苏14井区位于位于苏里格气田中区南部,选取下石盒子组盒8段为研究对象,将油气勘探和开发作为目标,运用沉积学、石油地质学等理论为指导,利用测井、岩心观察、野外露头剖面等多种方法,对研究区目的层段沉积相进行研究。结果表明:盒8下段发育辫状河沉积并且河道亚相十分发育,盒8上段发育曲流河沉积。其中盒8下砂体最发育,为工区的主力产气层。 Well Su 14 is located in the southern part of the middle area of ​​Sulige gas field. The 8th member of Xiashihezi Formation is selected as the research object. With the goal of oil and gas exploration and development as the guideline, using the theories of sedimentology and petroleum geology, Core observation, outcrop profile and many other methods to study the sedimentary facies of the study area. The results show that the braided river sediments developed in the lower part of the box 8 and the channel subfacies developed very well, and meandering river deposits developed in the upper part of the box 8. Among them, box 8 is the most developed sand body, which is the main gas production zone in the work area.
