针对洼38块进入高轮次吞吐、高采出程度、剩余油分布日趋零散现状,以增加可采储量、降低油田递减为核心,在精细油藏描述基础上,通过进一步优化低效吞吐井设计,加强沙三段油层汽驱综合调整,开展东三段油层一注多采试验和剩余油挖潜,实施东二段油层二次开发,建立了适应吞吐末期“有效开发”的新思路,使油田开发水平不断提高。
According to the present situation of high-round throughput, high-recovery rate and remaining oil distribution in Wa38 block, the recoverable reserves are increased and the decrement of oil field is the core. Based on the detailed reservoir description, by further optimizing the design of low-efficiency stimulation wells , Comprehensive adjustment of steam flooding and flood control in the third member of Shahejie formation was carried out, a multi-injection test of one injection in the third member of the Third Member of the Third Member and potential tapping of remaining oil were carried out to implement the secondary development of the second member of the second member of the Second Member of the East Third Ringou Formation and a new mentality of “effective development” So that the level of oil field development continues to increase.
