复杂小断块老油田稳产技术研究

The Study of Stability Oil Production Technique in the Old Oilfield with Complicated Small Fault Block

针对江苏油田储层的严重非均质和复杂小断块的地质特点,在稳产过程中,通过油藏精细描述、构造精细解释、剩余油分布规律认识等研究,采取滚动与调整相结合的思路。一方面增加地质储量,另一方面利用多种工艺技术,最大限度地改善高渗层剖面,挖掘中低渗透层潜力,提高开发水平。这些技术的综合应用,有效地控制了油田递减,实现了老油田的硬稳定。

In accordance with strong heterogeneity and geological characteristic of the complicated small fault block reservoir in Jiangsu oilfield, with the study of the reservoir finely description, constructing finely hermeneutically and the knowledge of distributing regulation of surplus oil, we adopt the meaning of roll over and adjustment together. One hand, we increase the geology reserves, on the other hand, we make use of many craft technique to improve section of high permeable layer with the biggest limit, and to tap the potential of mediumlow permeable layers to improve oilfield development level. Synthesizing application of these techniques gradually controlled the decrease of the oilfield, and realizes its stability.
