油田水:从广义上理解,油田水是指油田区域(含油构造)内的地下水,包括油层水 和非油层水。狭义的油田水是指油田范围内直接与油层连通的地下水,即油层水

一、基本概念 1．均匀应变与非均匀应变；2．蠕变与松驰；3．压溶作用；4．晶质塑性；5．叠加褶皱；6．断层擦痕的倾伏与侧伏；7．深成侵入岩体形成的底辟作用与气球膨胀作用；8．岩石再造作用

一、油气聚集带 含油气盆地是地壳中油气生成、运移、聚集的最基本单元,而背斜、断层等构造是 油气聚集的最小单元,在沉积盆地中,这些构造往往是成群成带出现的。 油气聚集带:在沉积盆地中,受同一个二级构造带所控制或有成因联系、油气聚集 条件相似的一系列油气田的总和,称为油气聚集带。常常用聚集带表示构造型的油气 聚集,用油气趋向带表示地层型油气聚集

一、石油的概念 石油(又称原油)-crude oil:一种存在于地下岩石孔隙介质中的由各种碳氢 化合物与杂质组成的,呈液态和稠态的油脂状天然可燃有机矿产。 组成石油的成分非常复杂,根据其不同的特性,可分为元素组成、馏分组成、组 分组成和化合物组成,三者有相互关系;依据石油中各种结构类型化合物的含量,可对石 油进行分类;不同环境下生成的石油,比如海陆相石油的特征有明显的区别;石油没有固 定的成分,因此石油没有确定的物理参数,石油的物理性质取决于它的化学组成

油气二次运移的结果有两种情况,一种是如果运移过程中无盖层阻挡,油气将一 直向上倾方向运移,直至散失到地表;另一种是运移过程中遇到合适的圈闭,油气将 停止运移,在圈闭中聚集起来。 油气聚集:就是指油气在储层中由高势区向低势区运移的过程中遇到圈闭时,进入 其中的油气就不能继续运移,而聚集起来形成油气藏的过程

Department of Earth and Space Sciences, University of California, Los Angeles The unifying theme in this section is the remarkable weakness of major faults. I will consider the diverse new evidence for weakness, and the evidence for high pore pressure localized in faults as a fundamental cause. With this background one can better understand why faults remain active even after large rotations with

Recognition of fault bend fold, detachment and decapitation has been possible despite the poor quality of the seismic. That was successful because of: A full integration of all disciplines including reservoir engineering petrophysics and geochemistry Vizualization in 3-D that made all members of the team speak the same language

1、节理的定义 节理(joint)即岩石中的裂隙(fissure or fracture),是指没有明显位移的断裂。断裂包含节 理(无显著位移者)和断层(fault)(有显著位移者

STRIKE - The direction of the line formed by the intersection of a horizontal plane with a bedding or fault plane. DIP - The angle formed by the intersection of a bedding or fault plane and the horizontal plane. The angle is measured in a vertical plane perpendicular to the strike

We will now approach the function A(a) from an entirely different point of view, i.e.,we will interpret the S-fabric in terms of strain1. (1.) We assume that the initial fabric is defined by a random orientation of surface, i.e.,that the ODF of the surface is uniform;
