中国海洋石油总公司2015年8月24日宣布,由“海洋石油981”深水钻井平台承钻的我国首口深水高温高压探井已于我国南海顺利完钻。陵水25-1S-1井位于我国南海距三亚140 km海域。该井水深近千米,设计井深4 000 m,目的层压力系数为1.7~1.9,温度超150℃,属于典型的高温高压井。深水、高温、高压,是长期困扰我国南海油气勘
China National Offshore Oil Corporation announced on August 24, 2015 that the first deep-water high-temperature and high-pressure exploration well drilled in China by the Deep-water drilling platform “Offshore Oil 981” had been successfully drilled in South China Sea. Lingshui 25-1S-1 well is located in the South China Sea from China Sanya 140 km sea. The water depth of nearly kilometers, the design depth of 4 000 m, the target pressure coefficient of 1.7 to 1.9, the temperature over 150 ℃, is a typical high-temperature high-pressure wells. Deepwater, high temperature, high pressure, is long plagued China’s South China Sea oil and gas exploration
