虎狼峁区属于典型三低油藏,储层物性差,水驱状况不均,单井产量低,由于区块本身复杂低渗油藏地质特征,伴随着油田投入注水开发,虎狼峁区呈现部分油井含水上升过快甚至暴性水淹,近几年来虎狼峁区实施了以化学调剖堵水为主的水井剖面治理,提高了水驱效率和水驱动用程度,取得了良好的效果。本文通过对该技术思路及调剖井效果分析研究,在取得了一定认识的基础上,对该技术的应用提出了合理化建议。
Because of the geological characteristics of complex low-permeability reservoirs in the block itself, with the development of the injection into the oilfield, the area of tiger wolf is present as a part of a typical three-low oil reservoir with poor reservoir properties and uneven waterflooding conditions. In recent years, the area of well control with chemical profile control and water plugging has been implemented in the Wolong district, which has improved water flooding efficiency and water-driven utilization and achieved good results. Based on the technical ideas and analysis of effect of profile control well, this paper puts forward reasonable suggestions on the application of this technology based on a certain understanding.
