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。
For a long time, exploration workers in Tazhong area have been perplexed by the stratigraphic belts, reservoir genesis and main controlling factors of the carbonate target layer in the central and western Tarim Basin, resulting in the lag of oil and gas exploration and development in the central and western Tarim Basin, Block. In order to promote oil and gas exploration and development in this block, the stratigraphy, lithology, electrical property, physical property, petroleum-bearing property and reservoir of the central and adjacent parts of the Tarim Basin are stratified through regional stratigraphic correlation, well-earthquake calibration and stratification Cover the combination of the corresponding relationship to solve the adjacent block Ordovician seismic events on the fault axis, can not be continuously tracked the problem; the central and western regions of the “good three” under the middle and lower Ordovician, you can clear It is of great guiding significance for the exploration and development in the next step to depict the formation causes, types of reservoirs and the distribution of oil and gas in the purposeful reservoirs in the central and western parts of the tower.
