为了研究不同类型油藏水平井完井方式的适应性,结合辽河油田不同油藏类型水平井完井技术现状和现场应用情况,分别对巨厚稠油水平井完井结构和注汽效果、严重出砂水平井完井结构和防砂效果及薄层边底水稠油油藏和薄层边底水稀油油藏水平井的完井方式进行了分析和评价,优选出了适用于不同油藏类型水平井的最佳完井方式,对于提高辽河油田水平井开发效果具有十分重要的现实意义,可以作为水平井完井方式选择的参考。

According to the status quo and the field application of horizontal well completion techniques in various reservoirs of Liaohe Oilfield,this paper analyzes and evaluates the completion structure and steam injection effect of huge thickness viscous horizontal wells,the completion structure and sand control effect of severely sanding production horizontal wells,and the completion methods of horizontal wells in heavy oil reservoirs with edge and bottom water and thin oil reservoirs with edge and bottom water to analyze the adaptability of horizontal well completion methods applied in different reservoirs.The optimum well completion method selects that can be applied to various types of oil reservoirs is selected.This is very important for improving the development result of the horizontal wells in Liaohe Oilfield and can be referred as a good selection to horizontal well completion methods.
