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
Class phosphinylidyne-containing amine group quaternary surfactant has both bubble row and sterilizing function, and hydrophobic chain is to replace naphthalene nucleus, phenyl ring or natural oil
Hydrophobic patch in ester, the performance with very strong chlorine-resistant and condensate oil also have good corrosion inhibition.However due to dividing
Contain the amide group more sensitive to high temperature in minor structure, thus it is poor to 100 DEG C or more of gas well adaptability.China be from
Begin one's study in the year eighties in last century foam drainaging gas cutting process technology, and UT series is that more foam discharging agent is applied in domestic gas field,
UT series foaming water discharge agent and associated auxiliary products more than 20 are a at present, are suitble to the UT-11C of middle-deep well, ultradeep well
Anti- high salinity 250,000g/L, high temperature are up to 130 DEG C.
