清河采油厂侧钻井效益评价分析

侧钻工艺对于清河采油厂来说是一种新工艺。为了使事故井、停产井、报废井恢复生产,提高原油采收率,同时又能保持所开发井网的完整性,节约钻井成本,减少地面建设费用,清河采油厂充分利用老井场、部分完好的老井筒,通过侧钻新的井眼到目的层位、下入小套管井的方式,使部分报废井、事故井恢复产能。在实践中,还将进一步对小套管内挤堵工艺、防砂工艺、大修工艺进行探讨研究。

On the Efficiency of Sidetracking Applied in Qinghe Oil Production Plant

Sidetracking technique is new to Qinghe Oil Plant.The plant had made full use of obsolete well sites and some old shafts still in good shape by dropping small cased wells through newly sidetracked borehole to the targeted level in order to revitalize some used wells either been blown up or shut down.By resuming production in the once abandoned wells,the plant can raise crude recovery ratio,maintain an intact well pattern and cut the costs in drilling and ground construction.This paper would further explore ...
