STUDY OF SOURCE ROCKS IN AND AROUND NORTH TARIM UPLIFT WITH THE GEOLOGICAL THEORY OF HYDROCARBON BEARING BASIN

There have been different opinions on source rocks since the oil discovery of Shacan No.2 well in north Tarim. The author considers that the problem can never be solved if different analytical indices are taken for a single crude oil. With the geological concept of hydrocarbon bearing basin, considering the evolution condition of the basin, i.e.sufficient hydrocarbons from tne source rocks, and favourable conditions of migration and accumulation, the source rocks is suggested to be of Mesozoic age rather than Pale-aozoic, howevei. Different ideas of source rock lead to different stragic decisions and arrangements and thereby different results of exploration.
