Abstract

H gas reservoir is an overpressured gas reservoir with high temperature. It is generally believed that overpressured gas reservoir exist stress sensitivity effect due to uncompaction. Firstly, this study conducted lab core test to analysis stress sensitivity of rock by defined confining pressure and decreasing inner pressure. Test results show that the reservoir processes weak to medium stress sensibility. Then, according to mineral composition analysis and strain-stress curve comparison of the cores, stress sensibility is considered to be mainly caused by low hardness clay mineral. Finally, based on well testing data of well H-X-1, we used pseudo-pressure binomial deliverability equation considering stress sensitivity to discuss the influences of stress sensibility on productivity. Results show that the stronger the stress sensibility is, the more obviously productivity decreases. As stress sensibility of the block is weak to medium, it has little impact on productivity.
