Prediction Of Distribution Law Of Potassium Rich Brine In Triassic In Northeast Sichuan

There are relatively few studies using "multi-discipline,multi-angle,multi-method" in potassium-rich brine water resources.In recent years,breakthroughs have been made in the research of potassium-rich brine water resources at home and abroad.However,at present,through the combination of well logging response characteristics and seismic related attributes inversion,the prediction of the distribution law of potassium-rich brine is still in the initial stage,which also has a certain impact on the exploration of potassium-rich brine resources..Therefore,to strengthen the research on the distribution law of potassium-rich brine,it is necessary to effectively use the comprehensive methods of geology,logging and seismic,which is of great significance for the development of potassium-rich brine water resources and alleviating the pressure on my country's potassium resources.Through the integration of geology,logging and seismic integration,the study of the distribution of potassium-rich brine in the northeastern Sichuan Basin can provide a theoretical basis for the distribution of potassium-rich brine in the Sichuan Basin.Combining research methods and methods such as geology,logging,and seismic,and researching through oil and gas drilling,newly drilled potassium-rich brine wells,field outcrops,and 3D seismic data,the main research results are:1.Through petrological analysis of cores and field profiles,carry out sedimentary paleoenvironment research of the Jialingjiang Formation and Leikoupo Formation,and determine that the key salt-forming period of the Triassic in the northeastern Sichuan region was formed in the limited carbonate-evaporation platform sedimentary system The gypsum salt basin is the most favorable sedimentary microfacies for the development of potassium-rich brine,and the lithofacies paleogeography map of the key salt-forming period has been drawn to clarify the most favorable period for the formation of potassium-rich brine and the potassium accumulation area.2.Collect logging data from each well,analyze the physical characteristics and differences of main reservoirs,and provide reference or calibration basis for the processing and interpretation of geophysical data in this area.By collecting relevant data such as natural gamma,sonic jet lag,resistivity,density,etc.,establish a rendezvous graph,find the law,and establish a log identification mark for potassium-rich brine.3.Through the combination of well-seismic data,develop the layer and structure interpretation of 3D seismic data,and use the multi-parameter inversion technology of artificial intelligence to perform a more refined characterization to predict the spatial distribution of potassium-rich brine in northeastern Sichuan.
