塔里木盆地塔北塔中地区寒武系勘探生产实践揭示,油气分布严格受控于断裂,不同断裂段之间油气差异性显著,断裂带具有重要的垂向输导作用。因此,加强塔北塔中地区中、下寒武统的岩性组合与变形特征研究,对判定整体地层变形情况和厘清影响油气输导效率的因素具有重要意义。本研究以塔里木盆地塔北塔中地区中、下寒武统为研究对象,基于岩心、钻/测井、3D地震及生产动态数据等资料,首先开展岩石类型划分和岩性组合分析,然后通过井震标定及区域地震剖面追踪,明确岩性组合的地震响应特征,最后指明断裂作用下目的层变形特征,揭示岩性组合与构造变形特征对油气输导效率的影响。研究结果表明:(1)研究区共发育白云岩类、含膏岩类和含泥白云岩类等3种岩石类型,根据叠置样式分为上下分段型、对称型和互层型三种岩性组合;(2)不同岩性组合的地震反射特征存在显著差异性,上下分段型岩性组合对应于上部弱振幅、下部强振幅,呈现席状平行亚平行反射特征,对称型岩性组合表现为具有中强振幅且连续性较好的地震反射之间夹持着弱振幅、连续性中等的席状平行反射的特征。互层型岩性组合表现为强振幅、高频率和连续性好的地震反射特征;(3)在不同的应力分段作用下,目的层变形特征分为膏岩层厚度减小、厚度增大及厚度稳定共3种类型。研究揭示出岩性组合与构造变形联合控制着油气输导,顺北区块岩性组合的叠置样式呈现明显的区域差异性,西部以对称型叠置为主,东部以上下分段型对称型为主。对称型岩性组合的变形程度较高有利于油气输导,上下分段型岩性组合在拉分段更为有利。

在干旱气候背景下,盆地边缘可形成一种发育于盆地边缘并顺源延伸至湖盆边缘终止的大型沉积体系,即分支河流体系,其主体往往被称为冲积扇。分支河流体系规模较大,沉积过程复杂,其沉积物可形成大规模的油气、水储层。为了明确干旱型分支河流体系沉积演化过程及其不同时期沉积特征的差异,通过水槽沉积实验模拟再现其沉积过程,并采用三维激光扫描、延时拍摄等技术手段精确监测。研究结果表明:1)分支河流体系的半径、边缘糙度与模拟期次(沉积物供给)呈对数相关关系,同时其增生规律呈现明显的阶段性差异,据此可将沉积演化过程划分为早期、中期及后期三个阶段。2)各阶段沉积特征存在较大差异,初期阶段以片流为主,片流单元在分支河流体系表面呈连片状多期次迁移叠置,中期阶段非限制性河道的侧向迁移及与其远端相连的限制性河道的形成与废弃共同主导了沉积过程,后期阶段非限制性河道发育程度大大降低而限制性河道发育程度大大增加并主导沉积过程。3)分支河流体系的三阶段演化导致其本身由三个沉积特征差异较大、空间结构迥异的沉积层构成,包括底层片流朵体复合体、中层非限制性河道与限制性河道切割叠覆体、顶层限制性河道切叠沉积体。

Given any integers a,b,c, and d with a 〉 1, c ≥ 0, b ≥ a＋c, and d ≥ b ＋ c, the notion of （a, b, c, d）-Koszul algebra is introduced, which is another class of standard graded algebras with ＂nonpure＂ resolutions, and includes many Artin-Schelter regular algebras of low global dimension as specific examples. Some basic properties of （a, b, c, d）-Koszul algebras/modules are given, and several criteria for a standard graded algebra to be （a, b, c, d）- Koszul are provided.
