摘要:
柴達木盆地英西深層湖相碳酸鹽巖油藏近年來勘探獲得了突破,測井解釋面臨儲層識別與油水區分的巨大挑戰。目的層普遍采集了常規、高分辨率電成像及巖性掃描等測井系列。礦物成分以巖性掃描測井的元素含量為基礎,通過最優化方法進行計算。孔隙度以礦物成分為基礎,結合密度曲線采用變骨架值的方法獲得。高分辨率電成像劃分地層結構,精細描述裂縫與溶蝕孔洞。熱中子俘獲截面法區分油水,雙重介質模型計算含油飽和度,部分井采用介電掃描測井進行流體識別。多井測試證明,該方法較好地解決了英西復雜湖相碳酸鹽巖儲層的測井評價難題。
Abstract:
A big breakthrough has been made in exploring the lacustrine carbonate reservoir in the Yingxi block in the Qaidam Basin, but reservoir identification and determination between oil layers and water layers are two major challenges in log interpretation. Target layers are usually interpreted by conventional log data, FMI data and lithologic scanning data. This paper estimates the mineral content using ELAN based on the elements from lithologic scanning logging data, calculates the porosity by integrating minerals with density curves of variable bulk values, divides the stratigraphic structure and finely describes the fractures and dissolved holes using high-resolution electrical imaging data, distinguishes oil from water using thermal neutron capture crosssections, calculates the water saturation by a dual-pore model, and in some wells, uses dielectric logging data to identify fluid. Logging results from many wells show that these methods can successfully solve the problems in log interpretation for the lacustrine carbonate reservoir in the Yingxi block.
