Patent UA-45446-C2 (UA)
Inventor: KHOTULIOV HENADII PETROVYCH
Filed: 1998-10-23
Abstract: According to the proposed method, in order to assess viscosity of liquid in porous layer of the oil or gas deposit, the seismic signal characteristics are adjusted for mating them with the pulse characteristics obtained within the upper and lower boundaries of the studied deposit. The mating state is determined from the maximal reflected seismic signal amplitudes. By using phase coincident components of the received reflected seismic signals, the ratios between the signal parameters are determined from the corresponding mathematical expressions. According to these parameters, the coefficients are calculated that characterize absorption of the longitudinal seismic wave by the oil or gas deposit layer. For complete assessment of the deposit quality, using the calculated absorption coefficients, the average values and correlation function of these coefficients are determined.
