无机凝胶调剖体系具有耐温抗盐性好,且基液粘度低,注入性能好,成胶后在高温高盐条件下的堵塞能力强等特点。在对无机凝胶调剖体系进行全面的静态和动态性能评价的基础上,分析体系的油藏适用性,经过在中原油田卫22断块高温、高盐中低渗油藏的应用,取得了较好的增油降水效果。
Inorganic gel profile control system has the characteristics of good temperature and salt resistance, low viscosity of base fluid, good injection performance and high clogging ability under high temperature and high salt condition after being gelled. Based on the comprehensive static and dynamic performance evaluation of the inorganic gel profile control system, the reservoir suitability of the system was analyzed. After the application of the high temperature and high salt medium-low permeability reservoirs in Wei22 fault block of Zhongyuan Oilfield, Better oil precipitation effect.
