FIELD: oil and gas industry. ^ SUBSTANCE: proposed method comprises oil sampling from the well in the amount of about 1.0 to 3.0 ml at whatever point, preferably at the hole face. The oil sample is subjected to homogenisation to produce a homogeneous mass, the viscosity factor of this sample 1, 2, 3 is determined at appropriate P=P1, T=T1 P=P2=P1, T=T2>T1 and P=P3>=P2, T=T3=T2, where P1 P2, P3, T1 T2, T3 are pressure P and temperature T in every of the three measurements of viscosity of the given sample. Then mathematical formulae are used to determine parameters , , . Now, pressure PL P0 and temperature TL, T0 are determined at the levels of perforated holes and well head, respectively, to define viscosity factors L, 0 of oil sample using mathematical formulae. Finally mathematical formulae are used to calculate oil well production rate Q. ^ EFFECT: higher accuracy of measurements, shortened time required for them, lower costs. ^ 1 dwg |
