摘要
东濮凹陷桥口构造东翼的 Es33 和 Es43 亚段是该区主要的天然气储集层 ,发育三角洲前缘亚相的水下分流河道、河口坝及前缘席状砂等储层砂体 ,储层类型为低孔低渗及中孔低渗型。该区主要断层的活动结束较早 ,对来自中央隆起带两侧生烃洼陷 (前梨园洼陷及葛岗集洼陷 )的天然气具有较好的封堵性。综合该区烃源岩、储层特征、圈闭特征的分析认为 。
The Es 3 3 and Es 4 3 sub members in the east flank of Qiaokou structure, Dongpu depression are major gas reservoirs. Reservoir rocks including submerged distributary channel, mouth bar and frontal sand sheet sandbodies in delta front The types of the reservoirs are of both low porosity and low permeability and moderate porosity and low permeability The action of major faulted block ends earlier, which results in good sealing ability to the gas generated Qianliyuan and Gegangji sags on both sides of the area An analysis is put forward based on the source rocks and characteristics of reservoirs and traps, the obtained result shows that Litun antithetic roof faulted block and Yuhuangmiao graben are the favorable accumulation areas
