摘要
针对中原油田地质情况复杂 ,油藏埋藏深 ,高温、高压低渗 ,温度与矿化度高 ,储层非均质性严重的特点 ,研制开发了 YH2 0 0 0高强度复合堵剂 ,该复合堵剂是把凝胶堵剂和树脂堵剂有机结合 ,现场工艺成功率和封堵成功率均达到了 1 0 0 % ,取得了明显的增油降水效果 ,该堵剂的研制成功 ,基本解决了中原油田高温、高压、低渗透油藏的堵水作业 .着重阐述了该堵剂的研究思路、室内筛选和评价方法以及现场应用情况 .
The reservoir in Zhongyuan Oilfield has the characteristics of great buried depth, high temperature and pressure, low permeability, high salinity and serious heterogeneity. In order to suit the characteristics, high strength composite plugging agent YH2000 was developed. The research thought, laboratory screening and evaluation method, and field application of the plugging agent are stated. In fact, the plugging agent is the organic combination of gel plugging agent and resin plugging agent. The field applications show that the success ratioes of both construction and plugging reach to 100%, and the effectiveness of increasing oil output and inducing water cut is obvious.
