摘要

摘要: 渤海湾盆地沾化凹陷埕南地区沙河街组陡坡扇体发育,但发育规律复杂、地层对比难度大、储层非均质性强,缺乏有效的储层定量评价手段。在明确扇体控砂机制基础上,通过古坡角的定量计算,分析储层的纵横向演化规律。古物源的展布与古地形具有明显的匹配关系;边界断层倾角角度越大,扇根亚相越宽,扇中亚相宽度越窄。砂体展布具有"沟扇对应"、大沟对大扇,物源量供给充足、"连片发育",纵向上"扇体后退"的特点。应用地球物理分析和地质综合统计2种方法,圈定了砂砾岩体有效储层,剔除非有效的致密砾岩。沙三下亚段3砂组在滨古604、义159等井区属于致密扇根相带,具有侧向遮挡的作用;义109、义104-4等井区属于扇中相带即有效储层分布区,具有非油即干的特点,是成藏的有利区;义107-1井区处于扇体的扇端部位,有效储层不发育。

Abstract: Fans are widespread in the Shahejie Formation in the northern steep slope of Chengnan area in the Zhanhua Sag. They are distributed in a complicated pattern. It is difficult to make stratigraphic correlation. Reservoir heterogeneity is strong. As a result, an effective method for the quantitative evaluation of reservoir is demanded. We studied the mechanism of sand-control, and determined the vertical and horizontal evolution rules of reservoirs by the quantitative calculation of slope angle. The distribution of paleo sources matches well with paleotopography. Higher boundary fault angle led to a wider fan root and narrower middle-fan. The distribution of the sand body can be summarized as the matching of the channel and fan, the matching of a large channel and large fan, sufficient supply, continuous development, and vertically backward fan. We found some effective reservoirs by using geophysical and geological statistics. Sand group no. 3 in the lower section of the third member of Shahejie Formation close to wells Binggu604 and Yi159 has a tight fan root, which impedes lateral hydrocarbon migration. Middle fan facies around wells Yi109 and Yi104-4 work as effective reservoirs for either oil or dry gas, and are favorable exploration targets. The area around well Yi107-1 is a fan edge, where few effective reservoirs developed.
