Abnormal high pressure reservoir is one with a pressure coefficient over 1.2. The possibility of formation fracturing by the pore pressure of itself is discussed. The result shows that due to the pressure pressing between pores, pore pressure can never fracture the formation itself. The fractures in formations, if possible, are all resulted from the change of external pressure acting on the formations. The rock of highly abnormal pressure reservoir is quite tight, so the rock compressibility is not very high as researchers think usually, but takes quite lowvalue.
