Embodiment approach

[0074] As an embodiment: the spring striker 114 includes a spring, and the two ends of the spring are respectively connected to the middle parts of the two straight plates, wherein one of the straight plates is fixedly connected to the derrick 103, and the other straight plate is provided with an elastic body (such as a sponge). In order to prevent the straight plate from directly contacting the simulated wellbore 101 and avoid damaging the simulated wellbore 101 .

[0075] As a second embodiment: the spring striker 114 includes a spring, and a cylinder that is sleeved on the spring and has a length less than the natural length of the spring, one end of the spring is vertically connected with the derrick 103, and the other end of the spring is provided with an elastic body (such as a sponge) ). A cylinder is placed on the spring to limit the position of the spring, so as to prevent the spring from deflecting when stressed.

[0076] In the above two implementations, when the s...

Abstract

The invention discloses a shaft simulation device and an oil-gas-water three-phase-flow simulation experiment system and belongs to the field of oil field machines. The shaft simulation device comprises a simulated shaft, a plate-shaped support, a rotary piece, a supporting seat, a derrick, a motor, a reducer, a first pulley, a second pulley, a steel cable and a power controller. One end of the simulated shaft is connected with the plate-shaped support through the rotary piece, the rotary piece comprises an input pipeline perpendicularly communicating with the end of the simulated shaft, and the supporting seat is fixedly arranged on the plate-shaped support and used for fixing the input pipeline. The derrick is perpendicularly connected with the right side wall of the plate-shaped support, and the motor and the reducer are connected through a coupler and arranged on the plate face of the right portion of the plate-shaped support. The first pulley is connected with a transmission shaftof the reducer. The second pulley is located over the first pulley and perpendicularly connected with the derrick through a transverse connecting rod, one end of the steel cable is fixed to the firstpulley, the steel cable sequentially winds across the first pulley and the second pulley to enable the other end of the steel cable to be connected with the simulated shaft, and the power controlleris used for controlling operation of the motor. According to the shaft simulation device, oblique wells with different slopes can be simulated, and leaking cannot occur in the rotating process.

Description

technical field [0001] The invention relates to the field of oilfield machinery, in particular to a simulation wellbore device and an oil-gas-water three-phase flow simulation experiment system. Background technique [0002] In crude oil extraction, multiphase flow phenomena are often encountered. For example, crude oil is generally a three-phase mixed fluid of oil, gas and water. Therefore, the study of three-phase flow of oil, gas and water is of great significance in oil field production. At present, devices such as liquid production profile combination instrument and flow meter can be placed in the oil well to detect the relevant parameters of the crude oil to be extracted, and then formulate a reasonable crude oil recovery plan. The detection standards of industrial profile combination instruments, flowmeters and other devices need to be calibrated by performing three-phase flow simulation experiments in the laboratory, and when conducting simulation experiments, a devi...
