摘要:
基于区域地质背景资料,综合运用岩芯观察、岩相和测井相分析等手段,对临南油田街2断块沙三上亚段Ⅴ砂岩组沉积微相的沉积相标志、类型以及展布特征进行了系统研究。结果表明:临南油田街2断块沙三上亚段Ⅴ砂岩组为一套湖泊三角洲沉积体系,亚相类型为三角洲前缘亚相;沙三上亚段Ⅴ砂岩组主要沉积微相可细分为水下分流河道、水下分流河道间湾、河口坝、远砂坝和前缘席状砂等5种微相,并建立了沉积微相识别模式;沉积特征和沉积微相的平面展布呈现在近东西向剖面上砂体连续性较好,可见河口坝与前缘席状砂的交替出现,而在近西南—北东向剖面上,砂体横向上一般由水下分流河道过渡到河口坝或前缘席状砂。总之,临南油田街2断块沙三上亚段Ⅴ砂岩组是研究区三角洲形成的高峰期,水下分流河道、河口坝、前缘席状砂为主要的储集砂体。
Abstract:
Based on the regional geological data, the distribution characteristics, index and type of sedimentary microfacies of the sand groupⅤof the upper Sha-3 Member in Jie Faulted Block 2 of Linnan Oilfield were studied systematically by means of core observation, lithofacies and log facies analysis. The results showed that the sand groupⅤof the upper Sha-3 Member in Jie Faulted Block 2 of Linnan Oilfield was a lake delta sedimentary system, parfacies type was delta front; the sedimentary microfacies of the sand groupⅤwas divided into underwater distributary channel, underwater interdistributary bay, mouth bar, distal bar and front sheet sand, and the corresponding recognition modes were built; characteristics and plane distribution of sedimentary microfacies were that the continuity of sand body was fine in east-western profile, mouth bar and front sheet sand were alternate, and sand body horizontally transited from underwater distributary channel to mouth bar or front sheet sand in southeast-northwestern profile. In general, the sand groupⅤwas at the peak of forming delta, and underwater distributary channel, mouth bar and front sand sheet were the favorable reservoir sand bodies.
