摘要
Abstract
Through the analyses of the mechanism and influencing factors of the sealing of growth faults, taking the fault body as the research object,the concept of fault closure composite index(Fci)was put forward,which was the quantified product of three factors including the fault positive pressure,the muddy content of fault zone, and the cementation of debris in fault zone. Taking the JX1-1 oil field in the Liaozhong Sag as an example, a fault sealing evaluation standard was established. The fault closure composite index of 60 is regarded as a critical value. Faults can seal oil and gas well when the index is over 60. The controlling effects on hydrocarbon accumu-lation of the main fault in the study area,Liaozhong no.1 fault,were analyzed.关键词
