摘要
介绍了大港油田在开发官 10 9- 1断块特稠油油藏时的一些有益尝试 ,包括采取复合增效射孔技术提高射孔完善程度 ,实施化学吞吐提高地层内稠油的流动性 ,强化有杆泵举升工艺配套 (应用皮带机采取长冲程低冲次的工作制度、优化杆管柱结构、配套环空掺水加药降粘 )等 ,最终走综合配套的路子 ,实现了对官 10 9- 1断块的动用 ,突破了热采开发同类油藏的工艺配套模式 ,为类似油藏的开发探索了一条新路子。
The article introduce some beneficial attempt to exploit extra-viscous oil reservoir in Guan 109-1 block of Dagang Oilfield, which include composite benefit increasing perforation technology to enhance perforated improvement degree, reinforce the flowability of viscous oil in strata by means of chemical swallow and spit technique, strengthen the match of lifting technology with rod pump utilization of belt unit with running regulation of long stroke and slow stroke frequency, optimization of tube string str...
