摘要
RMT在反映油层水淹程度、指示产层出砂、识别含气层位、识别油水界面、确定堵水层位和再挖潜老井等方面获得了较好的效果。通过对RMT仪器在取心井的测井解释结果分析以及多年的现场应用总结,探讨了影响RMT测井资料准确性的因素。分析结果表明,C/O测井方法在厚层评价方面符合率达80%以上,薄层是影响解释精度的主要因素。RMT测井在地层厚度满足的条件下,孔隙度〉12%时,解释结果可靠;孔隙度在10%~12%之间,解释结果具有参考价值;孔隙度%10%时,解释结果应慎重应用。另外,多层合层、厚层未细分也影响RMT测井定性解释结论的准确性。为测井资料的准确应用提供了依据。
RMT (Reservoir Monitor Tool) obtained good results in some applications, such as reflecting degree of reservoir flood, indicating sand production, identifying gas-bearing formation, identifying oil water contact, determining the water shut-off zone, and re-tapping old well potential. On the basis of log interpretation results analysis in core holes and multi-site applications of RMT logging, discussed are influence factors of interpretation accuracy of RMT logging. Analysis results show that interpretation agreement rate is more 80% to thick layer evaluation with C/ O log method, thin layer is main factor affecting interpretation accuracy. Under the condition of layer thick meeting the requirement in RMT log, when porosity is above 12%, the interpretation results are reliable;when the porosity is between 10% and 12 %, the interpretation results may be a reference; when porosity is blow 10%, the interpretation results should be carefully applied. On the other side, multi-layer assemble and thick layer un-subdivision are also factors affecting interpretation accuracy of RMT log. The analyses provided the basis for accurate logging data application.
