Design Of Monitoring System Of Hydrocarbon Migration Experiment Station In Structure Distortion

Physical modeling of hydrocarbon migration, in sand boxes and other experimentalconditions, constructs the experimental environment of hydrocarbon migration and helpsstudy on oil-gas migration and accumulation process according to similarity theory.SandboxModelingisaneffectivewaytostudyonhydrocarbonmigrationanditcanhelpoilgeologists to understand petroleum migration process. At present there is no integratedhydrocarbon migration experiment apparatus in structure distortion, On basis of integratingthe vicarious apparatus in home and abroad, this thesis is aimed at designing monitoringsystemofhydrocarbonmigrationexperimentstationinstructuredistortion.The hydrocarbon migration experiment apparatus is an integrated electromechanicalsystem. On the basis of analyzing the main fault structure phenomenon and origin, thisthesis summarizes the stressing and distorting rule of fault from aspect of dynamics andkinesiology, and brings up the requisite basic functions of mechanics loading unit of theexperiment apparatus. In addition, the concept design of apparatus is carried out, the basicfunctionsandparametersofapparatusareconfirmedaccordingtothesimilarityprinciples.According to the function realized by experiment apparatus mechanical loading unit,the thesis carry out the overall design plan of the electrical control system in detail,including the key technologies of the system. The distributed motion control system basedon programmable controller is developed on the principle of optimization and combination.The electrical system adopts dispersed control as well as concentrated management, whichnotonlyadaptswithexperimentapparatusmodularizedsystembutalsoassurethereliabilityand stability of system. The design achieves the aim of easy operation, convenientmaintenance,easyexpansionandeasyupdate.In order to obtain the dynamic process of hydrocarbon migration in experimentalmodel, this thesis adopts the high-density resistivity method based on Wenner arrangement to detect the original information of hydrocarbon saturation, and establish a model ofresistivity inversion imaging to deal the original information.
