测井约束反演技术在滨里海盆地A油田储层预测中的应用
|
摘要
地震反演技术是储层预测的核心技术,测井约束反演是开展储层预测常用的反演技术之一。本文介绍了测井约束反演的技术原理,以滨里海盆地A油田为例,首先从岩性、测井响应和地震剖面特征三方面,对工区内储层的基本特征进行了描述。然后分析了测井约束反演中测井曲线的标准化、合成记录与标定、子波提取和建立地质模型等一些关键技术环节,结合得到的反演结果,对有利储层砂体的展布、厚度等进行初步分析,发现砂体发育的总体趋势为西南侧厚,东北侧薄。最后认为工区的西南部埋藏较深处为有利的目标区域,为该区今后的井位部署提供了重要的依据。
Seismic inversion is the core technology of reservoir prediction,and logging constrained inversion is one of the most prevalent inversion technology to carry out reservoir prediction.This paper introduces the technical principles of logging constrained inversion.Taking A Filed of Pre-Caspian Basin as an example,first of all,the author described the basic characteristics of the reservoir in the region.Secondly,some key techniques of logging constrained inversion were analyzed,and the appropriate parameters were selected.Combined with the inversion results,the distribution and thickness of favorable reservoir sand body were analyzed.Finally,a favorable target area which was pointed out.The above results provide an important reference for geometric arrangement of wells in the future.
