小直径管+泡排和高压气举工艺对于产水气井都能够有效的起到排水采气的作用,但是对于积液停产或者水淹气井,使用单一的排水采气工艺并不能使积液停产井恢复产能。针对此种情况,本文在比较分析了这两种工艺的优缺点后,将两种工艺结合为一种复合工艺,同时采用高压氮气进行气举,研究了小直径管+泡排+氮气气举的复合复产工艺原理及适用条件,并通过现场试验证明,该工艺能够起到复产的作用。
Small-diameter tube + bubble row and high-pressure gas lift process can effectively play the role of drainage and gas production wells, but for liquid production stoppage or flooding gas wells, the use of a single drainage gas production process does not stop the effusion Well recovery capacity. In view of this situation, after comparative analysis of the advantages and disadvantages of these two processes, combining the two processes into a composite process, and using high-pressure nitrogen for gas lift, the paper studies the effects of small diameter tube + bubble row + nitrogen gas lift Compound compound process principle and applicable conditions, and through field tests to prove that the process can play a role of double production.
