浅层常规稠油油藏筛管完井水平井高含水综合治理技术
Precise Treatment Technology of Screen Completion Horizontal Well in High Water Cut Stage in Shallow Conventional Heavy Oil Reservoir

本文针对冀东油田浅层边底水常规稠油油藏筛管完井的高含水水平井采用常规工艺无法降低含水的问题，分析了油井高含水和后期治理措施失效的原因，开展了高含水段和低含水段之间ACP有效的分隔技术、利用ACP提供的井筒条件下对高含水段深部封堵技术、对低含水段的二氧化碳吞吐技术研究，形成了浅层常规稠油油藏筛管完井水平井高含水综合治理技术，现场实施见到较好的效果。
In this paper, aiming at the problem of high water cut horizontal well in conventional heavy oil reservoir with shallow and bottom water in Jidong Oilfield, which can’t reduce water cut by adopting conventional technology, the reasons of high water cut and failure of later treatment measures are analyzed; the effective separation technology of ACP between high water cut section and low water cut section is developed; the deep plugging technology of high water cut section and low water cut section under the well bore condition is provided. The research of carbon dioxide huff and puff technology in water cut section has formed; the precise treatment technology in high water cut stage of screen tube completion horizontal well in shallow conventional heavy oil reservoir has formed; and the field implementation has achieved good results.
