摘要
为了优选适于0.3×10-3μm2储层最佳井网及开发技术对策、提高单井产量,需要加强地质研究、建立精准的研究区沉积微相模式。从收集到的庄9井区岩心、地质、测井和生产资料出发,按照沉积微相研究内容和要求确定了从单井到剖面、再到平面的研究思路;采用多种沉积相标志确定研究区沉积相划分方案;运用小波分析技术进行地层划分,通过测井相分析、运用灰色关联分析技术、交会图技术进行沉积微相识别,在本区开展沉积微相综合研究。研究成果为该油田提高单井产量措施的优选奠定了坚实的基础。
For the sake of optimizing well network and development techniques to increase the single well production in 0. 3 ×10^-3μm^2 oil layers, strengthening geology researches and building precise sedimentation microfacies are necessary. Based on the core observation, geologic and logging data of Well Z-9, the microfacies study is carried out in the sequence from single well to profile and then to plane. Multiple sedimentation facies markers are used in sedimentation facies division in this region. Then, we study the microfacies pattern by using wavelet technique and grey system technique and cross plot method and log facies analysis and so on. The result of the research fundamentally supported measurements optimization to promote single well production in the region.
