3. Fig. 2. Pressure diagrams at moments (a) - 1.62 ms, (b) - 2.5 ms, (c) – 3.5 ms. Calculation parameters: liquid – in the gas-liquid zone: a mixture of oil and water with volume contents ao0 = 0.75 and aw0 = 0.25, methane gas: ag0 = 0.001, a = 1.25 mm, x1 = 2.95 m, x2 = 3.05 m, x2l = 3.3 m, x1l = 2.7 m, x2g = 3.2 m, x1g = 2.8 m, ∆pl0 = 0.5 MPa, po00 = 830 kg/m3, pw00 = 1000 kg/m3,vo = 10-2 m2/s, vw = 10-6 m2/s, Co = 1225 m/s, Cw = 1500 m/s, pg00 = 50.19 kg/m3, cg = 2220 J/kg K, λg = 0.03 W/m K, T0 = 300 K, p0 = 7.0 MPa

6. Fig. 5. Waveforms of reflected signals for the D3 sensor: bold lines correspond to the volume content of gas in the bubble core (a) – ag0 = 0.001 and (b) – ag0 = 0.01, thin lines correspond to the case of the absence of a bubble core in the jet (ag0 = 0). Volume content of oil and gas in the area of a multiphase jet: ao0 = 0.75, aw0 = 0.25. The other parameters are the same as in Fig. 2

7. Fig. 6. The same as in Fig. 5. The bold line in both pictures corresponds to the case when the volume fraction of oil in the liquid phase of the bubble zone is ao0 = 0.75 (aw0 = 0.25), the thin one is ao0 = 0.25 (aw0 = 0.75). The volume content of the gas is (a) – ag0 = 0.001, (b) – ag0 = 0.01. The other parameters are the same as in Fig. 2
