Abstract

Abstract:

Pre-Mesozoic unconformity is an important unconformity in Kuchedong Area，which is the direct product of the
late Hercynian movement. Based on 3D seismic interpretation data，combined with well drilling data and regional geology，
we analyzed the main unconformity types，planar distribution of pre-Mesozoic unconformity and its control over oil and gas
reservoirs. The research shows that the types of the unconformity can be divided into parallel unconformity，abnormal unconformity，
truncation unconformity and overlaping unconformity. Parallel unconformity mainly occurs in Akekule uplift，abnormal
unconformity exists in the eastern part of the Yakela faulted uplift，and truncation unconformity and overlaping unconformity
occur in Kuqa Depression. There are two types of unconformity related traps；stratigraphic overlaping trap above the unconformity
surface and buried hill traps below the unconformity. Pre-Mesozoic unconformity is favorable oil and gas lateral migration
channel. Oil and gas migrate along the unconformity from the depression center to south，and enter unconformity related traps
forming oil and gas reservoirs.

Key words: pre-Mesozoic unconformity, trap, hydrocarbon migration, Kuchedong Area, Tarim Basin
