摘要：

长期以来，塔中地区勘探工作者一直困惑于塔中西部地区碳酸盐岩目的层的层位归属、储层成因及油气藏主控因素，致使塔中西部地区油气勘探开发滞后于塔中其他区块。为促进该区块的油气勘探开发工作，通过区域地层对比，井—震标定与统层，理顺了塔中西部与相邻区块地层、岩性、电性、物性、含油气性及储盖组合的对应关系，解决了相邻区块上奥陶统地震同相轴错断，不能连续追踪的问题；将塔中西部地区“良三段”划归中下奥陶统后，可以清晰地刻画塔中西部地区目的层储层成因、油气藏类型及油气分布规律，对下一步勘探开发具有重大的指导意义。

关键词: 区域地层对比, 井震标定, 地层划分与对比, 储层成因, 油气藏类型

Abstract:

For a long time,exploration workers of Tazhong area have been puzzled by the layer of belonging,reservoir genesis and main-control factors of hydrocarbon accumulation in carbonate layer of western area,causing the oil-gas exploration and development in western behind other blocks.To promote oil-gas exploration and development in western Tazhong area,We have given stratigraphic correlation between the western Tazhong area and adjacent area in lithology,electric property,physical property,oil-gas bearing property and reservoir-seal assemblage have been straightened out by doing regional stratigraphic correlation and well-seismic calibrate,which can solve the problem that seismic event cannot be continuously traced due to seismic event discontinuity in adjacent area.After belonged the third section of Lianglitage Formation to the Lower-Middle Ordovician,the new strata classification and correlation scheme can clearly depict the distribution of different strata,reservoir genesis and type,and hydrocarbon distribution law in the western Tazhong area,which is of great significance to the next step of exploration and development.

Key words: Recognition of strata, Well-seismic calibrate, Standard section, Subzone classification and correlation, Reservoir type
