阜东斜坡-北三台地区成藏动力学系统研究

THE EAST OF FUKANG SLOP-NORTH SANTAI AREA HYDROCARBON-ACCUMULATING DYNAMIC SYSTEM RESEARCH

成藏动力学系统是在含油气系统理论的基础上,针对油气流体矿产的特点而提出来的.含油气盆地实质上不仅是一个"低温热化学反应器",更是一个复杂的流体(油气水)渗流的成藏动力系统.油气从源岩到圈闭的作用机制和过程非常复杂,通过探讨油气成藏各个环节,指出影响油气赋存的因素,可以指导油气勘探工作.基于成藏动力学系统理论,将阜东斜坡-北三台地区划分为8个成藏动力学系统,建立了6个成藏动力学模式,提出2个勘探导向目标:①在勘探程度较低的白垩系寻找它源多向充足的油气藏类型;②在斜坡区寻找以三叠系小泉沟群为源岩所形成的自源封闭型高压油气藏.

hydrocarbon-accumulating dynamic system is developing at oil system theory ,petroliferous basin in fact is not only a low temperature heat chemistry reactor ,but also is a complicate fluid （oil and water ） flow through porous medium hydrocarbon-accumulating dynamic system, oil and gas formation from mother rock to closure is very complicate, and research every parts of oil and gas hydrocarbon-accumulating in basin .Hunting the field＇s probably position, then guide the exploration activity .author use hydrocarbon-accumulating dynamic system theory, The east of FuKang slop divide into eight parts of hydrocarbon-accumulating dynamic system ,build six hydrocarbon-accumulating dynamic modes,hunting two explore attack： 1 .hunting the other source abundant reservoir modes at the low degree of exploration ;2. the mother rock with the Triassic system Xiaoqungou group neogenic self-source closed high pressure reservoir.
