Abstract

Abstract:

Carbonate form ation is characterized by strong reservoir heterogeneity. As well as lack of sufficient knowledge and information about reservoir, it is difficult to judge the connectivity between wells. The reservoir connectivity is analyzed by the method of water injection effectiveness in S48 well block. The research result shows that this method can reflect the connectivity of fracture-cavity block between the producing wells.

Key words: Yanchang Form ation, anomalous overpressure, episodic accumulation, thickness of hydrocarbon expulsion, Ordos Basin
