EVALUATION OF OIL AND GAS RESOURCE IN CENTRAL TARIM BASIN, CHINA

Abstract

Abstract:

A systematic evaluation of source rock from central Tarim Basin is provided and the scale of oil and gas generated from source rock in the area is calculated with the method of basin simulation. The study shows that the migration and accumulation of oil and gas chiefly occurred during or before the period of tectonic movements in early Paleozoic and late Paleozoic. The
early accumulated oil and gas had been destroyed severely. The tectonic evolution in the area is very important to the migration and accumulation of oil and gas. Cambrian and Lower Ordovician source rocks generated and expelled oil at early time, so they paid little contribution to the oil reservoir discovered at present. However, the natural gas expelled from these source rocks at late time is easy to accumulate. The period for middle and upper Ordovician source rocks to generate and expel oil lasted a very long time, so the oil and gas from this source rock provided essential contribution to the oil reservoir in the area.
