摘要: 综合利用钻井、地震、岩心及区域地质资料,对渤中西环BZ3区的古沟谷和坡折带类型及特征进行了详细的研究,重点分析了不同坡折带类型在基准面旋回变化中对沉积体系的控制作用,并对有利的储集相带和区带进行了初步预测。研究表明,BZ3区存在U、V、W三种类型的沟谷和高位、低位、挠曲3种类型的坡折带,发育于Ⅰ台阶上的三角洲前缘相和Ⅱ台阶上的低位域扇体,是BZ3区储层发育的有利区带。Abstract: Based on the data of well logs,seismics,core and regional geology,the types and characteristics of valley-slope in the BZ3 area were studied in detail,with focus on analyzing the control effect of different type of slope-break zone over the depositional system under the base-level cycles.The favorable areas for hydrocarbon exploration were also predicted primarily in this paper.The results show that there are three types of valleys,i.e.U-shape,V-shape and W-shape valleys,and three slope-break zones,i.e.high,low and flexure ones in the BZ3 area.The delta-front facies developed on the terrace Ⅰ and the low-stand fan developed on the terrace Ⅱ are the favorable areas for reservoir development.
