摘要
麦盖提斜坡玉北1井区奥陶系碳酸盐岩储层储集空间复杂,主要为裂缝和溶蚀孔、洞,正确分辨出该区储层类型及其测井识别特征对于油气勘探和开发具有重要意义。以岩心、钻井、录井、测井等资料为基础通过测井响应特征进行综合分析,得出该区存在裂缝型、裂缝—孔洞型、溶洞型3类储层,然后在各类储层测井响应特征的基础上采用纵横波比值法和交会图法对储层进行定量识别。
For the Ordovician carbonate-rock reservoirs in Yubei 1 well block, Meigait Slope, their reservoir space, which mainly consists of fracture, and corrosive pore and vug, is very complex.So, it's significant to identify these reservoir types and their welllogging characteristics for oil and gas exploration and development.On the basis of some data from core analysis, drilling, mud logging,and well logging, the carbonate-rock reservoirs were comprehensively analyzed by well-logging response. Results show that there are three reservoir types, including fractured, fractured-vuggy, andvuggy ones. In addition, the qualitative identification was implemented by P- and S-wave ratio and crossplot methods.
