【摘要】 页岩油气是具有商业价值的非常规能源资源,美国对页岩油气的成功开采使得世界各国对其开发和利用越来越重视。页岩气的储藏特性及地质环境决定了只有采取储层改造措施才能实现增产。选取美国巴奈特、鹰滩2个页岩油气田实例,通过储层评价及地层化学分析,认识到天然裂缝、泥质含量等参数在井位选取、完井方案的优化方面的作用,同时应用水平井钻井导向技术、压裂完井技术,可以有效实现非常规油气田的增产。更多还原

【Abstract】 Shale oil and gas is unconventional energy resources with commercial value,the success of US exploitation of it makes the world pay more and more attention to their development and use. The shale oil and gas reservoir characteristics and geological environment determine that only stimulating reservoirs can increase production. two cases at Barnet,Eagle beach in the United States are selected,and through reservoir evaluation and chemostraigraphy analysis,it is recognized that parameters of natural fractures,clay content etc are important in the well site selection,well completion optimization,as well as application of oriented drilling technology of horizontal well,fracturing and completion technology,can effectively increase unconventional oil and gas production.更多还原
