寻找多油层油藏、底水发育油藏纵向剩余油富集规律,方法简要介绍过套管电阻率测井的测量原理,对这一生产测井技术在安塞油田的测井成果进行分析评价。结论CHFR测井可反映地层纵向剩余油分布状况,为下步剩余油挖潜提供依据。 Looking for multi-reservoir, bottom water development of the reservoir longitudinal residual oil enrichment, the method briefly introduced the measurement principle of the casing resistivity logging, the production logging technology in the Ansai oilfield logging analysis and evaluation . Conclusion The CHFR log can reflect the distribution of residual oil in the longitudinal direction of the strata, and provide the basis for tapping the residual oil in the next step.
