E Oilfield By Using The Seismic Method Detection Mechanism And Prediction Of Oil And Gas Research

Based on the seismic reservoir inversion and hydrocarbon detection on the basis of physical,to the current popular Gassmann theory,Biot theory and applicable to the calculation analysis of BISQ theory,the scope of application and limitations of each theory computing;In view of the field practice and actual deduction shows:(1)Gassmann equation can be used in seismic data(< 100 hz)and logging data(~ 10 ~ 4 hz)wave velocity measurEent,ultrasonic measurEent data for laboratory(~ 10 ~ 6 hz),use less as far as possible;(2)the Biot theory application scope is limited to large porosity,permeability of saturated rocks,when the rock pore fluid in the localization of non-uniform flow occurs,will no longer apply Biot theory,BISQ theory give full consideration to the local flow effect,BISQ theory should be adopted;(3)Gassmann equation,the Biot theory and effects of pore fluid is only part of the solution of BISQ theory,a more accurate solution or complete solution theory and equation,still need further research and development.E field seismic detection of oil and gas processing and prediction research project is based on 3 d seismic data,the application of Biot two-phase medium model of oil and gas detection technology,in view of the E field four purpose layer in the carboniferous oil and gas detection processing and oiliness of reservoir prediction.E field seismic detection of oil and gas processing and prediction research project completed the E field of 55 km2 two interval of 3D seismic data of Biot two-phase medium model of oil and gas detection processing and oil and gas distribution prediction research.Based on the results of oil and gas detection,combined with the research results of two reservoir comprehensive evaluation,put forward the favorable oil and gas prediction area.
