摘要
针对油基钻井液环保压力大、配制成本高等瓶颈问题,开展了环保型、低成本、高性能的聚醚胺基烷基糖苷(NAPG)类油基钻井液研究。以NAPG作为核心主剂,优选增粘剂、降滤失剂、封堵剂等配伍处理剂,通过钻井液体系构建及配方优化,形成了环保型、低成本、高性能的NAPG类油基钻井液体系。对钻井液性能进行了评价,结果表明:钻井液页岩一次回收率为99.90%,相对回收率为99.98%;钻井液抗温达150℃,流变性好,动塑比0.327,初终切适宜,中压滤失量0mL、高温高压滤失量6.0mL;润滑系数降低率达69.62%;滤液表面张力26.60 mN/m;钻井液抗盐达饱和,抗钙10%,抗土、钻屑20%,抗水40%,抗原油20%;岩心动静态渗透率恢复值为91.4%和96.8%;钻井液EC_(50)值为528800 mg/L,无生物毒性。对NAPG类油基钻井液和油基钻井液从抑制、润滑、降滤失、储层保护及生物毒性等方面进行了对比,结果表明,两者性能相当,且类油基钻井液在环保方面具有显著优势。NAPG类油基钻井液适用于强水敏性泥岩、含泥岩等易坍塌地层及页岩气水平井钻井施工,可缓解目前油基钻井液环保压力,扩大水基钻井液适用范围,具有较好的推广应用前景。
In view of the problems of environmental protection pressure and high preparation cost for the oil based drilling fluid,the research of NAPG similar oil based drilling fluids with the advantages of green,low cost and high performance was carried out.Taking the NAPG produc as the main treating agent,the compatibility treatment agents including tackifier,filtration reducing agent and plugging agent were selected out,through the construction of drilling fluid system and formulation optimization,NAPG similar oil based drilling fluids with the advantages of green,low cost and high performance was formed.NAPG similar oil based drilling fluid is suitable for the high water sensitive mudstone,shale and other easy to collapse formation and shale gas horizontal well drilling construction,which can ease the current environmental protection pressure of oil based drilling fluid,expand the application scope of of water-based drilling fluid,and has a good prospect of popularization and application.
