随着油田开发水平井越来越多,在水平井冲砂施工也逐步增多,现采油五厂还几乎没有一种较成功的施工工艺,有效的提高水平井的冲砂施工效率。为解决以上问题,我大胆改进水平井冲砂管柱结构,研制加工新型涡流工具和油套液流变向组合工具,冲砂中运用这两种工具相配合,选用合理的冲砂参数、方法,有效提高工作液的冲洗与携带能力,冲砂效率得到提高。
With the increasing number of horizontal wells in oilfield development, sand flushing construction in horizontal wells has also gradually increased. There is hardly any successful construction technology in No.5 Oil Production Plant, which effectively improves the construction efficiency of horizontal wells. In order to solve the above problems, I boldly improve the horizontal well flushing string structure, development and processing of a new type of eddy current tools and oil flow steering combination tool, red sand using these two tools to cooperate, the selection of a reasonable red sand parameters, methods , Effectively improve the working fluid washing and carrying capacity, red sand efficiency is improved.
