摘要

In order to study gas transporting capacity of Chengzihe Formation in Suibin Depression, on the basis of research of faults and sandbody development and distribution, the authors have made an evaluation of gas of transporting capacity in Chengzihe Formation by defining and calculating the evaluation parameters of the faults and sandbodies, and arrived at the conclusion that the area of high gas transporting capacity of Chengzihe Formation mainly distributes in the north pitch area in SuiD2 well and the pitch area of eastern part of Jixian Town, the gas transporting capacity of fault in east part is higher than that in the west part. According to the evaluation result of gas transporting capacity of fault and sandbody, combining the development characteristic of source rock and trap, the authors carried on the forecast to the advantageous area of gas reservoir in Chengzihe Formation of Suibin Depression, and reached the conclusion that the center part of Fuxing pitch area and the south part of eastern pitch area are the advantageous area of gas reservoir and distribution in Chengzihe Formation of Suibin depression, which are advantageous area for the next step of gas exploration in this area.
