双河油田是我国典型的"小而肥"油田,储量丰度300.4×10~4t/km~2.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.
雙河油田是我國典型的"小而肥"油田,儲量豐度300.4×10~4t/km~2.但分析髮現,在儲量豐度如此之大的油田,大部分圈閉併未充滿油氣,而且不同圈閉的充滿度有較大的差異.研究錶明,這種差異與儲層滲透率級差優勢通道有較大的關繫,即儲層通道滲流能力對油氣充註起控製作用,油氣充註受到油組內級差優勢的控製.

Shuanghe Oilfield is a typical "small and fat" oil field with great oil abundance in China. However, as a big oil field, it was found that mostly traps have not been filled with oil and gas. Further more, oil-gas filling degrees of different traps show great differences in the oil field. The result of research shows that the difference has great relationship between reservoir permeability grade differential and dominant channel, that is, the process of the oil and gas filling is controlled by channel seepage flow capacity and the oil group' s grade difference of reservoir.
