永乐油田肇293区块位于三肇凹陷永乐向斜东翼,开发目的层为葡萄花油层。由于储层薄、物性差、同层较发育,且区块内断层较为发育等开发矛盾,截止到2010年区块内低产井、长关井比例已占总井数的75.7%,针对这一情况,我们开展了对肇293低效注采区块的治理,以提高区块内油水井的利用率及储层动用程度。
The Zhaoqing block of Yongle Oilfield is located in the east wing of the Yongle syncline in the Sanzhao depression, with the purpose of developing the Putaohua oil layer. Due to the thin reservoir, poor physical properties, the same layer is more developed, and more fault development within the block and other development contradictions, as of 2010 low production wells within the block, the proportion of Changguan wells accounted for 75.7% of the total number of wells, for this In the circumstances, we carried out the treatment of low-efficiency injection-production blocks in Zhaoxing 293 to improve the utilization rate of oil and gas wells and the utilization of the reservoir.
