OYJG深部封窜剂的性能研究及应用

针对中低渗透油藏注水开发过程中普遍存在含水上升速度快、油井过早水淹的实际情况，研制出易进入地层深部、耐温80-150℃、耐盐10000mg／L的OYJG深部封窜剂。该封窜剂可堵可解，对非均质较高的岩心具：肓深部调剖改流的能力，可作为调剖剂或堵水剂。该封窜剂在河口采油厂渤南油田进行凋剖试验，获得良好的应用效果。

Evaluation and Application of OYJG Plugging Agent

Due to the situation of quickly rise of water cut and early breakthough in prodution wells, a plugging agent OYJG was developed. It could keep steady at the temperature 80 - 150℃ ,and at the salinity about 10 000 mg/L,and it was easy to be injected into formations. OYJG was resolvable,and it had the ability of deep profile modification and fluid modification in the cores with serious heterogenity, so that it could be used as profile modification agent and plugging agent. OYJG had been used in Bonan Oilfield of Hekou oil production factory, and had achived good results.
