The Study On Seismic Prediction Technology For Reservoirs Of Triassic Baikouquan Formation In Mabei Slope Area

In recent years, Some oil flow wells obtained in Triassic Baikouquan formation inMabei slope areain XinjiangJunggarBasin. The West wing of Xiazijie fans show it is a whole reservoir group. The discovery show the Triassic Baikouquan formation has good prospect for oil and gas exploration. Baikouquan formation in Mabei slope area is a fan delta sedimentary strata reservoir. The conglomerate reservoir is a Multi-layer in vertical direction. The reservoir has the character of lithology and thicknessChange quickly in transverse direction, strong reservoir heterogeneity, pore type is contend of remaining intergranular pore and intragranular dissolved pore, low porosity and permeability. The prediction of quality reservoir by using logging data and seismic data is very difficulty,because if the feature of reservoir.Basing on the geological features of reservoir, we using varietyseismic techniques and methods to do some analysis and research. First, by using Geological logging, core observation, thin section analysis of information, we determinate the response parameters of sensitive factor in conventional logging, that is resistivity. After the reservoir characteristics has been determined, we selected seismic facies, seismic multi-attribute analysis, geostatistical resistivity inversion and Multi-attribute fusion means to forecast the high quality reservoirs in Baikouquan conglomerate.In the last we using the fusion technology of seismic facies and geostatistical simulation of resistivity and impedance to predict the areadistribution of good reservoir. and also the areadistribution of three reservoirs and shale.According to the research, a series of effective technical means for good reservoirprediction for Baikouquan conglomerate in this area. The result provide reliable and important evidence for controlled reserves calculation and reservoir description in Mabei slope.
