Research On The Adjustment Scheme Of The Long 6 Reservoir Development Ganguyi Oilfield Sha Jia Gou

After nearly 30 years of development, the production of Sha Jia Gou district of Ganguyi oilfield has declined year by year. In order to stable oil production and oil tapping task, the adjustment to the reservoir development program is necessarily.The type of the paper is development research. Chang 6 reservoir of Sha Jia Gou is the reserch object. On the geostatistics theory as a guide, comprehensive utilization of drilling data, well completion logging cruve, scale fracturing, oil production data etc., make full use of the regional tectonic characteristics, sedimentary microfacies, reseroir physical property, heterogeneity and Chang 6 reservoir oil-water distribution on the means. The geogical characteristics of the reservoir were re-understanding.Based on the re-understanding of reservoir geological characteristics, the reservers are calculated, and te geological reserver of he Sha Jia Gou is 620.33×104t. Reservoir development mode is the natural energy exploitation, and the well network density is 33.5/km2. According to the dynamic data of the research area, the oil productiong decline law of the oil field is in accordance with the law of exponential decline, and the fracturing effect is analyzed and evaluated.In this paper, the distribution of the remaining oil is studied from two aspects of the plane and the interlayer. The distibution of the oil is mainly controlled by the reservior heterogeneity and the development factors. According to this studied, the small laryers, that is Chang 611, Chang 612, Chang 613 and Chang 621, is googd of the potential of the remaining oil. And take measures of the reservoir fracturing and well plane.
