双河油田是我国典型的“小而肥”油田,储量丰度300.4×104t/km2。但分析发现,在储量丰度如此之大的油田,大部分圈闭并未充满油气,而且不同圈闭的充满度有较大的差异。研究表明,这种差异与储层渗透率级差优势通道有较大的关系,即储层通道渗流能力对油气充注起控制作用,油气充注受到油组内级差优势的控制。 Shuanghe Oilfield is a typical “small and fat” oilfield in China with a reserve abundance of 300.4 × 104t / km2. However, the analysis shows that in the oilfields with such rich reserves, most traps are not full of oil and gas, and the degree of fullness of different traps is quite different. The study shows that this difference has a great relationship with the channel of differential permeability of reservoir permeability, that is, the reservoir channel seepage ability plays a controlling role in the filling of oil and gas, and the filling of oil and gas is controlled by the advantage of internal differential in oil group.
