Abstract
TUHA oil field has been putting into production in 1991, with the development of TUHA oil field,the reservoir pressure is dropping off,the gas oil ratio(GOR) is quickly rising.Especially,large quantities of high GOR well appeared from the Wenmi oil field.The artificial lift of sucker rod pump and electric pump adjustability is dropping off.The gas reservoir of TUHA oil field is gas condensate reservoir,the gas reservoir is deep,single well production is low,gas slippage loss is major,a large quantity of liquid is being assembled in the bottom,the gas production rate is descent.Using foam drainage is costly.Whereas,the plunger gas-lift by crude gas is very good.Therefore we developed the plunger gas-lift by crude gas technology,and the technology has been adapted field experiment,the effect is very good.The plunger gas-lift by crude gas technology is a resultful artificial lift technology for the high GOR well and the gas well drainage.
