| 摘 要： | 塔中地区经历多期构造运动,导致下古生界地层抬升遭受风化剥蚀,先后形成3期古潜山,发育2套潜山岩溶储层。研究了潜山岩溶储层的发育特征及其控制因素,并对其发育的有利区进行了预测。同时,对塔中地区烃源岩、储盖条件、运聚条件及成藏过程等成藏条件进行了分析,认为奥陶系岩溶储层与其上覆的志留系、石炭系泥岩可构成良好的储盖组合,油源断裂、不整合面、岩溶孔缝洞体系构成了复杂的油气输导网络。塔中低凸起奥陶系潜山油气藏成藏过程复杂、期次多,但喜山期构造调整是最终成藏的关键。在此基础上,对勘探有利区带进行了预测,认为中央断垒带中、东段及其北部围斜地区(塔中15、16井区)和塔中低凸起东部潜山区(塔中1井区-塔中5井区-塔中48井区)为有利目标区。

| Abstract: | The Tazhong area had experienced multi-stage tectonic movements,resulted in weathering denudation in lower Palaeozoic uplift,and formed buried hills in 3 stages,including 2 sets of buried hill karst reservoirs.This paper studies the development characteristics and control factors of the buried hill karst reservoirs and predicts favorable zones.Also analyzed are the source rock,reservoir-seal assemblage,migration and accumulation process in the Tazhong area.It is believed that the Ordovician karst reservoir ... |
