新型防砂堵水剂的研制与应用

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。表6参5（王任芳摘）

Development and application of a new type of sand prevention and water plugging agent

Sand prevention and water plugging are two major measures for maintaining the plateau oil production of an oil field. Some oil wells need to plug water further after the sand prevention measure was done, which leads to increasing the cost of oil production. Therefore a new type of sand prevention and water plugging agent was studied in this paper. The new agent can prevent sand effectively, but also plug water with high selectivity. An integration of sand prevention with water plugging can be realized, which greatly increase the economic benefit of oilfield development. The formulation of sand prevention and water plugging agent was obtained from orthogonal test. The sand prevention and water plugging properties of the new agent were evaluated in laboratory and a satisfactory result was gained from field tests.
