摘　　要：莫深1井是中国石油在准噶尔盆地腹部部署的一口重点科学探井,完钻井深7500m.该井钻探层位深、地层变化大,其钻井完井的顺利实施对认识莫索湾地区深层压力分布有重要作用。分析了莫深1井区域地层压力的纵、横向特征,并在该区三维地震资料测井约束反演的基础上,获得了该区域三维层速度体,进而运用Bowers方法计算出该区三维地层压力。有效提取了该区2口重点探井莫深1及盆参2井位置上的地震层速度,分别与其测井声波速度进行了比较,结果吻合较好,表明此三维压力能较好地反映该地区压力分布。Moshen-1 Well is a key well for scientific probe of CNPC, with completion depth of 7 500 m. This well is characterized by deep drilling horizon and varied formation lithology, so its successful drilling and completion played an important role to understand deep pressure distribution in Mosuowan area. This paper presents the characteristics of vertical and transverse formation pressure in Wellblock Moshen-l, and based on 3D seismic data constrained inversion by well logging, obtains 3D interval velocity. Finally, by taking advantage of Bowers method, 3D pressure in this area is gained. The correlation of seismic interval velocity from Moshen-I Well and Pencan-2 Well with sonic logging velocity is made, and the more consistent results show that the 3D pressure can well reflect the pressure distribution in this area.
