摘要
塔河油田六区中下奥陶统碳酸盐岩储层储集空间复杂,主要为裂缝和溶蚀孔、洞,正确分辨出储层类型及其发育层段,对于油气勘探和开发具有重要意义。在分析各类储层测井响应特征的基础上,对储层首先采用交会图法进行定性识别,然后采用多元判别方法进行定量识别,研究成果表明,应用本文提供的方法,可以对塔河六区各夹储层进行分类识别。
The distribution of reservoir in lower Tahe 6 block Ordovician carbonate formation is quite complicated which consists of fissure,pore and cave.Correctly identifying the pay zone and its potential interval is the focus of ex- ploration and development in this block.On the basis of log characteristics of major reservoirs,Cross Plot method and Multi-dimensional Diseriminant method are adopted to carry out quantitative identification.The application in Tahe oilfield shows that satisfying results are received from reservoir identification.
