海外河油田由于构造复杂、储层非均质性强,进入“双高”阶段后,剩余油分布更加复杂,常规的生产测井资料已无法满足动态挖潜需要,而碳氧比测井技术对套管井剩余油监测具有较好的适应性。通过应用碳氧比测井,并结合沉积微相、生产动态分析,深化油田水淹规律和剩余油分布研究,为油田开发调整及油井措施挖潜提供可靠依据。 Due to the complicated structure and strong reservoir heterogeneity, overseas oilfields are more complicated in residual oil distribution after entering the “double high” stage. Conventional production logging data can not meet the needs of dynamic tapping potential. However, The technology has good adaptability to the remaining oil monitoring in cased wells. Through the application of C / O ratio logging, combined with sedimentary microfacies, production dynamic analysis, deepening of the law of flooding and remaining oil distribution, it provides a reliable basis for oilfield development adjustment and oil well tapping.
