()、段砂体主要经历压实、胶结、须家河组T溶蚀、交代及破裂等成岩作用,可进一步分为以xx2T33
压实和石英次生加大为主、以绿泥石环边为主和以早期方解石胶结为主的3种成岩演化路径.
()沉积作用是储层砂体物性的先天因素,压实作用是储层致密的主要原因,成岩作用过程中的石英3
次生加大造成储层质量的致命性破坏,溶蚀程度低是储层砂岩致密的另一个重要原因.()储层致密化时间发生在烃类充注前,石英次生加大边中发育的盐水包裹体均一温度集中分布在4
推算致密化深度介于1表明致密化过程发生在燕山构造活动期间,00~120℃之间,25~2864m之间,17
8
储层致密的时间应在1.a左右.5×10
()致密化过程划分为准同生期—早成岩A期的原生孔隙的迅速破坏阶段、早成岩A期—早成岩B5
期的机械压实阶段、早成岩B期—中成岩A期的胶结等3个阶段.
