井下作业过程中,落地污油污水经常污染环境,造成地表水及土壤被污染,地表植被破坏等情况。以往检泵作业所采用的地面井控设备和井下防喷工具,存在很大的局限性,尤其是环保效果差,已经不能满足现阶段的井控环保要求。介绍井控环保的技术现状,针对存在的问题,近年开展了五项井控环保新技术的应用,取得明显效果,为检泵作业实现井控环保目标提供技术保障。
Downhole operations, the floor polluted sewage often pollute the environment, causing surface water and soil contamination, surface vegetation damage and so on. In the past, the ground-based well control equipment and downhole blowout preventers used in the operation of the inspection pump possessed great limitations. In particular, the environmental protection effect was poor and the well control environmental protection requirements of the current stage were no longer met. In view of the existing problems, the application of five new well control environmental protection technologies has been carried out in recent years, which has achieved remarkable results and provided technical support for the well control and environmental protection of pump operation.
