鄂尔多斯盆地LFP区块长2段沉积相研究
|
摘要
储层的沉积相研究通常是油气藏勘探开发过程中一项十分重要的任务,它控制着储集砂体的成因类型及宏观分布。在岩芯观察的基础上,结合综合录井资料和野外露头剖面信息,运用沉积学、沉积构造、剖面结构、古生物及测井相等划分沉积相的标志,对研究区内钻井进行单井沉积相划分,对不同钻井之间的沉积相进行综合比对,结果认为LEP区块长2段主要从三角洲前缘高建设的水下分流河道骨架砂体沉积为主。
Reservoir sedimentary facies study is usually an important reservoir exploration and development task,it controls the genetic types and macro distribution of reservoir sand bodies. On the basis of core observation,according to the outcrop section information and comprehensive logging data,we use of sedimentology,paleontology,sedimentary structure,profile structure and logging equal dividing sedimentary facies marks,drilling in the area of study on single well sedimentary facies classification,on this basis to make a comprehensive comparison of sedimentary facies,between different drilling and exposes in the LFP blocks long 2 characteristics of sedimentary facies and sedimentary environment changes.
