辽河坳陷中浅层精细勘探做法与启示
|
摘要
辽河油田已经进入高成熟勘探阶段,需深入开展中浅层精细勘探工作,以提高勘探效益。近年来,针对辽河坳陷中浅层勘探程度高,小断块、薄砂层、复杂油藏发育的特点,通过开展区带优选、创新地质认识、精细目标刻画,由大层构造解释向层间微幅度构造精细刻画转变,由叠后地震反演向叠前/叠后地震联合反演延伸,多学科联合攻关挖掘勘探潜力,勘探开发一体化快速建产等方面的工作,实现了老区周边、老区新层系勘探新发现,发现了多个千万吨级优质储量区块。勘探实践表明,提高中浅层优质储量发现程度是效益勘探的重要途径。
After entering highly mature exploration, the Liaohe oilfield should be finely explored in the middle and shallow reservoirs to improve exploration efficiency. In recent years, to adapt the conditions such as highly explored middle and shallow reservoirs, small fault blocks, thin sandstone layers and complex reservoir development in the Liaohe depression, a series of work have been carried out, involving selection of good zones, innovation of geological understanding, fine target characterization, fine interpretation of micro-relief structures instead of massive structures, combined pre-stack and post-stack seismic inversion instead of post-stack seismic inversion, multi-disciplinary research on exploration potentials, rapid production capacity construction through integrated exploration and development. The implementation of the measures above made new discoveries of several high-quality reservoirs with reserves at 10 million-ton scale in the surroundings and new formations of old fields. Exploration practice shows that to make more discoveries in the middle and shallow reservoirs is important for efficient exploration.
