临盘油田分层注水管柱有效率影响因素分析

Analysis of Factors Affecting Separate Flooding Strings Efficiency in Linpan Oilfield

分层注水管柱有效率低一直是困扰临盘油田开发生产的一大难题。针对这一现状,在分析油藏结构、施工工艺和现场资料的基础上,分析了影响分层注水井管柱有效率的因素,阐述了封隔器、工艺操作、管柱自身及温度等制约分层注水管柱有效率提高的原因,并提出了相应的对策和措施。

Low separate flooding string efficiency is one of the main problems in the exploitation of the Linpan Oilfield. Based on analysis of reservoir structures, operation procedure and field data, factors affecting separate flooding string efficiency were analyzed. The reasons prohibiting the increase of separate flooding string efficiency, such as packers, operation procedure, strings, and temperature, etc. are introduced and the corresponding solutions and measures are provided.
