| 摘 要： | 根据经验，聚合物驱后组合驱在注采井网井距问题上可参考聚合物驱井网井距的研究方法。由于油田实际资料表明吸水、产液指数相差较小，因此组合驱选择五点法面积井网较为合理。又由于组合驱井网井距大小主要影响聚合物的热降解情况，因此可根据化学剂在地层中的粘度-浓度关系、水解增粘规律、剪切降解及热降解规律，可求得组合驱中不同浓度聚合物段塞在注入地层不同时间后的粘度；再结合不同井距下组合驱驱替液流动速度及见效时间，并考虑注入能力、采液能力以及油层渗透率与注采井距的关系，即可得到组合驱井距的合理范围。

| Abstract: | Based on experience, well pattern and well space were determined by referring the method of determining well pattern and well space in polymer flooding. Because of production data indicating water absorption and fluid production coefficients were less, it was rational to use a five spot pattern for combination oil displacement. Also because the pattern size of the combination displacement influenced thermal degradation, the viscosity of plug of polymers with different concentrations injected in different ti... |
