| 摘 要： | 关键词：火烧山油藏是准噶尔盆地东部复杂的裂缝性油藏，裂缝分布规律和渗流机理复杂。油藏开发初期效果较差，受裂缝影响，注入水运动规律极难把握，给剩余油的认识带来较大困难。在分析该油藏裂缝发育特征和分布规律的基础上，结合裂缝的发育方向类型以及该区的成藏模式，得到了裂缝的分布规律；根据裂缝与砂岩基质的四种组合的水驱油模式，以及该区油井的含水上升规律，利用油藏数值模拟技术得出了油藏的剩余油分布规律。研究认为，火烧山油藏中裂缝的主要影响因素是构造作用和岩性变化，其分布为大裂缝发育区、微细裂缝发育区和裂缝弱发育区；由于水窜的影响，大裂缝发育区内的基质还存留大量的剩余油；弱裂缝发育区中吸水能力差，水驱油效果差，也存留大量的剩余油。最后通过建立地质模型、运用油藏工程分析方法和数值模拟手段，得到了H3油藏的剩余油分布现状，为后续的调整措施提供了依据。

| Abstract: | Located in the eastern Junggar Basin,the Huoshaoshan oil reservoir is characterized by complex fracture distribution and percolation mechanism.Due to the complexity of fractures,the effect of development was poor at the very beginning,the flow pattern of injected water is hard to understand,and the remaining oil distribution is difficult to predict.Based on analysis of the characters and orientation of the fractures and the reservoir-forming patterns,we understood the distribution of the fractures in the re... |
