国内外油田目前大多将防砂、堵水措施分开实施 ,大大增加生产成本。研究将防砂堵水工艺合二为一的新型防砂堵水剂 ,既能有效防砂 ,又有选择性堵水效果。通过正交试验方式 ,优化选择出以改性有机硅树脂为胶结剂主要成分的防砂堵水剂配方 ,根据试验结果评价其防砂及堵水性能 ,现场试验证实防砂、堵水效果良好。
At present, most domestic and overseas oilfields will implement sand control and water blocking measures separately, which will greatly increase the production cost. Research sand control technology will be combined into a new sand control plugging agent, both effective sand control, but also selective water blocking effect. Through orthogonal test, the sand control and water plugging agent with the modified silicone resin as the main component of cementing agent was optimized. The sand control and water plugging performance were evaluated according to the test results. Field tests confirmed that sand control and water plugging effect were good.
