Abstract：Equivalent dipole layer method is currently considered as most complete reduction of gravity data to a horizontal plane theoretically, but the method cannot process the practical data with a giant amount of data. The main reason lies on difficulty to deal with a large-scale and high-order integral equation. The paper uses wavelet compression algorithm to realize the compression and order-reducing solution of large-scale Fredholm integral equation. The theoretical model computation showed the reduction of gravity data to a horizontal plane can reach a very high precision when the compression ratio is 40.5%. The paper also discussed the influence of different compression ratio on the reduction of gravity data to a horizontal plane and illustrates the application effect of the method by the result of the reduction of gravity data to a horizontal plane in Y oilfield of southern China
