【摘要】 于奇-草湖地区是塔里木盆地塔河油田外围重要的油气勘探地区。依据各种地震反射标志,利用地震反射波的振幅、连续性、内部结构和外部形态等地震反射特征,总结划分出叠瓦型前积地震相、丘状地震相、河道充填地震相、杂乱地震相、空白地震相和席状地震相等6种地震相类型,对不同地震相所指示的沉积相做出了合理的解释。更多还原

【Abstract】 Yuqi-Caohu block is an important area of oil and gas exploration in the north of Tahe oilfield in Tarim Basin.According to a variety of seismic reflection,in the use of seismic reflection characteristics,such as amplitude,continuity,internal structure and external shape of reflected waves,summarized six kinds of seismic phases types,such as imbricated foreset seismic phase,mounded seismic phase,channel fill seismic phase,chaotic seismic phase,blank space seismic phase and sheet seismic phase,and make reasonable explanation of each seismic phase directed to sedimentary phase.更多还原
