Analysis of gas - bearing probability of gypsum - salt rock layer in Lower Majiagou formation of Taba temple Block, Ordos Basin

Beginning with the survey of regional geology, this paper analyzes the geochemical characteristic of source rock, as well as organic matter abundance, maturity and geology evolvement in Lower Paleozoic, Ordos Basia In combination with the geology logging data of Taba temple Block, better gas shows was found in the third member of lower Majiagou formation in Paleozoic. Because of abundant gas source rock and good reservoirs, it is suggested hydrocarbon exploration should be strengthened and new areas should be exploited in Taba temple block.
