摘要：
The crude oil in the Upper Part of the Lower Ganchaigou Formation in the Yingxi area of the Qaidam Basin, China, was formed in a strongly reducing and high-salinity sedimentary environment with algae as the main parental material. The crude oil in this area possesses the typical geochemical characteristics of saline lacustrine crude oil. The crude oil is mainly derived from source rocks of its own horizon, indicating that the reservoirs in the study area have self-generation and self-storage reservoir features.
