濮城油田南区沙二下储层研究及应用

Discussion of Observation of Hu-63 Reservoir Bed and the Potential Direction of Oil Residue

濮城油田南区沙二下油藏是一个被断层复杂化的断块型油藏。目前已进入开发中后期 ,含水高、递减大 ,措施有效率低是其重要特点。针对这一现状 ,我们对南区沙二下沉积微相、微构造及砂体空间展布几何形态进行了精细研究 ,绘制各类地质图件 91幅。在该成果的基础上 ,我们布署了一批效果较好的调整井 ,年累产油达 2 0 60 7吨 ,投入产出比为 1∶ 6.

Strata of Es2X of NanQu in PuChemg oil field is a fault-block oil reservoir which is complexed by faults. Now it's in the late stage of producing. The primary characters are the high water cut, the rapidly decreasing and the lower effective efficiency. Aimming at such cases, we studied the structures, the sedimentary facies, the geometric shape of sands spreading, and so on. With that, we have compilated 91 geologic drawings. In the foundation of this achievement, We have deposited several adjusting wells, and achieved good efficiency. The annual increment of oil production is 20607t, the input-output ratio is 1∶6.59
