Underground Reservoir Architectural Elements Analysis on Minghuazhen Formation of Gangxi Oilfield, Eastern China

Abstract:

Neogene Minghuazhen formation of Gangxi oilfield is a sequence of meandering river sedimentary record, which consists of a series of upward fining succession. During the mid-later period, it is becoming more difficult for oil development because of strong reservoir heterogeneity. In the late stage of oilfield development, it is necessary to refine temporal and spacial distribution of sedimentary facies distribution. Based on sedimentary facies research, the paper put focus on architectural elements analysis of meandering river point bar reservoir, mainly using underground well logging data. By the way of calculations of typical well area (Gx47-4) of Nm2-7-1 single layer, the scale of lateral acceleration sandstone body, the dip angel of lateral mudstone interlayers, the ratio of the width and thickness of channel sandstone are quantitatively calculated. The results show that the dip angle of lateral accretion interlayers within a point bar is 4-6° and the ratio of width and depth of a meandering river is 18-22 and the planar width is about 50m. These quantitative parameters provide important foundation for next detailed study on sedimentary features of underground reservoir. At the same time they provide significant guidance for well pattern adjustment.
