Abstract:
Locating in the piedmont tectonic belt of the Kunlun Mountain, the southern Hetian area in the southwestern Tarim Basin is a piedmont tectonic belt with multiple stages and types. Complicated geological structure background makes it difficult for speed research in the study area. The velocity analysis and variable speed graphics software of Hongliu company deals with velocity field problem in complicated area with big stratigraphic dip angle. It solves the problem of deep prediction in the main purpose layer, and ensures the accuracy of drilling design.
