can not bubble, no
It can meet that low cost, highly dissoluble, high temperature resistance, salt resistance, foaming and foam stabilizing ability significantly require simultaneously.
