现代综合配套优质快速钻井技术在辽东湾J区丛式井的应用

从技术和管理两个方面介绍了渤海SZ36-1-J区15口丛式开在钻井中全面推广和应用九项先进钻井技术以及适合J区特点和要求的五项创新技术。15口丛式井平均井深1878m,平均建井周期3.71d。其中最快的J7井井深1795m,钻井周期2.60d;J16井井深2058m,钻井周期3.72d;J11井井深1730m,平均日进尺640m;J10井井深1660m,平均机械钻速132.83m/h,其钻井速度和钻井周期均达到了目前海总同类井的最高水平,为开发边际油田、节约钻井费用、减少开发投资提供了保证。

APPLICATIONS OF MODERN COMPREHENSIVE OPTIMIZED DRILLING TECHNIQUES OF CLUSTER WELL IN J-REGION IN LIAODONG GULF

The nine advanced drilling techniques and the five newly developed techniques specially for this region applied in a cluster of 15 wells drilled in SZ36- 1 -J region,Bohai Golf were described. The average depth of the 15 cluster wells was 1 878m, the average well construction cycle was 3. 71d. Some of them created the best engineering records.Like 2. 55 days of well construction cycle in J7 well with a depth of 1 795 m, 3. 72 days in J16 well of final depth 2 058 m, average daily footage of 640 m in J11 of final depth 1730 m and average penetration rate of the 15 wells 132. 83 m/h. The penetration rate, drilling rate and well construction term attained the domestic highest record for the same kind of wells.
