摘要:

塔里木盆地台盆区下古生界碳酸盐岩油气资源十分丰富。早期研究认为碳酸盐岩油气受控于礁滩体与风化壳岩溶储层,油藏呈准层状大面积分布,但近期的评价和开发实践发现油气富集与断裂带密切相关。立足新采集的三维地震等资料,阐明了台盆区的走滑断裂具有构造样式多样性、纵横结构分段性、形成演化多期性与继承性等特点,构建了走滑断裂带油气复式成藏地质模型。最新钻探发现,受走滑断裂控制,大型碳酸盐岩缝洞体呈线状、带状和羽状集中分布于走滑断层1.5 km范围内的破碎带上,且走滑断裂规模越大,缝洞体越发育。生产动态数据剖析与成藏分析表明,走滑断裂带上分布着90%以上的高效井,在大型走滑断裂及其分支断裂的顶端、走滑断裂张扭部位油气更为富集。在塔里木盆地台盆区超深层海相碳酸盐岩的油气勘探开发中,形成的"聚焦断裂带、突出富集段,横向扩边、纵向拓层"勘探开发一体化思路是推动油气藏效益开发的关键。

Abstract:

The Lower Paleozoic carbonate rocks in the platform of Tarim Basin are abundant in oil and gas resources. Early studies suggest that carbonate oil and gas reservoirs are controlled by reef flat composites and weathering crust karsts, and are distributed in quasi-layered large area. However, recent evaluation and development practices have indicated that oil and gas enrichment is closely related to fault zone. Based on the newly acquired 3D seismic data, it is clarified that the strike-slip faults in the platform are characterized by diverse structural styles, vertical and horizontal structure segmentation, multi-stage and inheritance of formation and evolution; the geological model of multiple hydrocarbon accumulation in strike-slip fault zones has been established. The latest drilling practice reveals that under the control of strike-slip faults, large carbonate fracture-cavity bodies are concentrated in the fracture zone within 1.5 km of the strike-slip faults in linear, banded and pinnate shapes. The larger the scale of the strike-slip fault is, the better the development of the fracture-cavity body is. The analyses of production performance data and hydrocarbon accumulation show that more than 90% of high-efficiency wells are distributed in the strike-slip fault zones. Oil and gas are mainly accumulated at the top of the large strike-slip faults and their branch faults as well as the transtensional zones. In the exploration and development of ultra-deep marine carbonate rocks in the platform of Tarim Basin, the integrated exploration and development approach of "focusing on fault zones, highlighting hydrocarbon-enriched sections, horizontally expanding boundary and vertically expanding horizons" is the key to promote the profitable development of oil and gas reservoirs.

Key words: strike-slip fault, carbonate rock, fracture-cavity body, reservoir comtrolling and accumulation controlling, Tarim Basin
