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

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.
