针对苏里格气田苏某区块砂体规模小、厚度薄、埋藏深、物性差、非均质性强等复杂的地质特征,为提高Ⅰ+Ⅱ类井比例,实现区块科学有效开发,提出了地质与地震相结合的优化布井新技术。按照“有利区筛选,有利井位布署,根据实施效果进行井位调整”的技术思路,在主河道刻画的基础上综合分析沉积作用、粗岩相展布、溶蚀孔隙发育段的分布情况,进行有效储层展布的研究,并在此基础上结合储层物性优选和生产动态优选确定产建有利区,然后通过区域有效储层展布和物性研究并结合AVO分析和波形分析优化布署井位,最后根据实施效果对井位进行调整。
In view of the complex geological features such as small size, thin thickness, deep burial, poor physical properties and strong heterogeneity of the sand body in Sumou block of Sulige gas field, in order to improve the ratio of Ⅰ + Ⅱ type wells and realize the scientific and effective development of the block, Put forward the new technology of the combination of geology and seismic optimization of well. According to the technical ideas of “favorable area screening, favorable well location deployment and well location adjustment according to the implementation effect”, based on the characterization of the main channel, the distribution of sedimentary facies, coarse-grained facies distribution and dissolution pore development stage are comprehensively analyzed Based on this, the favorable areas for production are determined based on the optimization of reservoir physical properties and production dynamics, and then optimized by the effective reservoir distribution and physical properties of the area combined with the AVO analysis and waveform analysis Well site layout, and finally according to the implementation of the effect of well position adjustment.
