摘要
Abstract
RCH logging technology focuses on carbon and hydrogen ratio in the stratum to get the oil saturation,which mitigates the effect of porosity and is free from the limitation of salinity. The authors analyzed and identified the relation between the RCH and oil saturation according to the conclusions of the RCH interpretation and oil testing of 15 wells of five reservoirs types, as well as the data on hermetic core oil saturation. the analysis revealed that the oil saturation,rather than porosity has the prominent effect on the RCH,which changes along with oil saturation changes;The conclusions of the RCH interpretation and oil testing are accurate,credible and of good correlation. The test on the five reservoirs types indicated that the RCH can evaluate waterflood degrees and the residual oil saturation effectively. It can provide reliable data in searching missing oil reservoir and providing measures of water plugging as well. Besides,the RCH can be widely-used in sand shale profile. It has a remarkably geological effect in sand,mud or low resistance oil reservoir.关键词
