根据平湖油气田勘探开发现状,分析研究了平湖油气田油气地质特征和油气富集规律,论述油气勘探潜力,指出平湖油气田勘探潜力既有未钻探的构造圈闭,也有隐蔽型圈闭。根据平湖油气田油气储量不足,亟待扩大后备储量的现实问题,提出了"坚持勘探开发一体化,加强油气地质综合研究,引进新技术新方法,全面评价,降低风险,扩大后备储量"的勘探指导思想和目标,具体制定了"构造圈闭勘探主探中带,兼顾西带和东带:积极探索,加大隐蔽圈闭勘探力度"的勘探部署。

Based on current exploration of Pinghu Oilfield, the hydrocarbon geological characteristics and accumulation law of this oilfield are analyzed, and its hydrocarbon potential is illustrated that undrilled structural and subtle traps are the best potential areas. Reserves of Pinghu Oilfield is not enough and it's urgent to increase its candidate reserves, so this paper proposes guiding exploration theory and goals which are: stick to the integration of exploration and development, strengthen study of hydrocarbon geology, introduce new technology, do overall evaluation, reduce risks and increase candidate reserves. Specified ex-ploration planning is also made: explore mainly the middle part of structural traps and meanwhile pay attention to the west and east parts, and strengthen the exploration of subtle traps.
