摘要
舍女寺油田含油层系多,先后发现了6套含油气层系,但因为成藏条件复杂,油气分布规律不明确,给开发带来了不少苦难。本次工作对油气的分布规律进行深入研究,发现油气藏主要分布在大断层两侧的反向断鼻或断块圈闭内,分布规律主要受烃源岩分布、盖层分布以及断层系统的控制,储量丰度受沉积相的影响,这就为下步滚动勘探开发提供了方向。
Shenusi oilfield has many oil-bearing systems.6 sets of oil-bearing systems have been successively discovered in the oilfield,but the reservoir forming conditions are complicated and oil and gas distribution is uncertain,thus bringing many difficulties to development.The distribution of oil and gas is studied and it is discovered that reservoirs mainly distribute in antithetic nose or fault-block traps on both sides of the big fault.The distribution was controlled by source rock distribution,caprock distribution and fault system.Reserve abundance was subjected to sedimentary facies.This study gives a direction for next step exploration and development.
