In the early Paleozoic and Indosinian cycle, the tectonic movement is weak, and the rock has acoustic emission once, whose maximum paleo-stress is 13.3MPa and 24MPa, moreover the Majiang ancient reservoir is in the mainly accumulation period; the high frequency and intensity paleo-stress correspond to the Majiang ancient reservoir's reservoir comes into being or destruction. The single Neopaleozoic acoustic emission whose maximum paleo-stress is 92.6MPa means the reservoir comes into being.
