摘　　要：以曙一区杜84断块曙1-38-7030井组为例,系统地论述了利用多共整体蒸汽吞吐技术改善超稠油开发效果的原理及开发程序。通过对多井整体蒸汽吞吐机理的研究,综合分析了该项技术在超稠油开发中的可行性和必要性,提出实施的前提条件和具体的操作程序,在生产实践中见到了明显效果。实践证明,多井整体蒸汽吞吐是改善超稠油中、高轮次吞吐效果的主要手段之一,为辽河油区超稠油油藏以及其它地区类似油藏的开发提供了借鉴。Taking well block Shul-38-7030 in block Du84 of Shu1 area as an example, this paper systematically discusses the theory and development procedures for improving super heavy oil recovery through multi-well cyclic steam stimulation. Through studying the mechanism of multi-well cyclic steam stimulation, the feasibility and necessity of using this method in super heavy oil development are comprehensively analyzed, the preconditions and specific operation procedure are put forward, and obvious effectiveness has been seen in production practice. Practice shows that the multi-well cyclic steam stimulation is one of the major measures of improving the effectiveness of super heavy oil steam stimulation in medium and latter cycles. This provides a reference for developing super heavy oil reservoir in Liaohe oil province and similar reservoirs of other areas.
