摘要
针对井筒承压能力低,又无法实施有效堵漏的工况提出了高压盐水放喷卸压技术,采用合理放喷卸压方法,适当降低高压盐水层压力,在溢流与漏失这对矛盾中找到合适的压力平衡点,实现有利于井控安全的井筒状态;同时完成了井控装备改进方案,及放喷卸压基本流程,为高压盐水放喷卸压技术工程应用奠定了基础。
In this article, aiming at the working condition of wellhole which has low pressure-bearing and plugging can not be implemented effectively, The pressure relief method is used to reduce the pressure of high pressured saltwater layer, the appro- priate pressure balance point is found between the contradiction of overflow and leakage ,which can help to realize wellbore sta- tus benefiting wellbore control safety. The improvement program of wellbore control equipment and pressure relief process are finished,which establishes the foundation for the pressure relief technology of high pressured saltwater.
