油田进入开发中后期后,储层研究工作尤为重要。沉积相控制储层的空间展布和储层的物性特征,充分利用测井资料研究沉积相是储层研究的重要手段。本文提出了测井储层沉积相分析方法:在地质分层的基础上,分析测井曲线特征,提取储层参数,进行单井沉积相划分,最后根据沉积学理论和油田具体地质背景编制沉积相带平面图。利用此方法对辽河油田更黄66井区进行了测井储层沉积相分析工作,作为最终成果的沉积相带平面图能够指导油田部署开发井。
After the oilfield enters the late stage of development, reservoir research is especially important. Sedimentary facies control the spatial distribution of reservoir and reservoir physical characteristics, and make full use of logging data to study sedimentary facies is an important means of reservoir research. In this paper, the method of sedimentary facies analysis of logging reservoir is proposed. Based on the geological stratification, the logging curve characteristics are analyzed, the reservoir parameters are extracted and the sedimentary facies of single well are divided. Finally, sedimentology is compiled according to sedimentology theory and oilfield specific geological background Phase belt plan. This method is used to analyze the sedimentary facies of logging reservoirs in the area of Huang-66 in Liaohe Oilfield. The sedimentary facies plan as the final result can guide the development of oilfield development wells.
