渤海湾盆地冀中坳陷和二连盆地岩性地层油气藏研究和勘探实践发现,富油凹陷油气分布具有“互补性”特征,既构造和岩性地层油气藏在油气资源分配、空间分布上具有“互补性”,这种分布特征是由构造与岩性地层油气藏所赋存的宏观地质背景、成藏条件、成藏机理等多种因素的耦合所决定的。进一步研究表明,油气分布的“互补性”在各类陆相盆地中具有普遍性。这一“规律”的揭示,有助于在油气勘探实践中树立新的勘探理念,建立科学的勘探程序,制定正确的勘探部署。对推进我国陆相含油气盆地油气勘探工作向纵深发展具有重要意义。 The research and exploration of lithologic reservoirs in Jizhong depression and Erlian basin of Bohai Bay basin found that the distribution of oil and gas in the oil-rich sags is characterized by “complementarity”. Both the structural and lithologic reservoirs have great potential in oil and gas resource allocation and spatial distribution Is characterized by the “complementarity”, which is determined by the coupling of structural and lithologic stratigraphic macroscopic geological backgrounds, reservoir forming conditions and hydrocarbon accumulation mechanisms. Further research shows that the “complementarity” of oil and gas distribution is universal in various continental basins. The revelation of this “law” helps to establish a new exploration concept in oil and gas exploration, establish a scientific exploration program and formulate the correct exploration and deployment. It is of great significance to promote the deep-seated development of oil and gas exploration in continental oil-gas basins.
