摘要: 塔河油田顺南区块地处塔克拉玛干沙漠腹地，目的层属于高压气层，前期顺南某井在蓬莱坝组钻遇高压储层后出现井控险情，地面管汇及表层套管多处刺漏。为确保高压气井的安全钻进，从井控工艺及地面设备进行优化，优选关键配件及地面管汇配套组合，为该区高压气井的安全钻进提供理论及实际依据。

Abstract: The Shunnan block locates in the center of the Taklimakan Desert, which has many high-pressure gas reservoirs. Well control accidents have occurred when drilling in the Penglaiba Formation in a high-pressure re-servoir of the Shunnan X well, causing washouts at control system and surface casing. In order to ensure safety while drilling high pressure gas wells, we optimized well control technology and ground equipment, and preferred key fittings and ground pipe manifold matching combinations, which provided theoretical and practical basis for the safety drilling of high pressure gas wells in this area.
