Description
Technical field
The present invention relates to a kind of solid foam water discharge agent composition and preparation method and applications, especially a kind of high temperature is high
Salt deep-well solid foam water discharge agent composition and preparation method and applications.
Background technique
With the reinforcement of gas-field exploitation dynamics, gas field is discharged the critical issue normally produced at gas well is restricted.Foam row
Hydromining gas is a kind of drainage gas recovery that recent domestic rapidly develops, simple, easy for construction, at low cost with equipment,
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 foam discharging agent generates the foam with certain stability under the agitation of air-flow.The liquid phase that deposition is slipped in pipe becomes steeping
Foam changes the relative density of lower curtate bit stream body in managing, and quantity-produced gas phase displacement foam flows out pit shaft, so that well inner product be discharged
Liquid achievees the purpose that water pumping gas production.
The development of foreign countries' foam discharging agent since the eighties of last century sixties, multiselect sulfonate, benzene sulfonate, alkyl phenol are poly-
The surfactants such as ethylene oxide ether.Recompounded multielement system is mostly used greatly with foam discharging agent to current water pumping gas production, it is single in order to enhance
The stability of foam is usually additionally added the auxiliary agents such as alkali, alcohol, polymer, alkanolamide in formula and forms strengthening foam.
US7122509 reports a kind of high temperature foam discharging agent formula, and the Research Thinking neutralized using anionic surfactant plus amine is improved
The heat resistance of system.US20120279715 reports the aerated fluid that gas recovery in a kind of gas well increases oil yield, is one
