Background technology
Along with the Persisting exploitation in gas field, gas reservoir aquifer yield and water outlet gas well number are in the trend be on the increase, and Wellbore of Gas Wells hydrops and water outlet affect the gas well problem such as normally to produce and progressively manifest; Gas well dewatering makes single phase gas seepage flow change air water two phase fluid flow into, gas phase permeability is not only caused to reduce, consume producing energy in a large number simultaneously, the hydrops that can not carry in pit shaft reduces drawdown pressure, cause gas well low yield even to stop production, Gas well dewatering and pit shaft hydrops have become the major reason of restriction gas well deliverability.Along with going deep into of exploitation, gas well quantity is more and more and most of gas well belongs to middle stripper well, and this kind of well is because output is lower, stratum fluid is many and discontinuous himself fluid-carrying capability that causes is poor, and in well, hydrops is serious; Even for the well that production capacity is higher, because stratum fluid is many or the situation taking liquid difficulty has greatly also appearred in tubing string.The object of research foam drainage gas recovery is exactly to get rid of pit shaft hydrops, recovers the normal production of gas well.
The present invention, mainly for the problems referred to above, provides a kind of from the solid foam water discharge agent foamed, liquid carry over is large, froth stability is good.In existing foaming water discharge agent, Chinese patent CN102634327A Raw proportioning is mainly 95 ~ 105 parts, tensio-active agent, methylcellulose gum 3 ~ 7 parts, foam control agent 5 ~ 10 parts, wherein tensio-active agent is made up of according to weight ratio 1 ~ 2:1 ~ 2:1 ~ 2 soapberry extract, tetrahydroglyoxaline, Varion CDG-K; Chinese patent CN101492599B Raw proportioning is mainly triethylene tetramine 5 ~ 10%, diethylenetriamine 10 ~ 20%, oleic acid 10 ~ 30%, glacial acetic acid 2 ~ 10%, maleic anhydride 5 ~ 15%, the third acetic acid 5 ~ 10%; Proportioning raw materials of the present invention is tensio-active agent 40 ~ 50%, sodium carbonate 5 ~ 20%, SODIUM PHOSPHATE, MONOBASIC 40 ~ 55%, wherein tensio-active agent comprises dodecyl oxyethyl group sultaine 10 ~ 15%, ASEA(fatty alcohol sulfate single ethanol ammonium salt) 10 ~ 15%, LAS(linear alkylbenzene sulphonic acid) 5 ~ 10%, ABS(tetrapropylene benzene sulfonic acid sodium salt) 5 ~ 10%, AEC(laureth carboxylic acid sodium) 5 ~ 10%; Present component is novel, asepsis environment-protecting.
Summary of the invention
The object of the invention is to develop a kind of solid foam water discharge agent be applicable in Natural gas extraction production and preparation method thereof, make it have and meet water from features such as foaming, dissolve rapidly, froth stability is good, liquid carry over is large, for Natural gas extraction provides a kind of solid foam water discharge agent.
A kind of solid foam water discharge agent of the present invention, is made up of the raw material of following mass percentage content: tensio-active agent 40 ~ 50%, sodium carbonate 5 ~ 20%, SODIUM PHOSPHATE, MONOBASIC 40 ~ 55%.
In described tensio-active agent, each raw material accounts for the mass percent of solid foam water discharge agent and is: dodecyl oxyethyl group sultaine 10 ~ 15%, ASEA(fatty alcohol sulfate single ethanol ammonium salt) 10 ~ 15%, LAS(linear alkylbenzene sulphonic acid) 5 ~ 10%, ABS(tetrapropylene benzene sulfonic acid sodium salt) 5 ~ 10%, AEC(laureth carboxylic acid sodium) 5 ~ 10% compositions.
The effect of above-mentioned various feed composition:
Sodium carbonate and SODIUM PHOSPHATE, MONOBASIC play from foaming and shaping effect; Dodecyl oxyethyl group sultaine and AESA have higher foaming power and the compatibility of excellence; ASEA, ABS and LAS have superior foam stability energy; AEC has good excellent anti-salt and methanol tolerance ability.
Relative to prior art, beneficial effect of the present invention is:
1) solid foam water discharge agent preparation method of the present invention is simple to operation.
2) solid foam water discharge agent of the present invention has from the common function of producing bubble of both foaming and tensio-active agent, and make foaming abundancy, foaming aqueous rate is high, and liquid carry over is large.
3) solid foam water discharge agent of the present invention has the performance of excellent anti-salt, methanol tolerance, oil resistant.
4) solid foam water discharge agent of the present invention has good compatibleness, chemical reaction does not occur with gas, fluid component, and it is very high that test in place bubble lines up power.
