新一代的套管井碳 /氧比 (C/O)测井仪能够比以往的仪器提供更多的岩性、孔隙度和流体类型等数据 ,最近的研究工作完善了该项技术 ,使得在油田开发过程中应用套管井C/O测井取代裸眼井测井成为可能。加拿大Alberta的重油砂岩油田用C/O测井。该油田已经进行了一段时间的开发 ,油藏的特点是 ,地层水的矿化度特别低、简单的砂岩地层、中高的孔隙度和侵入比较少的稠油。由于比较清楚地了解油藏的地质结构和岩性 ,对于这样的油田使用套管井C/O测井取代裸眼井测井风险小 ,而且节约投资
A new generation of C / O logging tools can provide more lithology, porosity and fluid type data than previous instruments and recent work has refined the technology to make it easier for oil fields It is possible to use Cased Hole C / O logging instead of openhole logging during development. Heavy Oil Sands in Alberta, Canada C / O Logging. The field has been developed for some time. The reservoir is characterized by extremely low salinity of formation water, simple sandstone formations, medium-high porosity and heavy oil with less intrusion. Due to a clearer understanding of the reservoir’s geological structure and lithology, the use of cased-hole C / O logging instead of open-hole logging in such fields is less risky and saves investment
