摘　　要：为了系统评价加拿大西加盆地K地区海相页岩气都沃内地层的资源潜力,从烃源岩品质、储层品质及完井品质等方面入手,形成了一套页岩气测井综合评价技术。对地化参数指标、矿物组分分析以及可压裂性评价等3个环节进行阐述,使用岩心分析及微地震监测结果进行了验证。对单井油气资源量进行了精细评价,同美国五大已开发盆地地质评价参数进行对比,探讨了测井资料在压裂高度预测中的可行性。该评价技术在该地区适用性良好,为地区页岩气的勘探开发提供了研究手段,也为国内外页岩气区块综合研究提供借鉴。In order to systematically evaluate the resource potential of the Duvernay reservoir-marine shale gasin area K of the western Canada basin,researchers started with source rock quality,reservoir quality and completion quality,formed a set of comprehensive evaluation technology for shale gas logging.This paper expounds the three characteristic parts of geochemical parameters,mineral composition analysis,and fracturability evaluation,all of which were verified with core analysis and microseismic results.The oil and gas resources of wells were evaluated in detail and compared with the geological evaluation parameters of the five major developed basins in the United States.The feasibility of logging data in fracturing barrier tops prediction is discussed.This evaluation technology has good applicability in this area,and provides research methods for the shale gas exploration and development in this area,as well as a reference for the comprehensive study of other shale gas play.
