摘要
随着油田进入高含水和特高含水开发阶段,小层间物性差异变大,注水管柱上的沾污、大孔道严重等影响,同位素载体示踪法测井资料的准确性变差。针对用同位素载体示踪法测井遇到的封隔器密封、封堵、套管漏失等问题,解释结果不能定量地给出结论,通过连续示踪相关测井利用液体示踪剂无微球载体、粒径远小于地层孔隙、进层快、且可以定点释放定点测量的优势,测井原始曲线幅值明显,可以定量反应封隔器是否密封、封堵层是否吸水等问题,为用户提供更加全面、准确的测试资料,能够满足目前油田的测试需求。
As the field entered high water cut development stage,the accuracy of isotope carrier tracer logging data deteriorates due to the large difference of small interlayer,contamination of water injection column and serious big pore. For packer encountered by isotope tracer method,the log carrier seal closure,the results cannot get the quantitative conclusions refereeing to such problems as casing leakage,packer sealing,etc. Through continuous tracer associated with a liquid tracer logging without microsphere carrier,the particle size is much smaller than the pore,can get into the layer faster,and can release point advantage point measurement. The original logging curve amplitude obviously,and can be quantitatively react the issues such as whether the packer sealed,or whether water layer blocked. It can provide users with a more comprehensive and accurate test data to meet the current needs of the oilfield.
