Research On Logging Evaluation Method Of Jimsar Shale Oil Reservoir Quality

The Jimsar sag located in Junggar basin has abundant oil and gas resources,abundant shale oil reserves and great exploration potential,and its shale series has two oil-bearing systems up and down,source and storage,and integral oil-bearing.However,reservoir lithology and mineral composition are complex and changeable,and there are many transitional rocks in clastic and carbonate rocks,and the porosity and permeability are very low,so reservoir evaluation has been very difficult.Reservoir quality is a key parameter describing the productivity of the reservoir,and it is a comprehensive reflection of the reservoir lithology,physical properties,permeability,etc.If you find the relationship between the reservoir quality parameters and productivity,you can evaluate the page Rock oil reservoir.This paper starts with the basic characteristic parameters of shale oil reservoirs,specifically analyzes the lithology,physical properties and oil-bearing characteristics of the reservoir;and comparatively analyzes the logging response characteristics of conventional logging methods and nuclear magnetic logging methods.Logging for further research.In this paper,the core quality experiment data and nuclear magnetic logging data are used to establish a reservoir quality index calculation model,which clarifies the relationship between reservoir quality index and productivity.And on this basis,establish a reservoir classification standard suitable for the area.Through the verification of the actual logging data processing,it is found that this method has a good application effect in the reservoir evaluation of the study area,which can help the exploration and development of shale oil in the study area.
