随着油气资源的日趋紧缺和对于能源安全的考虑,非常规页岩油气储层已成为世界能源研究的热点之一。目前,北美地区页岩气实现商业性开发,2011年,美国页岩气产量突破1800亿方,主要形成了页岩气缝网体积压裂形成的判断条件、降阻水大型加砂分段压裂工艺技术、裂缝实时监测技术,实现了该类型油气储层的有效动用。由于国内外页岩油气储层的沉积类型、矿物成分及流体特征(胜利以页岩油为主)存在巨大差异,因此本文主要针对胜利油田陆相页岩油气储层特征、储层可压性、裂缝起裂和裂缝延伸规律进行了基础性研究,对压裂工艺技术进行攻关研究,完成了渤页平1井第1段、第2段的压裂施工,初步提出了页岩油气储层的压裂改造思路。
With the increasing shortage of oil and gas resources and the consideration of energy security, unconventional shale oil and gas reservoirs have become one of the hot topics in the world energy research. Currently, shale gas in North America is commercially exploited. In 2011, shale gas production in the United States exceeded 180 billion cubic meters, mainly forming the judgment condition for the volume fracturing of shale gas seam network. Crack technology, crack real-time monitoring technology to achieve the effective use of this type of oil and gas reservoirs. Due to the huge differences in sedimentary types, mineral compositions and fluid characteristics of shale oil and gas reservoirs at home and abroad (mainly shale oil), this paper mainly focuses on the characteristics of oil and gas reservoirs in the continental shales of Shengli Oilfield, , Crack initiation and crack extension, and studied the fracturing technology to complete the fracturing construction in the first and the second sections of Bojiao 1 well, initially proposed the shale oil and gas reservoir Fracturing transformation ideas.
