【摘要】 针对沙7断块开发中后期暴露出的含水上升快、递减快、压力水平低、注入水外溢量大、水淹严重等诸多矛盾,为保证该块继续稳产,充分利用该区地震、钻井、取心、测井、测试以及生产等资料,按照数字化精细油藏描述的要求,采用小层精细对比技术、微构造研究技术、沉积微相分析技术、动静结合描述储层非均质技术和微观储层评价技术(恒速压汞和核磁共振技术)以及精细三维地质建模技术,对研究区开发地质做了深入、系统的研究,研究结果可为该块下一步综合开发调整提供较为可靠的地质依据。更多还原

【Abstract】 Many of the problems exposed in Fault Block Sha 7 at the late stage of development,such as water-cut rising fast,fast production decline,low pressure,serious injected water overflow and serious water out.To ensure the continuous and stable block,seismic,drilling,coring,logging,and production test data are fully used and according to the requirements of digital and fine reservoir description,techniques of fine contrast of small layers,micro structural study,sedimentary micro-facies analysis and in combination with the reservoir heterogeneity description,microscopic reservoir evaluation(rate-controlled mercury and NMR techniques) and the fine 3D geological modeling are all used for deeply and systematically studying the development geology in the studied area,it provides reliable geologic basis for next integrated development and adjustment of the block.更多还原
