孔雀亭地区平湖组油气输导体系定量表征及应用分析

Quantitative Characterization and Application Analysis of Hydrocarbon Transport System of Pinghu Formation in Kongqueting Area

输导体系作为油气运移的主要通道，对油气的分布具有重要的控制作用。该文主要运用定量方法落实了孔雀亭平湖组不同地区断裂垂向、侧向及砂体的输导效率，在此基础上依据断层倾向、砂体倾向、构造特征等将断砂组合划为六种复合输导系统，其中顺向断砂、反向断砂为主要的复合输导系统。该文通过对断砂组合类型、油气运移方式及分布情况的研究，总结得到孔雀亭地区四种类型的输导聚集模式，分别为垂侧强输-下盘聚集、垂侧强输-上盘聚集、垂侧中输-上盘聚集、主侧弱输-上盘聚集。该研究对孔雀亭目标评价及优选具有一定的借鉴意义。

As the main channel of oil and gas migration, the transport system plays an important role in controlling the distribution of oil and gas. In this paper, the quantitative method was mainly used to analyze the transport efficiency of vertical and lateral faults and sandstone in different regions of Pinghu Formation in Kongqueting area. On this basis, the combination of fault and sand can be divided into six types of compound transport system according to dip of fault, tendency of sand body and structure characteristic, among which forward fault and sand body combination and inverted fault and sand body combination are the main compound transport systems. Through the studying of the combination of fault and sand, the migration mode and distribution of oil and gas, four types of transport and aggregation modes in Kongqueting area have been summarized. It includes vertical and lateral strong transport and oil-gas accumulated in the fault footwall, vertical and lateral strong transport and oil-gas accumulated in the upper wall, vertical and lateral medium transport and oil-gas accumulated in the upper wall, main lateral weak transport and oil-gas accumulated in the upper wall. This study has certain referential significance for the target evaluation and optimization of Kongqueting area.
