The invention relates to a simulation system for a pressure-back method test. The simulation system specifically comprises a wellbore simulation device, a formation simulation device and a control andsignal processing device, wherein the wellbore simulation device comprises a pressure-bearing casing pipe string, a wellhead connecting device, a bottom connecting device and a plurality of flow parameter monitoring sensors; the formation simulation device comprises a formation fracturing simulation device, a fluid pressure-back channel, a wellhead flow-dividing device and a ground collection device, the formation fracturing simulation device is placed in an artificial well bottom on the lower portion of the wellbore simulation device and connected with the pressure-bearing casing pipe stringthrough the bottom connecting device of the wellbore simulation device, an annular space between the pressure-bearing casing pipe string of the wellbore simulation device and an outer layer casing pipe serves as the fluid pressure-back channel, the wellhead flow-dividing device is connected with the fluid pressure-back channel and the ground collection device, and the ground collection device isused for collecting fluids pressed out through a pressure-back method; and the control and signal processing device comprises a computer, a control signal data transmitter and a signal collector, anda user receives signals of the flow parameter monitoring sensors, processes and saves the signals and controls setting of relevant parameters of the formation simulation device.
Description
technical field [0001] The invention relates to the technical field of gas intrusion monitoring and well killing, in particular to a pressure-back method test simulation system and simulation method. Background technique [0002] With the rapid economic development in recent years and the continuous exploitation of oil, the number of well invasion and blowout accidents has also increased. These accidents also bring great losses to the oil exploration work, and cause life or property damage to operators; therefore, well control technology is becoming more and more important. As an unconventional well killing method, the pressure back method is usually used for well killing when the reservoir contains toxic and harmful gas invasion, or blowout and well killing when the circulation cannot be established because the drill pipe is not in the well. Advantage. However, the successful implementation of the pressure-back method depends on factors such as well killing equipment, wel...
