Identification of sand body based on seismic high resolution 3D nonlinear inversion in Moxizhuang, Junggar Basin, China
摘要
Abstract
The sandstone reservoir of Jurassic Sangonghe Formation at Moxizhuang area in Junggar Basin is controlled by lithology and structures,and characterized by inhomogeneous physical conditions caused by superimposition of multiphase channel sand body,the vertical and horizontal variation and the ambiguous distribution of sand bodies.Based on 3D seismic data,such as well drilling,logging and oil testing,a lot of parameters,including velocity,density,and gamma reflecting distribution features of sandstone are obtained by inversion and processing with high resolution nonlinear 3D inversion method.These data are integrated with other geological data to analyze the deposition,grand total thickness of sandstone,effective total thickness of sandstone and distribution of reservoir.The identification and evaluation standard of sandbody of Sangonghe Formation is established on the basis of characteristic analysis of physical property.The characteristics of spatial distribution of sand body and effective sand body of the Sangonghe Formation are obtained according to lithological classification standard and seismic multi-attribute data.It reveals that the sand body and effective sand body of the Sangonghe Formation occur as stripe,sand bar and sheet-like sand parallel to the regional deposition direction.The sand bodies in the J1s12 and J1s22 Sections of Sangonghe Formation have relatively large thickness,and therefore,bear favorable physical property,high capacity of oil and gas and good prospect for exploration and development of natural resources.关键词
