Cretaceous shales in the Laramide basins of Wyrning typically are anomalously pressured. The top of the anomalously pressured transition zone is identified by marked increases in sonic transit time, hydrocarbon production index (PI), clay diagenesis,and vitrinite reflectance. The affected shales are characterized by bitumen-filled microfractures. The overpressured Cretaceous shale section in a Laramide basin is a basinwide, dynamic pressure compartment. The driving mechanism of pressure compartmentalization is the generation and storage of liquid hydrocarbons that subsequently partially react to gas, converting the fluid-flow system to a multiphase regime in which carpillarity controls permeability, the result is elevated displacement pressures within the shales. In contrast,the Cretaceous sandstones within a basin are subdivided stratigraphically and diagenetically into relatively small,isolated pressure or fluid-flow compartments within the shale section- These stratigraphic elements are low-permeability rocks with finite leak rates in a single-phase fluid-flow system; they evolve diagenetically during progressiveburial, and become impermeable capillary seals with discrete displacement pressures as the flow regime evolves into a multiphase fluid-flow system by the addition of hydrocarbons. The saturation of these compartments with liquid hydrocarbons and the subsequent oil-to-gas reaction causes the expulsion of free water, resulting in a gas accumulation without gas-water interface. In the Laramide basins of Wyoming, the major difference between pressure compartmentalization in Cretaceoes sandstones and shales is one of scale. In both cases,the appearance of hydrocarbons drives the transition from a single-phase(H2O) to a multiphase fluid-flow system. The hydrocarbons activate capillary seals; as the oil - gas reaction proceeds, the sandstone/shale system becomes saturated with hydrocarbons, greatly increasing displacement pressures in the fluid-flow barriers. If three-dimensional closure of the low permeability elements occurs, then fluid compartmentalization occurs. When hydrocarbons saturate the compartment, the integrity of the three-dimensional boundary capillary seals is established,resulting in an anomalously pressured gas accumulation.

在怀俄明州Laramide类盆地白里系页岩中,普遍存在高压。高压地层顶部的过渡带可以用声波过渡时间、碳氢化合物指数(PI)、伊利石化程度、干酪根的结构以及镜质体反射率的变化加以确定。白垩系页岩形成的圈闭是一个区域性连续分布的压力圈闭,高压的来源主要是石油的生成及石油向天然气的裂解。石油及天然气的演化过程导致流体流动系统从单相(以水为主)转化为多相(油、气、水),相对渗透率及毛管压力成为控制封闭层渗透率及封闭能力的主要因素。与区域性的高压页岩圈闭相比,砂岩由于相变或成岩作用而形成相对较小而且互相分隔的异常压力圈闭。这种砂岩圈闭在初始时,随着埋深的加大,石油天然气含量增加,一些渗透地层演变成为相对不渗透的毛管压力封闭。随着石油的进一步聚积及油气的转化,使砂岩中的自由水逐渐被驱除,因此这种异常压力气田是不存在气水界面的。以油气生成为驱动力的异常压力圈闭不同于以水为驱动力(不均衡压实)的异常压力圈闭。前者和油气生成、运移及聚积有关,可以在地质历史时期中长期存在,可以出现在任何年代的地层中,可以在很大的深度范围内出现。所以,对成因上与油气生成、运移、积聚密切相关的异常压力圈闭的理解、对深部盆地天然气资源的勘探、开发都有...
