Multicomponent seismic survey can provide a variety of information for development of reservoirs, reduce the multiresolution of predicting reservoirs and increase the successful drilling rate. In the past two years, BGP has imported digital seismograph and geophones to research the techniques in 3D and 3-component seismic data acquisition, processing and interpretation, design & demonstration of 3D converted-wave geometry, multiwave uphole survey and surface survey & 3D converted wave static corrections, rotation of horizontal component data & wave field separation, computing 3D common converted bins of converted wave, 3D converted wave residual static corrections, CCP & iterative velocity analysis, converted wave prestack time migration by Kirchhoff integration, horizon labeling of converted wave & P-SV wave and P-wave joint interpretation, using converted wave to analyze physical property of reservoir and predict the lithol-ogy & oil/gas reservoir etc. , forming a complete set of 3-component and 3D seismic technology that has seen a visible effect in application to Sulig Gas Field. Using the 3-componet data to predict gas-bearing character of reservoir made the 4 exploration drillings presented total success. The matching ration of the survey grid with the drilling completion is over 80%.
