摘要: 裂缝的有效性主要取决于裂缝的张开程度和径向延伸情况,微电阻率成像测井能有效识别裂缝,但它不能对裂缝的径向延伸情况做出判断,采用微电阻率成像测井与方位电阻率相结合的方法可确定裂缝的有效性。对于没有测新技术的井,利用双侧向的差异特征也能确定裂缝的有效性。对于碳酸盐岩中复杂孔隙结构储层、层状地层、孤立孔洞性地层,仅靠常规测井曲线响应特征常常会得出错误的解释结论,必须立足于储层地质特征才能对储层有效性做出可
靠的评价。

Abstract: The effectiveness of fracture largely depends on fracture apertures and radial extension. Formation microresistivity image logging can effectively identify the fracture, but it can not judge radial extension. Using formation micro-resistivity imaging logging with ARI logging can determine the effectiveness of fracture. In the absence of advanced logging technology, the use of differences of dual lateral logging can also be used to determine the effectiveness of fractures. For the carbonate rock reservoir with the complex pore structure, layered strata, isolated cavity strata, conventional logs response characteristics alone will often lead to the wrong interpretation. Conclusions must be based on reservoir geological characteristics to make an reasonable assessment of reservoir effectiveness.

Key words: reservoir effectiveness, image logging, dual lateral logging, pore structure, layered strata, isolated cavity
