Abstract:
Based on the analyses of sedimentary sequence, lithology, particle size, and logging data from more than 20 drilling wells in Maxian region on the northern margin of the Qaidam Basin, the sedimentary characteristics and its evolution of Paleogene Lower Xiaganchaigou Formation were studied. The results showed that braided fluvial facies were the main sediment types of this formation, including channel bar, point bar, and flood plain, and the environment with water withdrawal was the main depositional environment in this period. According to the fine structural interpretation of 3D seismic data, seismic attributes can also well illustrate the changes of depositional environment of the Lower Xiaganchaigou Formation: In the early period, the sediments were mainly from northeast of the Maxian region, and a little from the north, and sandbodies were mainly dominated by the northeastern provenance; Along with the basin development, the northeastern provenance gradually migrated westward, and its supplies also decreased, in contrast, the supplies from the northern provenance increased; In the later period, the above two provenances got closed, and then developed large and contiguous sandbodies. Preliminary conclusions about the environmental evolution of Lower Xiaganchaigou Formation in Maxian region and three sandbodies distribution can provide reliable geological data for the next oil and gas exploration.
