摘要
Abstract
In view of the characteristics of small sandstone mass,multi-stage sand superposition,difficult division of sedimentary stages,strong heterogeneity,the sweet spot area in Heilongmiao region,Nanyang Sag is difficult to predict.Therefore,the visualization technology is used to analyze the fine structure of the 3D seismic data and restore the paleo-structure,and then the study on the genesis of the sand gravel rock mass is carried out.According to the sedimentary cycle and seismic reflection structure of sand-sand body,the sedimentary stages of sand-gravel rock mass are divided on the basis of sequence stratigraphic division of 5 wells.Through petrol-physical analysis and forward modeling,the geophysical response characteristics of gravel rock mass are determined.Through the correlation analysis between the seismic reflection charac-teristics of fan root,fan middle and fan end at well point and the seismic reflection characteristics of other points in the same layer,the plane distribution is determined.Through the intersection analysis of the meas-ured lithology,physical property parameters and wave impedance properties,the range of wave impedance properties of gravel rock and mudstone is determined.Based on the wave impedance data obtained by high-precision inversion,the effective reservoir thickness and distribution are obtained under the control of the wave impedance range and the top and bottom reflection horizon,and the sweet spot area of the sandstone reservoir is delineated.Based on this,the HL1 well deployed in the sweet spot produced 5.46 m3/d,which is consistent with the actual drilling results.关键词
