摘要：

为明确富满地区中奥陶统一间房组颗粒滩类型及其分布，应用岩心、岩石薄片、碳同位素、测井、地震等资料，对其沉积相及其展布开展了研究。研究区一间房组沉积相类型可分为斜坡—盆地、台地边缘和开阔台地，后两者是颗粒滩的主要发育区；颗粒滩包括砂屑滩、鲕粒滩、生屑滩、过渡类型等，厚度占比普遍大于80%，部分井区大于90%，具浅颗粒滩化，其分布受快速海侵及缓慢海退背景下侧向迁移为主的沉积方式控制。开阔台地大面积分布的砂屑滩及生屑砂屑滩具备良好的储集性能，可作为下一步油气勘探的重要领域。

Abstract:

To clarify the types and distribution of grain shoals in the Middle Ordovician Yijianfang formation in the Fuman area of the Tarim basin, the sedimentary facies and distribution were studied using the core, rock thin section, carbon isotope, logging, and seismic data. The sedimentary facies of the Yijianfang formation in the study area can be categorized into slope-basin, platform margin, and open platform, with the latter two being the principal zones for grain shoal development. The grain shoals which include psammitic shoal, oolitic shoal, bioclastic shoal, and transitional types, generally account for over 80% of the formation thickness, or even over 90% in some well blocks. The distribution of these shallow grain shoals are primarily under the control of sedimentation processes represented by lateral migration in the setting of rapid marine transgression and gradual marine regression. The psammitic shoals and bioclastic-psammitic shoals extensively distributed in the open platform indicates excellent reservoir quality, and they will be significant targets for future petroleum exploration.

Key words: Tarim basin, Fuman area, Ordovician, Yijianfang formation, carbonate, grain shoal type, grain shoal distribution
