异常压力，无论是低压力还是高压力，在世界各地的许多盆地中都很常见。如果要安全钻井，就需要清楚地了解这些压力状态。该规划的先决条件之一是预测储层以及页岩和其他低渗透岩性中的孔隙流体压力。为此，本专题集中体现的最新进展见证了地质衍生压力模型的发展，其基础是对导致异常压力的多种机制的理解。这些认识使得在更复杂的岩性体系中可以更准确地解释孔隙流体压力，例如碳酸盐岩/碎屑岩系统和通常包含高度超压盐内储层的盐主导系统。此外，这些模型现在被用来通过改进速度预测来改进盐下孔隙压力预测并识别为流体提供横向运移路径的水动力含水层，从而推动新的勘探工作。
Abnormal pressure, either low or high, is commonly found in many basins around the world. A clear understanding of these pressure regimes is needed if wells are to be drilled safely. One of the prerequisites for this planning is prediction of pore fluid pressure, in both reservoirs and also in shales and other low-permeability lithologies. To this end, recent advances, captured in this thematic set, have seen the development of geologically derived pressure models, underpinned by an understanding of the multiple mechanisms that cause abnormal pressures. These understandings lead to more accurate pore fluid pressure interpretation in more complex lithological regimes such as carbonate/clastic systems and salt-dominated systems that often contain highly overpressured intra-salt reservoirs. Further, these models are now being used to drive new exploration plays by improving velocity predictions to improve sub-salt pore pressure predictions and identifying hydrodynamic aquifers that provide lateral migration paths for fluids.
