摘要
Abstract
The lithology evaluation of reservoir is the basis for oil and gas exploration in metamorphic rock.Based on the core observation of the typical wells in the metamorphic rock reservoirs of the XX oilfield and the geological understanding, this paper makes full use of core, conventional logging and high-resolution imaging logging to systematically summarize the log response characteristics of lithology in metamorphic rock and the identification methods for effective reservoir.A total of four types of lithologic log response characteristics are summarized.Its main principle is to use the porosity logging program and imaging logging to effectively identify lithology of metamorphic rock, based on the imaging logging, a logging multi-plate identification method for metamorphic rocks is established.In addition, the problem of fracture identification and effectiveness evaluation of metamorphic rock reservoirs are solved by imaging logging and nuclear magnetic resonance logging, and the dominant facies of metamorphic rocks in this area is determined.This method has been applied to the multiple wells and obtain great result on lithology identification and effectiveness evaluation of reservoir.关键词
