Embodiment 1
[0016] Such as Figure 1-2 As shown, a digital control blowout preventer for oil wells includes a double ram blowout preventer 2, the two ends of the double ram blowout preventer 2 are connected to the motor 12 through a reduction mechanism 8; the double ram blowout preventer Two laser sensors 1 are symmetrically installed on the upper neck of the 2, one emits laser light and the other receives laser light; the laser sensor 1 is connected to a PLC control system, and the PLC control system is connected to the motor control through a drive module, so that After receiving the optical signal, the PLC controls the movement of the motor through the drive module connected to it, so as to achieve the following effects: when the oil well is working normally, the optical rod does not fall off. After the laser is emitted, it is blocked by the optical rod, and the other sensor cannot receive it. When the laser light signal is received, the motor action will not be triggered. Once the op...

The invention discloses an oil well numerical controlling blowout preventing device. The oil well numerical controlling blowout preventing device comprises a double-gate-plate blowout preventer; the two ends of the double-gate-plate blowout preventer are connected with a motor through a speed reducing device in a transmission mode, so that the power and torque of the motor are reduced; the double-gate-plate blowout preventer is provided with a polished rod, two laser sensors are installed on the two ends of the polished rod correspondingly, one laser sensor emits a laser, and the other laser sensor receives the laser; and the laser sensor is connected with a PLC controlling system, and the PLC controlling system is connected with the motor through a driving module in a controlling mode, so that movement of the motor is controlled by a PLC through the driving module which is connected with the PLC after the PLC receives light signals. The oil well numerical controlling blowout preventing device has the advantages that not only is input of human cost reduced, safety of construction personnel is guaranteed, but also the oil well numerical controlling blowout preventing device can quickly response and shut down an oil well after crisis situations such as overflowing, well kick and well blowout are detected, so that the production process is more safe and reliable.
Description
technical field [0001] The invention relates to an oil well blowout preventer, in particular to a numerically controlled oil well blowout preventer, which belongs to the field of oil well blowout preventers. Background technique [0002] In oil and gas drilling and production, when drilling through high-pressure oil and gas layers, drilling blowout accidents are prone to out-of-control accidents. At this time, it is necessary to install a set of equipment at the wellhead of the drilling. In case of overflow, well kick, blowout and other critical situations, the blowout preventer needs to be activated quickly and shut down the oil well. If it fails, it will lead to a series of vicious accidents caused by blowout. At present, in my country's oilfield systems, double ram blowout preventers are often used and manually controlled. The manual double ram blowout preventer requires manual operation during use, which increases the workload of the workers and increases the cost inve...
