Description
Technical field
The present invention relates to the suds-stabilizing agent technical field, be specially a kind of white oil foam discharging agent that is applicable to Natural gas extraction.
Background technology
At present, the foaming water discharge gas producing technology has that less investment, cost are low, instant effect, enforcement influence advantages such as gas well ordinary production easily and not, thereby extensively adopted.Gas field had been carried out moisture gas well foaming water discharge gas production test first in 1980, and economic benefit and social benefit are very significantly.
The gas-condensate well development late stage is because the stratum pressure drop is big, and it is big that ground reveals pressure reduction, and the pit shaft hydrops has a strong impact on production capacity and causes abandonment pressure high, and ultimate recovery factor is low, and liquid discharging gas producing is the necessary means of later development.Therefore gas-condensate well is carried out the foam liquid discharging gas producing has prior meaning.Have foam discharging agent kind more than ten both at home and abroad; Be suitable for different hydrops gas reservoirs respectively, but they generally are applicable to stratum and the not high gas well of white oil content below 80 ℃, with the rising of envrionment temperature and the increase of white oil content; The latherability of foam discharging agent can reduce with stability greatly; Especially the high-temperature stratum more than 100 ℃ and white oil content greater than 20% gas well in, the foam that many pore forming materials produce can disappear in 1～2min, does not even produce foam.Along with the development of petroleum industry, choosing of the foam liquid discharging gas producing technology of gas-condensate well and foam discharging agent and confirming of construction parameter become the key factor of gas-condensate well foam liquid discharging gas producing technology.
For a long time, the foaming of nonaqueous phase solvent and surely steep the difficult problem of international scientific circle always.This product is big to the white oil content of pit shaft collection in the gas exploitation course of oil field, causes the pit shaft liquid collecting serious, to white oil different content in the hydrops; Develop condensate oil foam discharging agent BO; BG series utilizes Sweet natural gas to impact, and will contain the hydrops foaming of white oil; With foam or vaporific water and white oil are taken out of thereupon, solved the pit shaft hydrops phenomenon that causes by water and white oil.
Summary of the invention
The objective of the invention is: a kind of white oil foam discharging agent that is applicable to Natural gas extraction is provided, is used for producing a large amount of white oil fluid-discharge technology processes in Natural gas extraction.Adopt unique surfactant compound system, can high white oil content even the foaming fully under natural gas flow stirs of full white oil be formed spray flow, white oil and water are taken out of by air-flow more easily.
The technical scheme that the present invention adopts is: be applicable to the white oil foam discharging agent of Natural gas extraction, each weight percentages of components is:
AS 15～35%;
Amphoterics accounts for 20～30%;
Fluorocarbon surfactant 2～5%;
Suds-stabilizing agent 0.2～0.3%;
All the other water are that each component percentages sum is absolutely.
AS can be chosen a kind of of petroleum sodium sulfonate, sodium lauryl sulphate or sodium oleate.
Zwitterionics is the imidazoline type zwitterionics, belongs to 2-undecyl-N-hydroxyethyl-N-ethyloic tetrahydroglyoxaline.Consult: Feng Jincheng, Wen Shaoying, Zhao Erru, Qin Baoluo, the synergistic effect [J] of 2-undecyl-N-ethyloic-N-hydroxyethyl imidazole quinoline and AS, daily chemical industry, 2001, (1), 9-10.
The structure of fluorocarbon surfactant: sultaine fluorocarbon surfactant, alkyl chain length are consulted between C12～C18: the foaming properties research [J] of the sultaine fluorocarbon surfactant that people such as Wang Yanling write; The silicate circular; 2010,29 (2), 314-318; Synthetic and the performance study [D] of the alkyl hydroxy sultaine viscoelasticity tensio-active agent that Zhang Rongming writes, Northeast Petroleum University, 2007.
Suds-stabilizing agent can be chosen a kind of of non-ionic polyacrylamide (800-1200 ten thousand), Z 150PH or CMC 99.5.
Be applicable to the preparation method of the white oil foam discharging agent of Natural gas extraction:
(1) at normal temperatures and pressures, 50% of Total Water is added reaction kettle, add suds-stabilizing agent, stirred 0.5～1 hour, adding 50% remaining water, be stirred to evenly;
(2) AS, amphoterics, fluorocarbon surfactant are added reaction kettle, fully stirred 1～2 hour, mix, form foam discharging agent.
Be applicable to the method for use of the white oil foam discharging agent of Natural gas extraction:
Need not dilute when (1) using, directly coming into operation gets final product.Medicament adds concentration and can not coexist according to pit shaft hydrops white oil content and float in 1～3% scope.Muddy before using as finding, shake up and can use.
(2) applicable to the pit shaft discharge opeing of gas-condensate well in the Natural gas extraction, be particularly useful for white oil content>40% all can realize discharge opeing.
Beneficial effect of the present invention: the present invention is applicable to the white oil foam discharging agent of Natural gas extraction, can in 20～80 ℃ of TRs, stablize foaming, has good anti-salt property, and can resist methanol content < 20% interference.The principle of foam liquid discharging gas producing technology is through in oil pipe or oil jacket annular space, injecting foam discharging agent, and the shaft bottom hydrops, generates a large amount of low density and contains liquid foam by the stirring of natural gas flow with after foam discharging agent contacts, and is carried to ground with air-flow from the shaft bottom.In addition, foam discharging agent impels the pit shaft hydrops to form foam also through effects such as dispersion, infiltration, drag reduction, washings, discharges with air-flow, reaches the exploitation gas field of highly economical.After foam discharging agent is added to the gas well of gas-condensate well band liquid ability, discharge opeing there is following effect:
(1) transformation of fluidised form, foam discharging agent utilize foam discharging agent and white oil, aqueous systems generation emulsifying effect after adding in the well, and the surface tension of the profit system after the emulsification reduces, and the profit system is prone to disperseed by air-flow, become spray flow or ring film stream.
(2) improve the bubbling height of bubble fluidised form, thereby make the bubbling height arrive not the gas well of well head, but can arrive well head from overflowing.
(3) slippage that has reduced air-flow is lost.After adding people's foam discharging agent, gas is dispersed in the liquid film with blister, forms a kind of reticulated polymer foam structure, and gas and oil (water) moves simultaneously, can reduce the slippage loss.
Form simply, cheap, can under full white oil is formed, foam, and foaming power is strong, froth stability is good, can resist the subsurface environment under high salinity, the high temperature.And can satisfy and contain different white oil content under the gasser and regulate prescription and form foam discharge opeing demands.
