应用分形理论评价齐家古潜山裂缝性油气藏的油气富集性

Assessing hydrocarbon accumulation of fractured reservoir in Qijia buried hill by fractal theory

应用分形理论对欢喜岭油田齐家古潜山圈闭裂缝发育程度进行研究 ,以确定有利的油气聚集区。研究结果认为 :2号和 3号圈闭裂缝最发育 ,是齐家古潜山的最有利油气聚集区 ;应用分形理论对裂缝性潜山油藏各圈闭的裂缝发育程度可以进行定量评价。

Fracture development in Qijia buried hill trap of Huanxiling oilfield has been studied by using fractal theory to find favorable oil and gas accumulation. The result of research is that fractures are most developed in trap 2 and 3, where the most favorable hydrocarbon accumulations in Qijia buried hill are located; fractal theory can quantitatively assess the degree of fracture development in fractured buried hill reservoir.
