| 摘 要： | 页岩气井位优选在于选准最佳的勘探层段、缩小目标范围,部署最有利页岩气区域,减少钻探风险,减低勘查成本,加速成果突破的目的。本文在中牟区块现有油气地质资料、钻井样品测试地化成果、三维地震勘探成果的基础上,综合研究后确定太原组-山西组泥页岩在2806m—2979m段为页岩气勘探井位最有利层位;依据沉积、构造、TOC、有机质成熟度、含气量、脆性、裂缝、可压性等成果数据要素,通过软件优选多要素叠加成图,圈定各项特征相对好的区域作为页岩气勘探目标区,圈定区块内四个页岩气勘探范围。已在优选范围部署一口探井现已排采试气,得了较好的页岩气显示。

| Abstract: | The optimization of exploration well for shale gas is aimed at finding exactly the best exploration stratum, narrowing the target range, locating the best favorable shale gas area, reducing the exploration risk and prospecting cost, accelerating the breakthrough. Based on the avillable geological data, geochemical analysis of samples from bore holes and 3D seismmic survey operated in Zhongmu Block integrated study is carried out to determine the 2 806 m to 2 979 m interval of mudy shale of Taiyuan-Shanxi Formation as the most favorable shale gas exploration horizon. According to the result and data of deposition, structure, TOC, organics maturity, gas content, fragility, fissure and compressibility the software-optimized factor overlay map is drwn. From the map areas with all relatively better characteristics are chosen to be the targets and from the targets 4 exploration blocks are located and 1 exploration well is deployied with preferable shale gas shows. |
