摘要:
在沉积微相研究工作基础上,针对陇东地区延长组长3、长4+5油层小层对比复杂砂层厚度、岩性横向变 化大的特点,对陇东地区延长组长3、长4+5油层碎屑岩稀土元素、碳酸盐岩岩屑以及轻重矿物组合分布进行 了综合分析研究,认为区内三叠系延长组沉积物源主要来自北东向和西南向,在陇东地区北东物源的沉积边界 大约在南梁—华池地区,西南物源的沉积边界大约在悦乐地区,两者间为砂岩层厚度、岩性、物性变化大的混源 区。通过对不同物源区的储层特征分析对比,认为在陇东地区延长组沉积物物源分布范围、组合特征是影响储 层发育的主要因素之一。
Abstract:
Based on the factual situations of Yanchang Formation in Longdong area, the rare earth elements, carbonate rock detritus, light and heavy mineral are analyzed. It is thought that there are mixed sources in the area. The directions of the provenance are mainly in the northeast and southwest. It is preliminary judged that the frontier of the northeast provenance probably lies in Nanliang-Huachi area and the frontier of the outhwest provenance probably lies in Yuele area. Finally, through the comparision of characteristics of three oilfield reservoirs, it is found that the provenance is an important factor for the formation of reservoir in Longdong area.
