东河塘1油田块状巨厚CⅢ砂岩油藏断层封堵性研究

Research on Fault Sealing Capacity in the Donghetang 1 Carboniferous Thick Block Sand Rock Oilfield

东河塘1油田CⅢ砂岩油藏区域内断层相当发育,断层的封堵性判定对油田开发方案的制定至关重要。在此以东河塘1油田CⅢ油藏3号断层为例,运用泥岩断层泥比法(SGR)作为评价参数,将生产动态井间干扰和示踪剂监测作为论证方法,定量分析其封堵性。对开展区域断层的封堵性研究和分区注水开发具有借鉴作用。

With rather well-developed faults in the Donghetang1 carboniferous sand rock oilfield, judgment of fault sealing is very important for oilfield development program. Taking Donghetang1 carboniferous sand rock oilfield as an example, it uses shale gouge ratio （SGR） as the evaluation parameter, inter-well interference and tracer monitoring as proof methods, to research its sealing with quantitative analysis, which is helpful to the research of fault sealing and divisional waterflooding development.
