摘要： 断层封闭性具有侧向封闭性和垂向封闭性两方面的含义。断层封闭与否,不是简单地取决于断层两盘的岩性,断裂带性质是关键因素,据此提出了一种具有普遍适用性和实用性的断层封闭性综合分析方法,即通过研究断层两侧储集层的油水界面、过断层井的声波时差测井资料和统计分析断裂带的泥岩涂抹系数,综合判断断层的封闭状况。并用实例说明本方法对于确定断层侧向封闭性和垂向封闭性具有良好的效果。

关键词: 断层, 断裂带, 声波测井, 泥岩涂抹系数, 封闭性

Abstract: It is significant effect of studying the fault sealing properties, (i.e. lateral sealing factors such as filling compounds, allocated lithol-ogy of fault walls and syngenetic fault feature; and vertical sealing factors including the fault mechanics, geometry, stress field, faulted overly-ing strata) on determination of the distribution of reservoirs in complex fault block. The block sealing is not simply dependent on the lithology of fault walls, but on the property of fault zones. This paper presents an integrated approach of block sealing analysis with applicability and practicability. From the studies of oil-water contact in reservoir on two sides of the fault, acoustic logging data from over-fault wells and shale smear factor (Fss), the sealing status of fault is comprehensively estimated. A case is used to demonstrate the good effectiveness for ascertain-ing the lateral and vertical sealing properties of the faults by applying this approach.

Key words: fault, fault block, acoustic logging, Fss, fault sealing property
