Description
Technical field
The utility model belongs to petroleum works field, is specifically related to a kind of for simulating oil pumper analogue experiment installation.
Background technology
In perpendicular rings vacant duct, heterogeneous rotational flow is the main study subject of multiphase fluid mechanics, is also very common in actual field produces and one of major issue.Such as: when drilling well is vertically crept into, the gas-liquid-solid multiphase flow in drilling rod and pit shaft looping space moves; When utilizing screw pump lifting to recover the oil, the gas liquid two-phase flow in sucker rod and oil pipe looping space.In view of the complexity of Multiphase Flow, experimental study is still current main approaches.Existing vertical annular space flooding test device can only carry out the simulated experiment up and down reciprocatingly of sucker rod, lacks the vertical annular space Multiphase Flow analogue experiment installation that sucker rod can carry out rotating.
Summary of the invention
The purpose of this utility model is to solve the problem lacking the vertical annular space Multiphase Flow analogue experiment installation that sucker rod can carry out rotating at present, and provides perpendicular rings air fluid two-phase rotational flow analogue experiment installation in a kind of oil pumper pit shaft.
In this oil pumper pit shaft, perpendicular rings air fluid two-phase rotational flow analogue experiment installation comprises upper and lower transparent pit shaft, sucker rod, liquid reserve tank, the top of sucker rod is fixed with buncher straight down, the output shaft of buncher and the upper end concentric of sucker rod are fixed, and the side of buncher is fixed on body of wall or support body by connecting rod; The top of transparent pit shaft and bottom are fixed with pressure sensor and temperature pick up, and pressure sensor and temperature pick up are all connected with data acquisition module; The top of described liquid reserve tank is connected by the top of reflux line with transparent pit shaft, the bottom of liquid reserve tank is connected with the input of screw pump, screw pump is connected with frequency converter, screw rod delivery side of pump is connected with the input of gas flowmeter and the input of fluid flowmeter, and the output of gas flowmeter and the output of fluid flowmeter are also connected with the bottom of transparent pit shaft after connecting; The upper end of described transparent pit shaft and lower end all seal and are fixed with seal disc, and the center of seal disc has can through the through hole of sucker rod, and sucker rod coordinates with through hole slipper seal.
The utility model has following beneficial effect:
In this oil pumper pit shaft, perpendicular rings air fluid two-phase rotational flow analogue experiment installation can complete the multiphase flow rotational flow Rule of sucker rod in vertical ring-shaped space.In actual experiment, first start buncher, take into account fluid flowmeter by gas flow again and regulate the gas-liquid mixed ratio be input in transparent pit shaft, by gathering the upper and lower temperature of transparent pit shaft and pressure data, in conjunction with the flow pattern of medium in transparent perpendicular rings blank pipe, just can carry out heterogeneous rotational flow law study in perpendicular rings vacant duct, and then provide theoretical direction for actual field produces.Meanwhile, this device can form a set of closed circulating system, facilitates the control operation of experimenter.The utility model has diverse in function, the advantage that easy to operate and range of application is large.
