高温高盐高含水油藏提高水驱采收率配套技术

Matching Techniques for Improving Waterflooding Oil Recovery Factors in High Temperature,High Salt and High Water-cut Reservoirs

针对江汉油区高温高盐高含水油藏的储层条件,应用国内外油藏精细描述、油藏工程最新理论与技术,提出了高含水油田合理钻加密井、完善注采井网、水平井挖潜、不稳定注水及高温高盐油藏采油工艺配套技术措施,形成了一套适应高温高盐高含水油藏提高水驱采收率的配套技术。

In consideration of the conditions of high temperature, high salt and high water-cut reservoirs in Jianghan Oilfield, the description and reservoir engineering, matching techniques for rational infill well drilling, perfecting injection-production well patterns, tapping the potential in horizontal wells, unsteady injection and matching techniques used for high temperature high salt reservoirs are proposed for stimulation in high water-cut reservoirs, a set of matching techniques are established for improving oil recovery in high temperature, high salt and high water-cut reservoirs.
