冀东油田古潜山油藏特征及完井工艺探索与实践

通过对南堡油田奥陶系古潜山及南堡凹陷周边古潜山储层特征的研究,结合试油效果分析,初步形成了1套古潜山勘探完井方式的选择原则.研究认为,南堡油田奥陶系古潜山南堡1、2、5号构造适合采用裸眼方法完井,南堡凹陷周边古潜山油藏应采用筛管+盲管或射孔方法完井.根据油气藏不同特点,选择不同的完井方式,以缩短钻井周期、减少储层污染,且要满足后续试油施工的各种要求;工艺技术的进步和地质认识的提高是古潜山获得突破的前提和基础.

Reservoir characteristics and well completion technique of Jidong buried hill

This paper studies reservoir characteristics of the Ordovician buried hill in Nanpu oilfield and the periphery buried hills in Nanpu depression,presents the principles of selecting exploration method and well completion system for buried hill reservoirs in conjunction with analysis of well testing result. The study indicates that the Nanpu 1,2 and 5 structures in the Ordovician buried hill of Nanpu oilfield are candidates of open hole completion,while the periphery buried hill reservoirs in Nanpu depression...
