Abstract:
Based on the data of core, drilling and logging, types of sedimentary facies of Shahejie Formation of Huanxiling Area in the west depression, Liaohe Basin were summarized; the relative single-factor comprehensive mapping method was firstly proposed to draw the plan of sedimentary facies in different sedimentary periods; sedimentary characteristics and evolution of Shahejie Formation were discussed. The results showed that there were 4 types of sedimentary facies, which included fan delta, sub-lacustrine fan, littoral-shallow lake and semi-deep and deep lakes, in Shahejie Formation of Huanxiling Area; fan delta sand body, which mainly developed in the gentle slope of the basin during the sedimentary period of Shahejie Formation, was the main reservoir sand body in Huanxiling Area; sub-lacustrine fan, which mainly distributed in the broad semi-deep and deep lakes environments, mainly developed during the sedimentary period of SQ3 and SQ4; compared with the traditional mapping method, the relative single-factor comprehensive mapping method could improve the precision significantly; cyclicity of vertical evolution of sedimentary facies in Shahejie Formation could be obviously divided into two transgressive cycles with the sedimentary periods of SQ2-SQ4 and the periods of SQ6 and SQ7, respectively; at the early stage of transgressive cycle, basin tectonic activity was relatively weak, and the depth of water was relatively shallow, so fan delta sedimentary widely developed, and sub-lacustrine fan sedimentary decreased; at the middle and late stages of transgressive cycle, basin tectonic activity was relatively strong, and the water deepened, so fan delta sedimentary decreased, and sub-lacustrine fan sedimentary increased significantly, and then the favorable reservoir sand body, which formed and developed widely, was one of the favorable reservoirs for the deep exploration in the west depression, Liaohe Basin.
