Fracture/Cave Distribution and Oil & Gas Accumulation in Block 4, Tahe Oilfield

Abstract

Abstract: For revealing the distribution of fractures and caves and then analyzing the effect of fracture and caves on oil and gas distribution, a comprehensive technology and method like geology, geophysics, logging and drilling are used to analyze the control of faults to fractures and the correlation of faults, fractures, and karsts. The results show that the karst development is controlled by the fault system which also promotes karst development. Fractures and karst supplement and complement each other. Fault zone is the favorable area for fracture and karst development and oil/gas distribution

Key words: carbonate, fracture, karst, distribution
