双侧向测井裂缝孔隙模型考察与改进
EXAMINATION AND IMPROVEMENT OF FRACTURE-PORE MODEL FOR DUAL-LATERAL LOGGING
摘要
Abstract
Fracture pore evaluation belongs to the study of fractured hydrocarbon reservoir. Because the fracture pore model based on dual-lateral logging aims at carbonate formation and is inadaptable to sandstone formation. Relatively high permeability and porosity of matrix and mud invasion into matrix pore have great influence on dual-lateral difference. Considering this, travel path of dual-lateral logging electricity in fractured sandstone reservoir is analyzed, and an improved dual-porous fracture pore evaluation model is proposed initialing from matrix pore and fracture pore parallel conductance model. Examination on the application effect of fracture pore model shows that the improved model increases the calculation precision of fracture pore and provides new method and ideas for fracture pore evaluation.关键词
