Abstract
The invention relates to a high-temperature foam scrubbing agent for drainage gas recovery. The agent comprises the following components in parts by weight: 10-15 parts of sodium lauryl sulfate, 2-5 parts of alkyl glucoside, 15-18 parts of AES ( Alcohol Ether Sulphate), 20-25 parts of sodium lauryl sulfonate, 5-10 parts of biosurfactant and 27-48 parts of water. The high-temperature foam scrubbing agent has very high thermal stability and high foamability.
Description
Technical field
The present invention relates to a kind of prescription of carrying out the foaming water discharge gas production in the gas well exploitation, particularly a kind of water pumping gas production high temperature foam discharging agent.
Background technology
The foaming water discharge gas production is a kind of water pumping gas production technology that develops rapidly both at home and abroad in recent years, has that equipment is simple, easy construction, cost are low, be suitable for the well depth scope greatly, does not influence advantages such as gas well ordinary production.It is that foam discharging agent is injected moisture gas well, after making shaft bottom liquid and foam discharging agent contacting, by the stirring of natural gas flow, generates a large amount of low density resistance aqueous foams, foam take water with air-flow from the shaft bottom to ground, reach the purpose of stable yields, volume increase and prolongation its flush stage.At present, domestic foam discharging agent generally is applicable to 70 ℃ with sub-surface, raises with envrionment temperature, and the latherability and the stability of foam discharging agent reduce greatly, and many foam discharging agents can occur crosslinked and lost efficacy at high-temperature stratum.Generally speaking, it is bigger that the whipability of foam discharging agent and thermostability are influenced by bottom temperature, along with raise its use properties of temperature descends, often do not reach the effect of water pumping gas production.
Along with the exploitation of gas well, the pit shaft hydrops is serious, in order to improve gas well output, discharge the shaft bottom hydrops.Foaming water discharge gas production method is the water pumping gas production method of a kind of economy height, efficient height, easy construction, is used widely in the gas field.
The situation that can not be fit to high temperature, high salinity and high CONDENSATE OIL AND GAS well at a large amount of foam discharging agents simultaneously, be combined with the Development characteristics that aqueous vapor is hidden, theoretical and whipability, foam stability theory according to tensio-active agent, employing orthonormal design of experiments method has been developed a kind of novel foam water discharge agent on the basis of experiment.
Summary of the invention
In order to overcome the defective of prior art, the object of the present invention is to provide a kind of water pumping gas production high temperature foam discharging agent, have very high thermostability, very strong whipability.
In order to achieve the above object, technical scheme of the present invention is achieved in that
A kind of water pumping gas production high temperature foam discharging agent, its components in mass portion number is: sodium lauryl sulphate 10-15 part, alkyl glycoside account for 2-5 part, and AES accounts for 15-18 part, and sodium laurylsulfonate accounts for 20-25 part, and bio-surfactant accounts for 5-10 part, and water accounts for 27-48 part.
Described AES is a fatty alcohol polyoxyethylene ether sulfate.
Described bio-surfactant is by mass fraction 30% glycerin fatty acid ester, and 20% lipid acid sorb is smooth, and 20% polysorbate and 30% stearic acid are formed.
High temperature foam discharging agent of the present invention has following outstanding advantage:
(1) this foam discharging agent has good lathering property under the condition of high temperature, high salinity, and latherability is strong, and froth stability is good, and Heat stability is good reaches as high as 350 ℃.
(2) foam discharging agent does not have corrosion to tubing, test shows, and in the time of 70 ℃, the corrosion speed of this foam discharging agent is 0g/ (m
2.h), safe and reliable, the stratum there is not injury.
(3) this foam discharging agent not only has good compatibleness, also has good corrosion inhibiting ability, the protection oil reservoir.
(4) this foam discharging agent is applicable to that the deep-well of high temperature, high salinity condition carries out foaming water discharge gas production construction operation.Help and adopt respond wellly, it is strong to take outlet capacity, has played to reduce oil jacket pressure reduction, improve the effect of taking outlet capacity.
