海上稠油热采井口高温BOP保护工艺及应用

BOP process for high temperature of wellhead in offshore heavy oil thermal recovery

渤海海上油田XX井由于井口温度过高,导致蒸汽泄漏,无法进行高温钢丝作业,无法对井下温度、压力及干度分布进行分析从而影响了对整个蒸汽吞吐热采效果的评价。针对这一问题,通过对工艺流程的改进与设备完善,满足了海上蒸汽吞吐对高温测试设备的要求,取得了测试数据,为海上蒸汽吞吐发展提供了技术保障。

The high wellhead temperature in XX well,Bohai oilfield has caused the leakage of steam,which hinders the steel wire operation and analysis of the temperature,pressure and dryness distribution of down hole, theevaluation on the offshore steam stimulation thermal recovery is affected consequently. This paper describes the modification for the process and facilities to meet the requirements of the high temperature test equipment used for offshore steam stimulation. The test data is obtained to offer technical guidance for development of the technology.
