| Abstract: | 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. |
