以松辽盆地南部岩性地层油气藏成功勘探为例,系统阐述了层序地层理论对岩性地层油气藏勘探所起的指导作用,区域层序地层研究指明岩性地层油气藏勘探方向,高分辨率层序地层研究提供勘探井位。同时,针对三角洲前缘带岩性地层油气藏具砂泥岩薄互层、断裂系统复杂、低孔低渗储层导致油层电阻率低和产能低等特点,系统陈述了先进实用的勘探技术在岩性地层油气藏勘探中所发挥的重要作用。最后,对岩性地层油气藏的勘探步骤和各步骤所对应的研究成果、图件和技术保障进行了系统的总结。

Theories and Practice for Exploration of Lithologic Stratigraphic Oil and Gas Reservoirs in Southern Part of Songliao Basin

With the successful cases in exploration of lithologic stratigraphic oil and gas reservoirs in the southern part of Songliao Basin, this article systematically elaborates on the guiding role that the sequence stratigraphic theory plays in exploration of lithologic stratigraphic oil and gas reservoirs. The regional sequence stratigraphic study clari?es the orientations for exploration of lithologic stratigraphic oil and gas reservoirs while the high-resolution sequence stratigraphic study provide the position of exploration well. Meanwhile, this article systematically describes how the advanced and applicable exploration technologies play an important role in exploration of lithologic stratigraphic oil and gas reservoirs in the light of the characteristics of such reservoirs, such as thin sandstone-shale interbeds, complicated fault systems, low resistivity and low production of oil layers caused by low porosity and low permeability. Finally, the article systematically summarizes the steps for exploration of lithologic stratigraphic oil and gas reservoirs as well as the related research results, ?gures, and technological supports.
