摘要
流体包裹体是盆地流体的原始样品 ,它记录了地质历史中盆地流体的很多信息。通过研究流体包裹体可以得出其成藏环境的原始古压力 ,这在石油地质领域中具有重要的意义。文章以东营凹陷为例利用流体包裹体分析了其古压力。结果表明 ,东营凹陷在包裹体被捕获时就具有了异常高压 ,以后随着埋藏作用和油气充注的进行 ,异常压力值也在增大 ,从而表明利用流体包裹体研究沉积盆地古压力是一种行之有效的方法 ,能够为古压力的研究提供可靠的依据。
The fluid inclusion is the ancient samples of the basin liquids. It records much information on the basin fluids of the geological history. The paleopressure of the sedimentary environment can be acquired through the study on fluid inclusion, which can supply important information in the field of petroleum geology. This article cites Dongying Sag to analyze its paleopressure by using fluid inclusion. It is concluded that high pressure existed in Dongying Sag when fluid inclusion is captured, and the pressure increases gradually with the geological evolution and hydrocarbon entrapment of the sag. It can be seen that fluid inclusion is an effective means in studying paleopressure, and it can supply reliable basis for the study of paleopressure.
