电成像测井在砂砾岩体沉积特征研究中的应用
Application of electrical image logging in the study of sedimentary characteristics of sandy conglomerates
摘要
Abstract
The northern steep-slope region in the Dongying Sag developed sandy conglomerate reservoirs of various origins. However, it is difficult to identify lithology and sedimentary microfacies using conventional logs owing to complex provenance and sedimentary process. The selected research object is the upper Es4 sandy conglomerate reservoir of the Yanjia Oilfield. By use of core and formation micro-resistivity imager (FMI) data, the FMI image features of lithology, sedimentary structure and rhythm of different sandy conglomerates are analyzed, and an image model of geologic significance is established. Then in combination with conventional logging, borehole log, and physical properties data, the sedimentary cycle and sedimentary facies of single well sandy conglomerate bodies are divided, and the plane distribution of sedimentary fades of sandy conglomerate bodies is concluded, which provides a basis for mapping sedimentary facics and searching for favorable hydrocarbon zones in the study area.关键词
