摘要
ＱＨＤ３２—６—４井是渤海石油公司在秦皇岛３２—６构造钻的１口评价井，在该井松散的储层进行了连续系统取心。共下取心工具 ２６次，取心总进尺２０５．７１ｍ，收获岩心１６８， ２９ｍ，平均收获率８１．８１％，达到该区块取心收获率的最高点。文中介绍了系统取心的施工过程，通过详细分析取心的各个技术环节，总结出松散地层取心经验。
The Well QHD32 - 6 - 4 is an evaluation well drilled on Structure 32 - 6 in Qinhuangdao by Bobal Oil Company. The continuous systematic coring is done in the unconsolidated formation of the well. The coring tool is tripped in 26 times, with total coring footages of 205. 71m, recovered core of 168.29m and the average core recovery of 81.81 %, the highest in the block. The paper presents the operational process of systematic coring, and sums up the experience of coring in the unconsolidated formation from analyzing each technical links in the coring.
