摘要
盆地封隔体即盆地中异常流体压力封隔体，又叫流体封隔体或压力封隔体，它在三维空间上被封隔层所封闭，封隔体的形状各异，规模可大可小，由于封隔层的封闭作用，封隔体中的流体具异常压力，因此封隔体是封闭的水动力系统，其内部相互连通，与外部则是隔绝或有限连通，同时也是油气生，运，聚的单元，研究盆地封隔体对于了解地下流体的运移，油气的聚集，油气资源评价，含油气系统的划分以及油气勘探等具有重大意义。
Basin compartments mean abnormally pressure compartments in the basin. They have also known as fluid compartments or pressure compartments. They are confined by seals in three dimensions and different from each other in shape and volume. Due to the sealing capability of a compartment, the fluid in the compartment has abnormally pressure. Therefore,a pressure compartment is a sealed hydrodynamic system that is connected inside and isolated with outside. In the mean time, a pressure compartment is a unit to generate,transfer and accumulate oil and gas. To study basin compartments is significant for understanding underflow migration,oil and gas accumulation, resource evaluation, division of petroleum systems, and exploration of oil and gas.
