高含水期示踪剂及碳氧比测井测定剩余油精度评价

Accuracy assessment of determining residual oil by tracer and carbon - oxygen log in high water cut stage

针对高含水期剩余油分布监测与解释方法开展相关的评价研究。选取目前较为常规的剩余油分布动态监测与解释方法:井间示踪剂监测和碳氧比测井,进行了方法概述和理论分析。并对这些方法的适用性进行了评价研究。通过分析对比各个相关参数对最终解释结果精度的影响,从误差分析的角度,定性评价了两种方法在解决高含水-特高含水时期剩余油监测与解释问题上的可靠程度、主要影响因素和影响程度。

Relative assessment and study have been conducted for the monitoring and interpretation method of residual oil distribution in high water cut stage. Well - to - well tracer monitoring and carbon - oxygen log, which are conventionally used at present, are selected and analyzed. The viability of relative methods is also assessed and studied. Through correlative analysis of the influence of relative parameters on the accuracy of final interpretation result, with consideration of errors, the reliability, major affecting factors and affecting degree of these two methods for residual oil monitoring and interpretation in high water cut - extra high water cut stage are qualitatively evaluated.
