摘要
塔河油田位于新疆塔里木盆地北部沙雅隆起南翼阿克库勒凸起上,是中石化储、产量增长的重要基地。2004年中石化西北分公司在九联片地震解释中发现寒武系大型建隆线索。建隆地质属性的确定对于下一步勘探和长远部署具有重要意义。通过对寒武纪造礁生物的分析、实例研究和建隆沉积环境的分析,特别是建隆与火山岩、盐岩体的地球物理特征对比,排除了建隆是盐岩和火山岩的可能,其地球物理特征与已证实为生物礁体可以类比,推测,该建隆是生物礁的可能性很大。
Tabe oilfield, located in Akekule swell of south flank of Shaya uplift in northern Tarim basin, is an important base for incremental reserves and production of Sinopec. In 2004, the clue of Cambrian large-scale build-up was found by Northwest Branch during nine-block seismic interpretation. The determination of the geologic attribute of this build-up is of great significance for tbe nextstep exploration and its long-term deployment. This paper excludes the possibility that the build-up could be salt and volcanic rocks by the analysis of Cambrian reef-building organisms, the case study and the evaluation of sedimentary environment of the build-up, especially by the correlation of geophysical characteristics between the build-up and the volcano and salt body. The analogue from these geophysical characteristics and proved organic reef suggests that this build-up may likely be a bioherm.
