The petroleum industry in our country has rapidly developed since recentthirty years

its output has gone up from a few ten-thousand tons in 1949 to 106 million tons in 1979.However

the output of crude oil increased slowly in recent years and seems to come a stop.The reason was not due en-tirely to the deficiency in resources

but was because of paying too muchattentions on development and neglecting oil prospecting and exploration formany years in the plans of oil and gas prospecting work

which resulted inthe increasing rate of crude oil production much higher than that of reser-ves.The authors believe that we have rich oil and gas resources.We havewide prospect region and various reservoir types

but the degree of prospec-ting is very low.Therefore

the prospecting work of oil and gas should bestrengthened as fast as possible to increase greatly new reserves.This paper

in comparing with the trend of recent domestic and foreignoil and gas pros pecting and exploration

points out that our oil and gasprospecting and exploration work later on must find out not only giant

deepand non-anticlinal oil reservoirs but also natural gas

including coal-forminggas;offshore oil and gas prospecting and exploration work should be con-solidated;the prospecting and exploration of middle-small type

shallow

antic-linal reservoirs still should not be neglected owing to Mesozoic and Ceno-zoic continental middle-small basins wides preading in our country.
