摘要: 针对惠民凹陷岩性油藏勘探存在的难题,开展了岩性油藏勘探技术研究。以地震、地质资料为基础,采用井震联合及小波变换技术,完善了层序地层等时格架建立方法,确定了各三角洲的时空展布规律。应用多元综合标定、地震相划分、正演模拟和测井约束反演一系列技术,实现了不同沉积类型有利砂体的描述。形成了适合惠民凹陷沙三段岩性油藏勘探的技术系列,可以指导惠民凹陷沙三段岩性油藏的勘探。

Abstract: Based on the problem of oil prospecting in Huimin Depression, the prospecting technology for lithological oil reservoir is studied.Combined logging and seismic as well as wavelet transform technology, the method to establish isochronic framwork of stratigraphic sequence is presented, and the space-time distribution in each belta is determined.Using multivariate composite calibration, classification of seismic facies, forward modeling and logging constrained inversion technique, we realized the description of beneficial sand body in dissimilarity sedimentation type, and formed a technical series that fit for the prospeting in Huimin area.
