Research for the Method of Interpretation and Evaluation of Water-Flooded Layer and Logging in Daqing, La-sa-xing Oilfield

Abstract

Based on sealing coring analysis data and the commissioned well's sidewall coring analysis data, we took the sidewall coring's rock pyrolysis, saturated hydrocarbon gas chromatography, and fluorescent microgram analysis as technological means. Meanwhile, we emphasized on the evaluation of the thick reservoir and thin-poor layer to establish the method of interpretation and evaluation of water-flooded layer and logging in la-sa-xing oilfield. It doesn't not only raise the application level of logging data, but also the delicate evaluation level of thick reservoir. Moreover, it has provided interpretation basis for the development, layer selection and perforation of thin-poor layer while secondary and tertiary infilling is going, which dramatically enhanced the development results of thick reservoir and thin-poor layer.
