摘要:

以东营凹陷西部的金8—滨188剖面为研究对象,应用过程约束的盆地模拟方法恢复关键成藏期油气成藏动力演化史。通过建立储层物性恢复图版的方法恢复储层古物性,进而求得储层关键成藏期的毛细管阻力并恢复了以其作为成藏阻力的演化史;通过油气成藏动力与阻力进行耦合,获取了成藏动力梯度的演化史;利用成藏动力梯度演化史和已发现油气藏的关系预测有利成藏区带。金8—滨188剖面缓坡带的滩坝砂成藏条件最好,为Ⅰ类有利部位,坡底浊积岩透镜体和缓坡带的三角洲为Ⅱ类有利部位,坡底的滩坝砂为Ⅲ类有利部位。

Abstract:

Taking the Jin 8-Bin 188 section in the west of Dongying sag as an example, this research rebuilt the evolution of driving force for hydrocarbon accumulation by basin modeling  with the constrained procedure. The porosity and permeability of reservoir were recovered with charts of porosity evolution. The capillary force of reservoir was calculated, and the evolution of driving force for hydrocarbon accumulation was recovered when the capillary force was taken as the resistance force, and the evolution of the dynamic gradient for hydrocarbon accumulation was also simulated by coupling the driving force and resistance force. After the comprehensive analysis of the relationship between the evolution of dynamic gradient and the discovered hydrocarbons, this research predicted the favorable oil and gas accumulation zones. In the Jin 8-Bin 188 section, the damandbeach sands are the first-class favorable zone for the reason that the sands have the best condition for hydrocarbon accumulation; the turbidite fan lens at the slope and the delta sands at the gentle slope are the second-class favorable zone; the damandbeach sands at the bottom of slope are the third-class favorable zone.

Key words: Dongying sag;hydrocarbon accumulation process;dynamic gradient, resistance;driving force
