由于同位素污染、注水管柱结构不合理、存在大孔道地层、固井窜槽和井况变差等因素 ,影响了吸水剖面测井资料的准确性。为提高其准确性 ,进行了同位素微球粒径及密度的匹配性研究、改进了注水管柱的结构 ,还进行了污染校正解释及综合解释的研究
Due to the isotope pollution, the structure of water injection pipe string is not reasonable, there are large pore strata, cementing channeling and poor well conditions, which affect the accuracy of well logging data. In order to improve its accuracy, the study on the matching of particle diameter and density of isotope microspheres was carried out, the structure of water injection column was improved, the correction of pollution correction and comprehensive interpretation were also carried out
