阵列感应测井技术的产生, 较好的解决了常规感应测井仪器中存在的纵向分辨率差、径向探测深度不固定、不能解决复杂侵入剖面等问题。文章以阿特拉斯公司的阵列感应测井仪器HDIL为例, 着重介绍它在辽河油田海上勘探中的应用, 消除由于使用矿化度较高的咸水泥浆和侵入较深造成电阻率数值较低的影响, 从阵列感应测井曲线的形态、数值及其径向关系等几个方面总结分析了其在测井油气水层评价中的作用, 建立了阵列感应测井资料在储层评价中的分析模式, 奠定了常规测井资料不可替代的重要地位。

The array induction logging technique provides better solutions than the traditional induction tools for those problems, such as bad vertical definition, instable radical depth of investigation and sophisticated invaded profile. In this paper, the author primarily introduces its application to the offshore exploration in Liaohe oilfield.We can eliminate the bad effect of low resistivity value derived from the mud of high salinity and deep filtrate invasion. The author also summarizes and analyzes its importance on the evaluation of hydrocarbon reservoirs after studied the features, values and radial relations of the Array Induction curves. In addition, the author finds an analysis model of reservoir evaluation by using Array Induction data and pointes out the unique status of conventional log.
