摘要
镇巴区块台地边缘颗粒灰岩储层是重要的勘探层位。根据构造演化背景，通过沉积演化及沉积相分析，认为台地边缘亮晶鲕粒灰岩、亮晶砂屑灰岩储层的展布严格受有利沉积相带所控制，随着城口海槽的成生、发展、萎缩，台缘鲕滩不仅向广海（北大巴）方向发生了迁移，而且发育层位逐步抬高，具有明显穿时性特征。镇巴区块铁溪万源区带飞一段一飞二段发育厚层状鲕粒坝储集层，单层厚度为22~40m，分布较为稳定，是优质储集层。
The reservoirs of grain limestone developed on the platform edg southwest of China are the important exploration strata. According t background and by the analysing the sedimentary evolution and facies, th distribution of the reservoirs of sparry oolite limestone and sparry arenite e of the Zhenba area in the o the structural evolution e authors consider that the limestone developed on the platform edge is controlled strictly by the sedimentary facies belts. As the generation, development, shrinkage of the Chengkou Trough, the oolitic shoals developed on the platform edge migrate toward open sea （northern Daba Mountain） and the place where they developed elevates with an obvious diachronous feature. The article points out that the reservoirs of thick oolitic bars develop in Member 1 and 2 of the Lower Triassic Feixianguan Formation in the Tiexi-Wanyuan belt in the Zhenba area, with a thickness of 22 ~ 40 m for a single stratum and a stable distribution, and are the qualified reservoirs in this area
