Abstract Parker's formulas in different forms have been obtained by making logical derivations in quite simple way,Parker's formula which reveals the relationship between density distribution function,density interface function and gravity function.Different Parker's for mulas,such as Parker's formula with density varying exponentsaily,and Parker's formula with densiiy depending an polynomial,wiil be very useful in oil gravity survey. The newly developed multiplier and shift sampling techniques are used in numerical calculation so that the accuracy of density-variable forward modeling is equivalent to that of constant Lensity forward modeling in space domain. Theoretical modeling and practical examples prove the techniques fully effective.
