克拉玛依油田八区克上组砾岩油藏测井描述

克拉玛依油田八区克上组储层发育,油气资源丰富,为克拉玛依油田八区的主力油藏.在该油藏研究中,充分利用已有的测井资料,首先研究了测井资料的标准化方法和以测井曲线为基础的岩心归位方法,进而采用神经网络技术将测井信息转化为地质信息,通过该区117口井资料的综合解释和评价处理,为储层研究提供了基本地质参数和油气评价结论,并采用克里金估计模型绘制了砂体分布、油层有效厚度、孔隙度、渗透率及含油饱和度的平面空间分布图,全面分析了储层在空间的分布规律,为区块油藏综合治理和开发提供了可靠依据.

RESERVOIR DESCRIPTION OF KESHANG FORMATION OF BLOCK 8 IN KELAMAYI OIL FIELD ACCORDING TO LOG DATA

The Kelamayi Oil Field has well-developed reservoirs and abundant oil and gas at Block 8 in the Keshang Formation. Firstly the well log is generalized and the core positioned. The information delivered from logs is then transformed into the geological information by using of neural network technology. Thirdly, the data from 117 wells are comprehensively analyzed and appraised. The basic geological parameters are worked out for the reservoir research. Finally, based on the Kriging method, the relative maps, such as sand body distribution, affective thickness of the pay zones, porosity, permeability, oil saturation and so like, are made. The distributions of the reservoirs are spatially analyzed, which provide a reliable basis for the field development and the reservoir management.
