Characteristic and Development Techniques of Sulige Tight Gas Pool

Ordos basin with abundance of tight gas is a backup area of natural gas exploration.Based on reviewing tight gas development and present situation,we discuss the characteristics of Sulige tight gas reservoirs as a typical case and compare the features of geological background and gas reservoir between American developed tight gas field and Sulige gasfield.Four types are classified.Based on development history and test results,we conclude development difficulties and challenges of tight gas reservoir,and point out the the following research direction in the future.
