Description

Technical Field

[0001] This utility model relates to the field of clamping devices, specifically to a clamping device for a horizontal well dual steam injection pipe. Background Technology

[0002] In heavy oil extraction, steam injection pipes are used to inject steam into horizontal wells to reduce the viscosity of crude oil, making it easier to flow and extract. For example, patent application number 201620185059.7 discloses a horizontal well dual-pipe steam injection string, including a well body, sensor A and sensor B. Steam injection pipe A is located inside the well body, and sensor A is located on the inner wall of steam injection pipe A. A valve is located on the right side of steam injection pipe A, and a sealing gasket is located between the valve and steam injection pipe A, with the sealing gasket located on the valve. The valve is connected to a worm gear, which cooperates with a turbine. The turbine is connected to one end of a connecting rod, and the other end of the connecting rod is connected to a helical gear B. Helical gear B meshes with helical gear A. Helical gear A is connected to one end of a transmission rod, and the other end of the transmission rod is connected to gear B. Gear B meshes with gear A. Gear A is connected to the output shaft of motor B. Steam injection pipe B is located inside steam injection pipe A, and sensor B is located on the inner wall of steam injection pipe B. A ball valve is located inside steam injection pipe A, and the ball valve is connected to the output shaft of motor A. It has the following advantages: When steam is injected into steam injection pipe A, sensor A detects the signal of steam flow and transmits the signal to the controller. The controller controls motor A to rotate, keeping the ball valve closed, and controls motor B to rotate. Motor B drives gear A, gear A drives gear B, gear B drives helical gear A, helical gear A drives helical gear B, helical gear B drives turbine, turbine drives worm gear, and worm gear drives valve, opening the valve and allowing steam injection pipe A to inject steam into the corresponding position. When steam is injected into steam injection pipe B, the valve closes and the ball valve opens. The two steam injection pipes are independent of each other, resulting in better steam injection effect and convenience for users.

[0003] However, the patent still has the following defects: since there is no component in the well body to clamp the steam injection pipe A and the steam injection pipe B, the stability of the steam injection pipe A and the steam injection pipe B during use is generally poor.
