Xing Northeastern Sichuan Basin - Feixianguan is found in China in recent years, an important gas reservoir, has become the focus of China's oil and gas exploration areas. Through the northeastern Sichuan Changxing - Feixianguan sedimentary facies analysis, reservoir development to explore its mechanism. The study found that in the northeastern Sichuan Changxing - Feixianguan mainly developed with shelf, slope, open platform, restricted platform and platform margin depositional units such reef, platform margin reef area with the most favorable reservoir facies, reef, shoal development on a variety of rock particles, soil particles or rock oolite, buried by selective dolomitization and dissolution to form a variety of secondary holes, holes, seam seepage reservoir body, they are surrounded by dense rock body surrounded by block and overlying argillaceous, cream quality rock blocks formed traps.
