摘要: 巴麦地区奥陶系鹰山组储层类型及优质储层发育主控因素是该区下步油气勘探的关键性问题。通过对巴麦地区奥陶系钻井的岩心观察、薄片分析及测井解释判别,认为目前钻遇的储层以裂缝型为主;从微量元素地球化学和碳氧同位素化验结果分析,储层为封闭的埋藏成岩条件下的裂缝和沿裂缝流动形成的溶蚀孔洞。受加里东和海西期古构造带控制的裂缝发育带是鹰山组优质储层分布的有利区;和田古隆起长期暴露形成的岩溶高地和岩溶斜坡具备发育表生岩溶储层的条件,是下步值得关注和研究的重要领域。Abstract: Reservoir type of the Ordovician Yingshan Formation in the Bachu-Maigaiti region and the main controlling factors for favorable reservoir generation are the keys for further petroleum explorations in the region.Based on core observation,thin-section analysis and well-logging interpretation,the Ordovician reservoir is fracture-pore type.According to trace element and carbon or oxygen isotope analyses,the reservoirs include fractures and corrosion pores formed under closed burial diagenetic conditions.Fracture generation belt controlled by the Caledonian and Hercynian movements is favorable for the Yingshan Formation reservoir distribution.Karst plateau and slope formed by long-time denudation of the Hetian ancient uplift are qualified for epidiagenetic karst reservoir generation,and are important for further exploration.
