胡庆断裂带由于构造复杂,油气藏类型较多,石油储量探明率仅为37%左右,具有较大的进一步勘探潜力。通过对断裂系统和断裂活动特点的研究,分析了油气藏类型及其分布规律。认为该区主要发育3个主要断裂带,其中长垣断层存在分段封堵性。油气藏类型主要为构造隐蔽油气藏、岩性油气藏、复合油气藏和低电阻油气藏。针对不同类型的油气藏特征和分布,采取了相适应的滚动勘探思路和技术,取得了显著效果。
Due to its complicated structure and large number of oil-gas reservoirs, the provenance of the Hu-Qing fault zone is only about 37%, which shows great potential for further exploration. By studying the characteristics of fault system and fault activity, the types of oil and gas reservoirs and their distribution are analyzed. It is considered that there are three main fault zones in this area, of which the fault sealing of Changyuan fault is segmented. The types of reservoirs are mainly subtle reservoirs, lithologic reservoirs, composite reservoirs and low-resistivity reservoirs. In view of the different types of reservoir characteristics and distribution, has taken the appropriate rolling exploration ideas and techniques, and achieved remarkable results.
