影响吸水剖面测井资料准确性的因素及对策

Factors Influencing the Accuracy of Well Logging Data of Injectlvity Profile and Its Counternuasures

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 。

Because of the factors of isotopic contamination, unreasonable pipe structure of water injection wells, existence of big pore formation,cement channeling and poor well performance, the well logging data of injectivity profile accuracy is influenced. In order to improve-the accuracy, a match investigation of particle size and density of isotope microsphere is made, by which the pipe structure of water injection well is improved. A contamination-correct interpretation and an integrated interpretation are also carried out.
