A quantitative research method on the sealing of growth faults: A case study of JX1-1 oil field in Liaozhong Sag, Liaohe Depression

School of Geosciences, China University of Petroleum, Qingdao, Shandong 266580, China

摘要

摘要: 通过对生长断层封闭性的封闭机理和影响因素分析和研究，以断层体为研究对象，提出了断层封闭综合指数（F_ci）的概念，用断面正压力、断层带泥质含量，断层带碎屑物成岩胶结作用三大影响因素量化乘积表示。以辽中凹陷JX1-1油田作为研究实例，建立了该区断层的封闭性评价标准，断层封闭综合指数60作为临界值，高于该值断层具有较好的封闭性，低于该值断层难以封闭住油气，并分析了经过该区的主要断层——辽中一号主干断裂的控藏作用。

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 (F_ci) 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 accumulation of the main fault in the study area, Liaozhong no.1 fault, were analyzed.
