【摘要】 继"页岩气风暴"后,在石油价格在不断走高,而天然气价格处于较低价位的背景之下,北美又掀起了致密油勘探开发新热潮。中国致密油具有较好的发展前景,借鉴北美致密油商业化勘探开发的有效实践,可为中国实现石油安全供给提供保障。本文采用了文献综述法、对比分析法、案例剖析法等,在致密油基本特征的分析之上,追踪北美致密油勘探开发的实践,针对中国致密油资源潜力及勘探现状,探讨美国致密油开发实践模式给中国的启示:上下钻探双重水平井、应用三维地震资料确定钻探井、尝试使用丙烷或液化丙烷气(LPG)作为压裂支撑剂的运载液体、探索采用较低的泵率及增加单井压裂级数,在压裂过程及返排中必须确保钻井表层套管水泥封堵良好,在同一井场钻探多口井乃至数十口井等,以试图解决困扰中国致密油开采的成本高企、开采风险、水资源缺乏、环境污染等问题。更多还原

【Abstract】 After "shale gas storm" throughout the world,under the background that oil prices continue to rise,while natural gas prices at a lower price,the exploration & development of tight oil has raised a new upsurge in North America.China has abundant tight oil resource potential and promising prospect of development,which will guarantee the national energy security based on the successful commercial pratice of tight oil exploration & development from USA.In this paper,a literature review,comparative analysis,case analysis method,etc.,on top of the basic characteristics of tight oil analysis,tracking practice of tight oil exploration and developmentin North America.According to the the status quo of tight oil resources exploration potential in China,we discussed American tight oil development practice mode inspiration to China:Drilling down double horizontal wells,applying three-dimensional seismic data to determine the drilled well,try to use propane or liquefied propane gas(LPG) as a carrier liquid fracturing proppant,explore a lower rate and increase the single well fracturing pump series In the fracturing process and drilling flowback,we must ensure good surface casing cement block at the same wellsite drilling multiple wells,even dozens of wells in an attempt to solve the problems of tight oil exploration in China,such as high cost of oil exploitation,mining risks,water lack of resources,environmental pollution and other issues.更多还原
