The paper summarizes the main technical characteristics of cementing operation in quick drilling project for SZ 36 - 1J Area in Bohai Sea. This is cluster drilling project with average drilling depth of 1876m, average well construction period of 3. 71 days and total footage of 28140 m. In the cementing operation, it is first time to adopt three new techniques; surface casing cementing operation without drilling rig, simplex and double (packers) seal cementing for long barehole interval and one~ step displacing...

The paper summarizes the main technical characteristics of cementing operation in quick drilling project for SZ 36 - 1J Area in Bohai Sea. This is cluster drilling project with average drilling depth of 1876m, average well construction period of 3. 71 days and total footage of 28140 m. In the cementing operation, it is first time to adopt three new techniques; surface casing cementing operation without drilling rig, simplex and double (packers) seal cementing for long barehole interval and one~ step displacing of corrosion inhibitor. Ten items of key techniques are utilized during cementing the oil layers, so that the cementing quality is guaranteed, the operation efficiency is improved and the qualification rate of oil layer cementing is up to 100%.

本文总结了渤海绥中36—I J区快速钻井中固井作业的主要技术特点。该丛式井钻井项目的平均井深 1876 m,平均建井周期 3.17 d,15口井总进尺 28 140m。在固井作业中,首次使用了无钻机时间固表层作业、长裸眼单级双封固井和防腐液一次替入等三项创新技术,油层套固井采取了十项关键技术,保证了作业质量,提高了作业效率,油层固井质量一次合格率达到100%,质量全优。

Multi - interval fracturlng techn[que in horizontal well includes two methods: casing distributary fracturing and double - packer- single - stlcking fracturing. This paper introduces the technical principle, design principle, consideration factors of tools systems of these two methods, analyzes the applicatlon effect of them ln three wells. The test shows that casing distributary fracturing is safe in construction, can be carried out in large displace-ment and high sand ratio. can increase productivity 1argely, and is the optimum fracturlng method for horizontal well. The characteristics of this technique is to determine the fractur-ing project at the same time of compiling completion project, it requires that several intervals are fractured safely at one tlrne in a longer well interval. As one of the standby techniques,double -packer-single-sticking fracturlng is mainly used for potentiallties tapping at latter stage of exploltation.

水平井多段压裂技术包括套管分流压裂和双封隔器单卡压裂两种方法。介绍了两种方法的工艺原理、设计原则、工具系统的考虑因囊等,并对3口升的应用效果进行了分析。试验证明会管分流压裂施工安全,可大排量高砂比施工地产效果明显,是水平井压裂的首选方法。该技术的特点是在制定完并方案的同时确定出压裂方案,它要求在校长的井段内一次安全完成多个层段压裂施工。双封隔器单卡压裂做为一种储备技术,主要用于开来后期的挖潜。

Retrievable double-packer recovery string technology is a new one developed upon needs for reperforation, recovery of another payzone, machinery blocking water and some other stimulation in deep wells. The paper mainly introduces the specifications, principle, and application of the technology, and also gives some opinions to improve the technoloy constantly.
