摘　　要：层间圈闭的解释方法，首先对测井曲线分段求出变V0和变β速度参数，使深度－时间转换准确；然后用约束反演方法合成井旁地震道，以此细致地标定地震反射层位；最后用储层横向预测方法对层间圈闭进行定量研究，编制层间圈闭顶面构造图及储层厚度图。该方法应用于泌阳凹陷B93井区，新发现3个层间圈闭，总面积5．03km2，为该区的油气勘探提供了新的目标。Interpretation methods of interlayer traps are introduced in this paper. Firstly, segment logging curves and abtain velocities with variable - Voand variable - β to ensure that depth time conversion is accurate;secondly synthesize near- wellbore seismic traces through constrained inversion to nnely calibrate seismic renection horizonsi finally,quantitatively study interlayer traps with lateral reservoir prediction methods and map interlayer trap top structures and reseroir thickness. These methods were applied in Wellblock B93 in Biyang sag, 3 interlayer traps with a total area of 5.03 km2 were discovcred.They are new targets for petroleum exploration in this area.
