[Abstract]:Based on the physical basis of seismic reservoir inversion and oil and gas detection, this paper calculates and analyzes the application of Gassmann theory and BISQ theory, and puts forward the applicable scope and limitation of each theoretical calculation. According to the field practice and practical deduction, it can be found that the Gassmann equation can be used in the wave velocity measurement of seismic data (100Hz) and logging data (104Hz). For the laboratory ultrasonic data, the application range of Biot theory is limited to saturated rocks with large porosity and permeability. When uneven localized flow of pore fluid occurs in rock, Biot's theory will no longer be applicable to the theory of "local flow", and BISQ's theory should be adopted as a partial solution of the effect of pore fluid. The theory and equation of more accurate solution or complete solution need to be further studied and developed. The research project of seismic oil and gas detection processing and prediction in E oil field is based on 3D seismic data and applies Biot dual phase medium model oil and gas detection technology. Development of oil and gas detection processing and reservoir hydrocarbon bearing prediction for four target layers of Carboniferous in E Oilfield. Seismic oil and gas detection processing and prediction research project of E Oilfield completed Biot double layers of 55km2 3D seismic data in E Oilfield Oil and gas detection and processing in phase media model and prediction of oil and gas distribution. According to the oil and gas detection results, combined with the research results, the comprehensive evaluation of the two reservoirs is carried out, and a favorable oil-gas prediction area is proposed.
