摘要

平湖构造带有正常凝析油、非正常凝析油、轻质原油和正常原油4种类型原油。天然气以热解成因的凝析气为主。平湖构造带产出的油气以凝析气为主

原油次之。花港组油气藏以背斜型油藏为主

并多被断层所切割;平湖组油气藏依附于断裂

多为受同生断层控制的断块和半背斜凝析气藏。

Abstract

There are four oil types in Pinghu structural zone

i.e. normal condensate

abnormal condensate

light crude oil and normal crude oil. Natural gas is mainly of pyrolysis product-condensate gas. Hydrocarbons produced from Pinghu structural zone are mainly of condensate gas

and then to be followed by crude oil. Reservoirs in the Huagang Formation are mainly of anticlinal type

and most of them have been cut by faults. Reservoirs in the Pinghu Formation are mostly fault block and semi-anticlinal condensate gas pools controlled by contemporaneous faults.
