| 中文摘要:在沧州深部盐矿普查项目中，施工完成的ZK002孔，500～3290 m孔段进行取心工作。钻探过程中，设计了深、浅“双孔方案”，分别采用地质和石油钻探设备，将常规岩心钻探技术与钻井取心技术组合，实现了两类设备、不同取心工艺之间的优势互补，最终降低了施工风险、确保了钻孔质量、节约了施工成本、缩短了工期。 |

| Abstract:In Cangzhou deep salt mine survey project, coring in 500～3290m section of the completed ZK002 was carried out. Deep and shallow double-hole was designed and geological and petroleum drilling equipments were used respectively. The conventional core drilling technology and drilling coring technology were combined to realize the complementary advantages of 2 types of equipment and different coring processes, the construction risk reducing, drilling quality ensuring, construction cost saving and construction period shortening. |
