Abstract

Abstract: Due to the small scale, regional geological characteristics and differences in hydrocarbon accumulation conditions, the height of the oil column and distribution of oil and water in secondary fault in developed oilfields with yielding fault sealing evaluation method doesn't conform to the actual drilling. In order to improve prediction accuracy, this study establishing a depth-pressure model with drilling, fluid pressure and other materials, and by fitting the shale gouge ratio (I_SGR) with across fault pressure difference (△p), we determine the quantitative evaluation relationship consistent with regional characteristics, and identify the lower limit of the I_SGR of the fault sealing according to the failure area of the fitted graph envelope. And quantitative judgment of fault sealing ability is made rough comnination of the two methods. The study of the fault block in Area 4 of K Oilfield reveals that the south block in I Formation and the middle block in the upper and lower section of Ⅱ Formation are the same oil and water system. The research are supported by the dynamic of the reservoir.

Key words: Huanghekou Sag, complex fault block, fault sealing, shale gouge ratio, across fault pressure difference
