基于三维定量荧光技术的东海盆地储层复杂流体性质快速识别方法
A rapid identification method of complex fluid properties of reservoirs in the East China Sea Basin based on 3D quantitative fluorescence techniques
摘要
Abstract
The main exploration activities in the East China Sea Basin are concentrated in the Xihu Sag and Lishui Sag.Various types of reservoirs,such as oil reservoirs,gas reservoirs,and CO2 reservoirs,have been dis-covered in the basin.The reservoir fluids are complex,making it difficult to identify their properties quickly.By analysing a large number of 3D quantitative fluorescence spectrum characteristics and key parameters of more than 60 explorational wells in the basin,it was found that the intersection characteristics of the two key paramet-ers:fluorescence contrast level and oil index are significantly related to the reservoir fluid properties.Based on the results of well logging and well tests,this paper establishes the interpretation diagram and interpretation table of reservoir fluid properties in different blocks of the East China Sea Basin.This method is convenient for obtaining on-site data.It can not only quickly identify conventional petroleum reservoirs and aquifers,but also efficiently and accurately identify complex fluid properties such as high-resistivity aquifers,low-resistivity gas reservoirs,and low-permeability gas reservoirs.The evaluation results are consistent with well logging and test results.This method has been applied successfully during well drilling processes and is worth promoting.关键词
