Applicable well depth range is big, does not influence the advantages that gas well normally produces.Foaming water discharge is exactly to pass through oil pipe or tubing and casing annular space to well
Interior injection foaming water discharge agent generates the foam with certain stability under the agitation of air-flow.The liquid phase that deposition is slipped in pipe becomes
For foam, change the relative density of lower curtate bit stream body in managing, quantity-produced gas phase displacement foam flows out pit shaft, so that well be discharged
Interior hydrops, achievees the purpose that water pumping gas production.
The development of foreign countries' foaming water discharge agent since the eighties of last century sixties, multiselect sulfonate, benzene sulfonate, alkyl
The surfactants such as phenol polyethenoxy ether.Recompounded multielement system is mostly used greatly with foaming water discharge agent to current water pumping gas production, in order to
Enhance the stability of single foam, the auxiliary agents such as alkali, alcohol, polymer, alkanolamide are usually additionally added in formula and form strengthening foam.
US7122509 reports a kind of high temperature foam draining agent prescription, the Research Thinking neutralized using anionic surfactant plus amine,
The heat resistance of raising system.US20120279715 reports the aerated fluid that gas recovery in a kind of gas well increases oil yield,
It is that a kind of phosphinylidyne-containing amine group quaternary surfactant has both bubble row and sterilizing function, hydrophobic chain is to replace naphthalene nucleus, phenyl ring or day
Hydrophobic patch in right grease, the performance with very strong chlorine-resistant and condensate oil also have good corrosion inhibition.However by
Contain the amide group more sensitive to high temperature in molecular structure, thus it is poor to 100 DEG C or more of gas well adaptability.China
It is the foam drainaging gas cutting process technology that begins one's study from the year eighties in last century, patent CN102212348A discloses a kind of resistance to
Salt, methanol tolerance foaming water discharge agent, each component content by weight percentage are as follows: Cocoamidopropyl betaine 20~40%, oxidation
Amine 45~65%, alpha-alkene sulfonate 5~20%, triethanolamine 5~15%, fluorocarbon surfactant 0.2~2%, methanol 0~
5%, it can be resistant to salinity up to 180,000, but the agent contains fluorocarbon surfactant, not only cost greatly improves and to environment shadow
Sound is larger.UT series is domestic gas field using more foaming water discharge agent, at present UT series foaming water discharge agent and associated
Auxiliary products more than 20, be suitble to the anti-high salinity 250 of UT-11C of middle-deep well, ultradeep well, 000g/L, high temperature are up to 130 DEG C.
Summary of the invention
The technical problem to be solved by the present invention is to existing high temperature and high salt deep-well gas well, hydrops is excessive in the process of development,
The problem of leading to the gas well underproduction or even stop-spraying, a kind of method using foaming water discharge agent composition liquid discharging gas producing is provided, especially
A kind of method that temperature-resistant anti-salt uses foaming water discharge agent composition liquid discharging gas producing, is applied to high temperature and high salt deep-well, can efficiently take liquid,
With good heat-resistant salt-resistant performance, frothing capacity and fluid-carrying capability.
