The essential forms of the earth's crust-movement are the crust-waves

which result in formation of the framework of the wavy-mosaic structure of the crust.Almost all of the mineral resources

as well as oil and gas occurrences are controlled by the frameworks of the mosaic structure of thecrust.According to the data of the known oil fields in China

the evidences of wavy-mosaic structural controls of the oil-gas resources are as follows:All of the major oil and gas basins in China are controlled by the structuralnetwork of the earth's crust;The source areas and the areas of oil accu-mulation are under control of the belts of wave crests and troughs in their prevailing directions

the migration of the wave movement dominates the changes in space of the source areas and the areas of oil accumulation;The approximate spacing of the same order structures

the directions and paral-lelism of the structural belts

and the forms and regularities of the arrange-ment of the crust blocks

all of these can be used to predict the unknownoil and gas fields or areas.In planning the prospecting and exploration work for oil and gas field

the above-said hypotheses will considerably exert an effect on oil and gas prospecting.
