    Abstract
  • The gas pool in the Lower Shaximiao Formation of Xinchang gasfield is another gas-bearing interval discovered recently in the distal gas reservoirs of tight clastic rock in West Sichuan province.By study on the geophysical properties of gas-bearing sandbodies and the basic geological characteristics of the gas pool in this paper,it is summarized that the control factors of natural gas enrichment for this gas pool are mainly reservoir sedimentary microfacies and gas-bearing sand bodies show the negative reflection seismic response features of medium-strong amplitude and low impedance.Based on the acknowledge of gas pool characteristics,the gas pool is predicted and evaluated combined with favorable reservoir microfacies distribution,seismic response and other characteristics.
