| 中文摘要: |
| 渤海B油田沙河街组发育低渗油藏,区块间单井产能差异大,优质储层分布规律与分布模式认识不清,制约了该区低渗油田注气方案的编制。本文综合应用录井、测井、岩芯、微观资料及地震信息,从低渗储层成因出发,将“甜点”分为3大类(河道型、河口坝型、席状砂型)；建立了单层顶部型、单层中部型、单层底部型、双层型、多层型等5种“甜点”分布模式；基于相模式的振幅、波形聚类分析,对靶区各油组“甜点”分布进行了预测。本文研究为该油田注气实验区的确定、注气方案的编制提供了有利的支撑。 |
| 英文摘要: |
| In order to develop Bohai B Oilfield by gas injection, it is necessary to solve the problem that the distribution law and pattern of high quality reservoir are not clear. Based on the comprehensive application of logging, core, micro data and seismic information, this paper considers that the distribution of “sweet spots” is controlled by high-quality sedimentary facies. The sweet spots are divided into 3 categories (river channel, mouth bar, sheet sand). Based on the amplitude and waveform cluster analysis of the phase pattern, the dessert distribution of each oil group in the target area is predicted. This study provides a favorable support for the determination of gas injection experimental area and the compilation of gas injection scheme. |
