For the rolling development of gas field,provide the basis for the division of the Malibu wells region,the northern Songliao Basin Xujiaweizi depression for Shengping gas field target area,improve the quality of seismic data processing in the field of 3D seismic data acquisition on the basis of 1996-1997 years,the comprehensive application of synthetic seismogram and VSP data of single well and multi wells the calibration,research 1X1 measuring network density of fine interpretation.At the same time,we carry out the comprehensive prediction research in the study area,summarize the attributes suitable for the geological characteristics of the area,and predict the fracture development zones by using the seismic method.The final comprehensive description of reservoir fine description of gas reservoir by gas,gas and water distribution,establish fine 3D relationship between water and gas prediction model,relationship,effective reservoir structure and effective reservoir and sedimentary microfacies,the fine description of effective reservoir and fault relation,summed up the accumulation and effective reservoir distribution of gas reservoir blocks,and submit the favorable target area and location. |
