An oil well wellhead blowout preventer and system

Abstract

The invention relates to the field of oil field production equipment, in particular to an oil well wellhead blowout preventer and an oil well wellhead blowout preventer system. The wellhead blowout preventer of the oil well includes a shell part and monitoring equipment. The bottom of the shell part is provided with a first through hole, and the top is provided with a second through hole, which are used for the passage of the pipeline connected with the wellhead blowout preventer of the oil well; The bottom of the part forms a first sleeve part with a return hole inside the first through hole; the monitoring equipment is arranged in the wellhead blowout preventer of the oil well, and is used to monitor the change of the fluid in the shell part and feed it back to the control device. The invention can fully ensure that no landing oil is generated within its effective load range, and control the mis-emission of harmful gases. It not only reduces the loss of landing oil and improves the overall oil production, but also avoids the generation of landing oil, and controls the overall monitoring and processing capabilities of harmful gas emissions, significantly improving the comprehensive pre-control of potential safety hazards. The operation data information of each oil well is collected in real time during operation. Provide rich data detail support for optimization operations.

Description

technical field [0001] The invention relates to the field of oilfield production equipment. In particular, it relates to an oil well wellhead blowout prevention device and system. Background technique [0002] Since the implementation of the new "Safety Production Law" and the new "Environmental Protection Law", the environmental protection and safety requirements for oil field production have become more and more stringent. Specifically, the management of landing oil produced during oil well operations has changed from the original allowing part of the landing oil to the present It is strictly forbidden to drop oil. In the prior art, the treatment of landing oil mainly has two aspects: [0003] On the one hand, blowout prevention devices are installed at the wellhead of oil wells to control the source of ground oil. The blowout prevention devices in the prior art are adjusted during oil well testing, workover, and completion of oil wells during oil field construction. We...
