Western Sichuan Depression Luodai Suining Formation Tight Gas Well Logging Parameters And The Gas Layer Recognition Research

The reservoir character, gas reservoir recognition, log model and parameter are comprehensively researched by using multi-data of Suining formation in Luodai gas field, which include well-logging, test and lab analysis data etc. According to the abundant test data, the paper study on using of the test data, the well data and lab data to recognize the industry gas reservoirs firstly. With differential porosity methods, the result is better to identify the gas reservoirs and the study gets the model and standard of gas recognition. This text analyses integrated the Interpretation model and parameter of well base on the log data, the rock data and the past's research result. Especially, comprehensively research for the parameter and model of water saturation use the litho-electric experiment data firstly, which under the normal temperature and presses or high temperature and presses condition. It is firstly pointed out that the standard of differential porosity methods is the standard of lower limitation of net pay thickness. In addition, the works of the reservoir character, Well Logging Data Standardization, core parked, the flat surface analysis etc. are studied also. And 125 well are measured with the log integrated interpretation by the paper's result.
