Research and Application of Ways to Identify Efficient Wells for Tight Sandstone Gas Reservoir of Narrow Channel:A case study of narrow channel tight sandstone gas reservoirs in Western Sichuan as an example
Explore new technological methods for identifying efficient wells for benefit development for tight sandstone gas reservoir of narrow channel. Based on investigation and the practice of gas field,build the production prediction model of gas wells for tight sandstone gas reservoir of narrow channel, and combine it with the theory of economic evaluation of gas reservoir development to set up the ways of identifying efficient wells with the factor of internal rate of return. Examples show it is reliable to pick up efficient wells, which makes up the absolute open flow capacity of a gas well as the productivity evaluation criteria at present. So it is of importance for the identification of efficient wells, and it helps to make clear production characteristics of efficient wells, deploy gas wells and optimize development scheme of gas field. And it is a new way for improving profits for companies.
