摘要
潜江凹陷潜江组粒屑碳酸盐岩性主要发育鲕粒石灰岩、砂屑灰岩、泥晶砂屑云岩、藻团块灰岩等。研究认为,其沉积主要受风成湖浪和湖流以及古地形控制。依据古地形、水动力等分析,探讨了其沉积模式。分析化验资料统计表明,该类岩石主要发育粒间溶孔,有很好的储油气性,是江汉油田今后勘探的重点目标之一。
The grained Carbonate rocks of Qianjiang Formation in Qianjiang Sag can be divided into oolitic limestone,sand-clastic limestone,mud-crystal sand-clastic dolomite,alga-gobbet limestone etc.and its sediment is controlled by lake-wave,lake-flow and landform.The sedimentary patterns are discussed based on the analysis of palaeo-landform,hydrodynamics.Analytical data statistics show that intergranular dissolved pores are grown in the rocks,it is a good reservoir,which is one of important target zone for future exploration in Jianghan Oilfield.
