摘要:
为解决南海西部窄安全密度窗口地层钻井中易发生井漏、井涌甚至井喷等井下故障的问题，通过研究超高温高压复杂地层压力预测监测技术、钻井液随钻堵漏技术、井下当量循环密度预测与监测技术、抗高温钻井液、超高温高压固井技术，形成了适用于南海西部的窄安全密度窗口超高温高压钻井技术。该技术在乐东区域的7口超高温高压探井进行了应用，钻井成功率达到100%，井下故障率显著降低，与应用前的同类型井相比，钻井生产时效平均提高了21%。这表明，窄安全密度窗口超高温高压钻井技术可以解决南海西部安全密度窗口窄导致的问题，可为深水高温高压领域的勘探开发提供技术支持。
Abstract:In order to solve lost circulation, well kick and even blowout caused by narrow safety density window in the western South China Sea, a great effort has been made in studying technologies of the pressure prediction and monitoring in ultra-HTHP complicated formation, the drilling fluid plugging while drilling, the prediction and monitoring of downhole equivalent circulation density, and the high temperature resistant drilling fluid and utra-HTHP cementing. As an achievement, the narrow safety density ultra-HTHP drilling technology suitable for the western South China Sea has been developed. This technology has been applied in seven ultra-HTHP exploration wells in Ledong area, and the occurrence of downhole problems has been significantly reduced. Compared with the same type of wells prior to applying this technology, the average drilling time efficiency increased by 21% and the drilling success rate reached 100%. This showed that the ultra-HTHP narrow density window drilling technology could solve the problems caused by the narrow safety density window in the western South China Sea, and provide technical support for the exploration and development of high temperature high pressure deep water reservoirs.
