Reasonably Water Injection Time about Abnormal Pressure of Low Permeability Reservoir

Abstract:

Abnormal pressure of low permeability reservoirs is a special reservoir, which have some characteristic : low permeability, strong stress sensitivity, complex pore structure, abnormal pressure. with the pressure decreasing about bottom-hole and reservoir, the formation of the rock pore space and permeability will decrease, and reservoir stress-sensitive phenomenon of serious. All these have brought greater difficulty for developing. in order to reasonable development of those reservoirs, maintain the formation energy is important, choose the reasonable injection timing is an important aspect. In this paper, taking abnormal pressure of low permeability reservoir as an example, studies variation law of abnormally pressure reservoir rock compressibility, porosity, stress sensitivity by experimental, Associated with the nature of the reservoir to determine a reasonable water injection time, and demonstrated by numerical simulation, finally proposed reasonable water injection timing about abnormal pressure of low-permeability reservoirs.
