The invention discloses a wellhead oil extraction device. The device comprises a first four-way pipe; first flat valves are installed on the two sides of the first four-way pipe; a second flat valve is installed at the top of the first four-way pipe; and a second four-way pipe is installed at the end, away from the first four-way pipe, of the second flat valve; third flat valves are installed on the two sides of the second four-way pipe; a fourth flat valve is installed at the top of the second four-way pipe; and rotating handles are arranged on one sides of the first flat valves, the second flat valve, the third flat valves and the fourth flat valve. Through arranged handles, when the valves need to be driven by the rotating handles, the handles are unfolded from handle grooves, check blocks abut against the handles, then the handles on the two sides are held by the two hands, the rotating handles are driven by the handles to rotate clockwise, slipping of the rotating handles is avoided through the handles, and the valves can be opened conveniently through the rotating handles.
Description
technical field [0001] The invention relates to the technical field of Christmas trees, in particular to a wellhead oil production device. Background technique [0002] The wellhead oil production device is also called the Christmas tree. The Christmas tree is a wellhead device used to exploit oil such as self-flowing wells and mechanical production wells. It is the main equipment for controlling and regulating oil and gas production at the top of the oil and gas well. [0003] When the existing wellhead oil production device is in use, it is often necessary to control the valve through the turning handle. However, the wellhead oil production device is used for oil production operations, so that crude oil will be attached to the turning handle, which will easily cause the turning handle to slip, and it is inconvenient to open the valve. , is inconvenient to use, therefore urgently needs the technology that can improve the wellhead oil recovery device structure, perfects this...
