近日,国内首口应用多硅基强封堵水基钻井液技术钻探的页岩油气藏水平井——东平1井顺利完井。该钻井液体系在该井的成功应用,解决了页岩井壁稳定技术难题,大大降低了钻井成本。东平1井由胜利黄河钻井公司50570队承钻,胜利钻井院提供三开钻井液技术支撑。该井钻探主要目的是探索评价麻黄山西区块泥页岩特征及含油(气)性,同时利用水平井方式,评价长7油层组泥页岩含油(气)
Recently, the first domestic well for drilling shale reservoirs, the Dongping-1 horizontal well, to be drilled with a silicon-based strong sealing water-based drilling fluid technology was successfully completed. The drilling fluid system is successfully applied in the well, which solves the technical problem of shaft wall stability and greatly reduces the drilling cost. Dongping-1 Well Drilling by the Yellow River drilling company 50570 team drilled, Shengli Drilling Institute to provide three open drilling fluid technical support. The main purpose of this well drilling is to explore and evaluate the shale characteristics and oil (gas) properties in the western section of the Mahuang area. Meanwhile, the horizontal well method is used to evaluate the oil and gas content of the shale in the Chang7 oil-
