中文摘要	苏里格地区西北部沙漠地表复杂,低孔低渗储层具有岩性变化大、非均质性较强、与围岩波阻抗差异小的特点. 地震储层预测关键不是找砂体,而是寻找砂体中物性相对较好的有效储层. 在高精度全数字地震资料的基础上,以岩石物理分析为前导,以叠前多参数反演及交会为核心技术,并建立岩石物理解释量板,精确刻画盒8段砂体展布形态,圈定有效储层展布; 利用三维可视化技术准确描述目的层的砂体和有效储层展布特征,为水平井地质导向提供依据. 全数字三维采集处理解释一体化应用,实现了储层预测从平面到立体、从垂直到水平的转变,大幅度提高了Ⅰ + Ⅱ类井比例和水平井的储层钻遇率,从而进一步提高了苏里格气田的整体开发效益.
英文摘要	In the northwest of Sulige,the surface of the desert is complicated and the reservoirs with low porosity and low permeability are characterized by large lithological changes and strong heterogeneity, which are different from those of the surrounding rock. The key of seismic reservoir prediction is not to find sand bodies,but to find effective sand bodies with comparatively good physical properties. On the basis of full digital seismic data with high precision,we carry out petrophysical analysis,pre-stack inversion and rendezvous analysis, and establishment of rock physical interpretation template. Then we can accurately depict H8 sand body distribution and delineate effective reservoir distribution. And the sand bodies and effective reservoir distribution characteristics of the target layer are accurately described by 3D visualization technology,which can provide the basis for the geological guidance of horizontal wells. The integration application of full digital 3d acquisition,processing and interpretation,has realized the reservoir prediction transition from plane to solid,from vertical to horizontal, greatly improve the Ⅰ +Ⅱ class well ratio and the reservoir drilling rate of horizontal well, thus furtherly improve the overall development of gas field in a comprehensive benefit.
