南美前陆盆地隐蔽油气藏勘探
|
摘要
针对南美西北部前陆盆地斜坡带低幅度构造-岩性复合圈闭隐蔽性强、识别难度大、油藏边界难以准确描述等技术难点,开展了围绕油气藏特征及分布规律、层序地层及沉积微相、地震资料精细处理和解释的综合勘探方法研究.在厄瓜多尔奥连特盆地的研究成功指导了中方区块的勘探实践,并在开发区加密井的优选和部署中发挥了关键作用.形成了一套适用于南美前陆盆地斜坡带复合型隐蔽油气藏的勘探方法和识别技术.
This research was aimed at hunting complex subtle trap with low-relief structure and lithologic reservoir.Most of these traps were very hard to be detected and the boundary of reservoir was indisdinct.We focused on the regularity of oil distribution,sequence stratigraphy and sedimentary microfacies,fine seismic data processing and interpretation.The intergrated exploration method has applied secessfully in both exploration and development of some blocks in Oriente Basin of Ecuador.As a summary of the research and application,a set of method and technique was formed and applicable in complex subtle reservoir of foreland basin in South America.
