摘要:
辫状河砂体是重要的油气储集层,研究其内部结构特征对油气勘探具有重要的指导作用。通过准噶尔盆地南缘托斯台沟辫状河露头实测、岩石相分析以及建筑结构要素精细解剖,总结出6种岩石相,划分出5级层级界面,识别出稳定水流河道、高流态河道、砂坝、废弃河道充填和泛滥平原5种4级建筑结构单元,分别以St—Spx—Sp—Sr,St—St—St,St—Spx—St—Sr,St—Sr—Fl和Sr—Fl—M岩石相组合为特征,并根据各级结构单元和层级界面特征,识别出泛滥平原泥、河道间泥、砂坝内部泥和交错层理层面泥4类泥质夹层。研究表明,目的层段为典型的砂质辫状河沉积,表现为下粗上细、水体能量逐渐减弱的多期、多旋回特征;辫状河砂体中,槽状交错层理砂岩相和板状交错层理砂岩相最为稳定,是构成优势储集单元的基本要素,其中高流态河道和砂坝是有利的储集结构单元,这两类结构单元形成的河道砂体厚度大、侧向连续性好、非均质性较弱,利于油气聚集成藏,是辫状河最为有利的储集层段。
Abstract:
The braided river sand body is a kind of important oil and gas reservoir and its internal structural features have guiding effects on oil and gas exploration. Based on the braided river outcrop survey, lithofacies analysis and architectural element analysis of the Tuositai gully in the southern margin of Junggar basin, 6 types of lithofacies are summarized,and 5 levels of bounding interfaces are divided,and 5 types of 4-level architectural structural units are identified including stable flow channel, high flow regime channel, sand bar, abandoned channel filling and floodplain, which are characterized by the lithofacies assemblages of St-Spx-Sp-Sr, St-St-St, St-Spx-St-Sr, St-Sr-Fl and Sr-Fl-M, respectively. According to the characteristics of each structural unit and its bounding surface, 4 types of muddy interlayer such as mud in floodplain, interchannel mud, mud within sand bar and mud in cross-bedding layer are identified. The study results show that the target stratum is a typical sandy braided river deposit characterized by multiple periods and cycles with coarse grain in the lower and fine grain in the upper and gradually decreased flow energy. In the braided river sand body, the St and Sp lithofacies are the most stable, which are the basic elements of dominant reservoir units. The high flow channel and sand bar are favorable reservoir structural units. The sand bodies formed by these two types of structural units are featured with large thickness, good lateral continuity and weak heterogeneity, which are conducive to oil and gas accumulation and can be the most favorable intervals in braided river reservoirs
