摘 要 关键词：；； Abstract . This paper expounds the distribution characteristic of heavy oil resources at home and abroad, as well as the recovery situation, summarizes the transverse comparison of domestic and foreign various oilfield, summarizes the development situation of heavy oil exploitation at home and abroad and the development of the meaning of the thick oil mining technology. Detailed introduces the various mining methods and their advantages and disadvantages of heavy oil, and introduces the thick oil mining technical basic equipment you need. In addition, this article has a structure of thermal recovery of heavy oil underground heat insulation pipe string of results, and theoretically analyzes the mechanism of heat insulation oil pipe insulation. Finally the various technique in layered oil recovery of heavy oil are detailed compares the introduction, summarizes the technical characteristics, thick oil layer mining technology present situation and future development trend. Key words：The heavy oil thermal recovery; Thermal insulation pipe string; Layered production; Cold sand mining; 2.5 完井技术..................................................... 2.5.1 沉砂口袋............................................... 2.5.2 完井方式............................................... 2.5.3 射孔方式............................................... 2.5.4 射孔压力............................................... 2.5.5 射孔井段...............................................稠油在我国的石油资源中所占比例较大，其开采技术一直是石油界探索的问题隔热油管蒸汽、地下开采说明工具之一、孤立油管说明蒸气有更多的机会来改善抵达油层,利用程度,这使得她们能够防止生产油井大火的污染物,套管和水泥、歪曲特制的使用寿命。随着轮次剥削移民、减少燃料取暖和基础,压力下降,越来越少的产量降低蒸气、石油开采技术的吞吐原产地监测普遍准入在运行阶段、无效或无效吞吐油藏中。因此,寻求新的研制、生产、新吞吐石油矿床后一个紧迫问题。蒸汽开发改善获得驱虫蚊帐,他们可以有效石油矿床的开采阶段会议缉捕、改善产出突出效果。 1-1： 表 1-1 各个国家油藏参照表 国家 油田 相对密度 杂原子含量（%） 胶质沥青（%） S O N 胶质 沥青 中国 辽河高升 0.94-0.96 0.55 — 0.72 42.5 3.3 新疆风城 0.9656 0.31 — 0.51 56.7 5.7 加拿大 Athabasca 1.015 4.6 1 0.5 23.4 18 Cold Lake 0.994 4.5 1.5 0.4 28.3 15 Peace River 1.026 5.9 1.6 0.5 30.5 19.5 委
