Description
Technical field
The invention relates to a kind of foam lifting chemical agent dilution, its preparation method and application thereof.
Background technology
In foam drainage gas recovery technical process, conventionally foam lifting chemical agent is diluted to certain proportion, dense to preventSpend when large loss too much. When ground construction environment temperature is higher at the scene, conventionally make dilute with water, if but use in the winter timeWhen water dilution, the phenomenon that can freeze at low temperatures, is difficult for injecting.
Because surface line is for a long time under low temperature environment, in variation place of surface line pipe diameter size, easily form hydration, there is the stifled phenomenon of ice in thing, has disturbed daily production.
In addition, in formation water, chloride ion content is often higher, can produce corrosion in tubing and casing wherein to long period of soaking and doWith; In order to solve the etching problem of tubing and casing, conventionally inject corrosion inhibiter, some corrosion inhibiter tends to disturb the foaming energy of blowing agentPower. Therefore need one to address the above problem simultaneously, and foam lifting that can phase mutual interference between each chemical agent in componentLearn dilution agent liquid. Special proposition technical scheme of the present invention.

On the other hand, the present invention also provides the preparation method of described foam lifting chemical agent dilution: described method bagDraw together following steps: take sodium molybdate, orthophosphates and zinc sulfate, then add successively water, propane diols, finally 45 DEG C of conditionsUnder, at the uniform velocity stir and form uniform mixing material with rotating speed 200rpm.
Again on the one hand, the present invention also provides the application of described dilution in dilution gas well foam lifting chemical agent.
Wherein the ratio of preferred dilution of the present invention and gas well foam lifting chemical agent is weight ratio 4～6:1.
Wherein further preferred described gas well foam lifting chemical agent is foam discharging agent.
Another aspect, the present invention also provides application foam lifting chemical agent diluted gas well foam of the present inventionThe method of lifting chemical agent.
According to method of the present invention, it is characterized in that the ratio of described dilution and gas well foam lifting chemical agentFor weight ratio 4～6:1.
According to method of the present invention, it is characterized in that, described gas well foam lifting chemical agent is foam discharging agent.
In sum, the invention provides a kind of foam lifting chemical agent dilution, its preparation method and application thereof. ThisBright dilution tool has the following advantages:
1, anti-low temperature, in the time of subzero 40 DEG C, phenomenon can not freeze.
2, dilution blowing agent has certain synergy to the foamability of blowing agent simultaneously.
3, prevent that surface line generation ice is stifled.
4, tubing and casing is had to certain corrosion inhibition.
5, toxicity is little, and production safety hidden danger is little.
