Reservoir Architecture Analysis of 8th Member of Lower Shihezi Formation in Sulige Gas-Field

The sand of 8th Member of Lower Shihezi Formation in Sulige Gas-field is thick and has complex structure. The reservoir lateral changes quickly and effectively lower reservoir drilling. Through outcrop, modern river sediments and core observation, the composite river fancies types, sedimentary characteristics,the reservoir internal structure, spatial overlay mode and developmental scale of the 8th Member of Lower Shihezi Formation are studied to deepen the understanding of the reservoir, deployment and guidance of exploration.
