从典型实例感悟油气勘探

Implications from typical petroleum exploration cases

2005年以来,面对勘探程度不断提高、勘探难度不断加大的现实,中国石油天然气股份有限公司大力实施资源战略,油气勘探获得了一批重大突破与发现,呈现油气并举、新老区比翼齐飞、储量单体规模大等特点,迎来了新的储量增长高峰期,连续6年探明石油地质储量超7×108t,连续6年探明天然气地质储量超4 000×108 m3,成为中国油气勘探史上成果最丰、探明储量最多、储量高峰期持续时间最长的时期之一。通过典型勘探实例总结分析,提出了5点感悟和体会:油气藏在勘探家的脑子里是找油的哲学基础;大油气区理论是推动油气勘探持续发展的重要指导;解放思想、重新认识是成熟探区勘探突破发现的必由之路;勇于探索是实现新区勘探突破的关键;攻克瓶颈技术是实现战略突破的重要保障。

Since 2005 PetroChina has faced with incessantly higher exploration extent and more exploration difficulties, however, with vigorous implementation of the resource strategy, it has achieved a series of significant breakthrough and discoveries in oil-gas explora- tion, which are characterized by ＂simultaneous exploration of oil-gas resources＂, ＂emphasis on both new and old areas＂ and ＂large re- serves in a single reservoir＂. With the proven oil and gas in geological reserves exceeding 7 x 10s t and 4 000 x 10Sm3 , respectively, for seven or six consecutive years, PetroChina is embracing a new round of the reserves growth peak, one of the best periods during which China has the most exploration achievements, largest proven reserves and longest reserves peak. Based on the analysis of typical explo- ration examples in China, we summarized 5 aspects of understanding on and inspiration from the past exploration practice, i.e. the basic philosophy of oil exploration is ＂to have oil-gas reservoirs always in the mind＂, the theoretical knowledge of giant oibgas provinces is impor- tant guidance for continuously pushing petroleum exploration forward, to liberate our minds and restudy the highly-explored areas are the in- evitable course to achieve an exploration breakthrough in these areas, exploring without fear is the key for an exploration breakthrough in new areas, and to make a breakthrough in bottleneck technologies largely guarantees strategic advances in petroleum exploration.
