摘要：
According to the characteristic of ground stress field of Luodai Penglaizhen Formation gas field, this artical analyzes the attitude, length and width of the artificially cracking fracture on the basis of unstable well test. The results show that the state of ground stress is σx>σz>σy and the fractures induced by the artificially fracturing crack is vertical with the length ranging from 30 m to 220 m ,the width from 3 mm to 10 mm and the height about 20 m.
