不压井带压作业就是利用特殊的修井设备,在油、气、水井井口带压的情况下实现管柱的安全、无污染起下作业。它能够有效地解决高压水井、自喷油井、新射孔和压裂井的作业难题,提高注水时效和水井利用率,大大减少油层污染,避免因压井对地层产生的伤害,进而提高油井的产能。目前,国际上正在广泛推广和应用带压作业技术,但该项技术在国内石油行业刚刚起步。 Do not kill with pressure operation is the use of special workover equipment, oil, gas, water wellhead with pressure to achieve the safety of the string, pollution-free operation. The utility model can effectively solve the operating problems of high pressure water wells, self-injection wells, new perforations and fracturing wells, improve water injection aging and water well utilization, greatly reduce oil layer contamination, and avoid damage caused by killing wells and thereby improve well Production capacity. Currently, the international community is widely promoting and applying pressurized operation technology, but the technology has just started in the domestic oil industry.
