摘要

摘要: 封存箱在沉积盆地中是一种重要而普遍的地质结构,其基本特征为在三维空间具有对流体及能量的屏障,并具相对的封隔性,只在适当的条件下才与外界有物质和能量的交换。它常常是大中型油气田形成和保存的重要地质实体。自然界存在着各种类型的封存箱,有异常高压、异常低压的类型,也有正常压力的封存箱,而后一种类型常常被忽视。封存箱内是否含有烃灶是非常重要的分类标志,含有烃灶的是自源型封存箱,不含烃灶的是他源型封存箱。大中型油气田大多分布在自源封存箱内和临近其顶板或侧板的部位。

Abstract: Compartment is an important and universal structure in sediment basin,and its basic character is provided with barriers or seals for liquid and energy in three dimensions space.It has relative separability,and its liquid and energy could exchange with environment under relevant condition.It always is important geology entity forming and preserving of giant and middle sized oil-gas field.Not only overpressure and underpressure but also normalpressure compartment exist in nature,but the later often was overlooked.The giant and middle sized oil-gas field distributes mostly inside compartment containing hydrocarbon kitchen or near top and side seal of this kind of compartment.Study of compartment regard as one key of exploration decision-making process and the probability of discovery of giant and middle sized oil-gas field.
