摘要
Through making full use of the data obtained from field geologic investigation, deeply analyzing reflecting characteristics of the bottom of Paleogene, and logically selecting tectonic theories of orogeny, structural model of Kedong structural belt is set up. The results are obtained from structure-stratigraphy balance restoration of the geological section that structural shorten ratio of Kedong structure in Quaternary is 36.7% and structural shorten rate is about 7.52 mm/a. Tarim oilfield company drilled Kedong 1 on June 14, 2009 based on the structural model and high commercial hydrocarbon flow is obtained on April 4, 2010, which is significant to the exploration in the southwestern Tarim Basin.
