摘要
台北凹陷神泉油田侏罗系油藏储量占全油田的70%,是神泉油田的主力油藏,油藏类型为复杂断块油藏。平面上受北东走向断层和东西走向两组断层夹持形成了"墙角式"的16个含油断块,各断块之间无统一油水界面;纵向上发育44个油藏,单个油藏规模小,以低丰度油藏为主。继承性发育的古构造背景控制了油藏的形成与演化,正向构造的周全程度影响了油气的富集程度,断层封闭的相对性和易变性导致油气分布贫富差异更趋明显、油水关系更加复杂化,对这一典型油藏进行分析,明确控油因素,将有助于进一步明确该区滚动勘探的方向,开拓新的找油领域。
The reserves of the Jurassic reservoirs, which are the major complex fault block reservoirs in Shenquan oilfield, account for 70% of the total oilfield. Sixteen 'comer - like' oil - bearing fault blocks have been formed through north by east faults holding with east to west faults, which have no uniform water - oil contact. There developed 44 reservoirs of small scale and low abundance vertically. A setting of inherited structure dominated the formation and evolution of the reservoirs, the sealing degree of the positive structures affected the oil and gas concentration, at the same time, the relativity and variability of fault closure caused more distinctive oil and gas distribution difference and complex water and oil relation. To clarify the oil control factors through analysis of the typical reservoir will be helpful in determining the exploration targets in this area.
