The Fine Reservoir Description In The Northeast In Huangjindai Oilfield

In this paper, "fine reservoir description"technology as the guide, comprehensive application of sequence stratigraphy, seismic stratigraphy, reservoir stratigraphy, geological statistics and other methods of stratigraphic classification and correlation, sedimentary characteristics and depositional system to carry out research to find out storage Layer and reservoir distribution. Fine structural interpretation by 3-D technology, implementation of the structural formation mechanism and structural features to determine the tectonic evolution. At the same time according to the water distribution in the area, analysis systemly on forming rules and controlling factors.As well pattern no perfect of sand-1 section, and mining levels of sand-3 section, therefore, the main purpose formation of this study is to sand-1 section, and to take into account sand-3 section oil and gas reservoir. The paper carried out from the formation comparison and three-dimensional seismic interpretation work, at the same time, analysis and research sedimentary conditions, litho faces type, sedimentary structures, granulometric characteristics and sedimentary features of Huangjindai oilfield. The sedimentary phase can be classified in the Sand-1 section in term of the sandstone group. The sedimentary revolutionary laws can be analyzed according to the regional geological phenomena and sedimentary condition of Sand-1 section. The lithological characteristics of reservoir, physical characteristics, non-uniform, distribution characteristics and connectivity, properties were studied.The purpose was inversed with Jason program in this area, so that the vertical and plane distributions have been cleared. Crude oil reserves in the area were re-calculated based on the analysis and study of the oil and gas distribution, controlling factors of oil and gas distribution, oil and gas reservoir type, fluid characteristics.
