摘要:

通过对饶阳凹陷留107区块断层-岩性油藏的解剖,明确了该类型油气藏的成藏主控因素。留107区块位于饶阳凹陷中部富油气的肃宁构造与大王庄构造的结合部,为东西两侧受断层夹持的NE向单斜构造,储油层为古近系沙河街组一段上亚段—东营组三段三角洲前缘河口坝、分流河道及河流相砂体。留107区块断层-岩性油藏富集程度高,开发效果好,其成藏与富集的关键因素是:①区块西北侧低部位断层在主生排烃期(馆陶组—明化镇组沉积期)持续性活动,沟通了油气源,区块东、西两侧高部位断层在主生排烃期前就停止了活动,起到封挡作用;②小于35%的中低砂/地比和断层与砂体的走向斜交,有利于断层-岩性油藏的形成和富集,并形成平面上多个油藏、纵向上多套层系的成藏特征;③区域性稳定的盖层控制了油气的主要聚集层位。

Abstract:

The major controlling factors of reservoir accumulation was clarified by performing an analysis on the fault-lithologic reservoir of Liu 107 block, Raoyang Depression. The Liu 107 block is located at the junction of hydrocarbon-rich Suning structure and Dawangzhuang structure in the central part of Raoyang depression. This block shows a NE-trending monocline structure held by faults on both east and west sides. The reservoirs consist of delta-front mouth bar, distributary channel and fluvial facies sand bodies in the Upper Member 1st of Paleogene Shahejie Formation and the Member 3nd of Dongying Formation. The fault-lithologic reservoirs of Liu 107 block are characterized by high enrichment degree and favorable development effect. There are three key controlling factors of accumulation and enrichment. First, the faults at the lower part on the northwest side of this block were active continuously during the major hydrocarbon generation and expulsion period (Guantao-Minghuazhen Period), by which the hydrocarbon sources were connected. Then the faults at the upper part on the both east and west sides of the block stopped acting before the main hydrocarbon expulsion stage and had a role in sealing. Second, the mid-low ratio between sandstone and stratum thickness (<35%) and the oblique intersection between faults and sand bodies were favorable for the formation and enrichment of fault-lithologic reservoirs with the characteristics of multiple reservoirs on the horizontal level and multiple oil-bearing series on the vertical level. Third, the main horizons of oil and gas accumulation were controlled by regional stable cap rocks.

Key words: fault-lithologic reservoirs, key controlling factors, rifted basin, Raoyang sag, Upper Member 1st of Shahejie Formation, Member 3nd of Dongying Formation, Liu 107 block
