The invention discloses a height detection method and device for mobile drilling equipment, and the method comprises the steps: obtaining liquid density data, first air pressure measurement data, second air pressure measurement data and preset height data, the rubber pipe is arranged between the mobile drilling equipment and a fixed point position of a derrick, a first end of the rubber pipe is arranged on the mobile drilling equipment, a second end of the rubber pipe is arranged on the fixed point position of the derrick, and the first air pressure measurement data is a measurement value of a wireless pressure sensor arranged at the first end of the rubber pipe; the second air pressure measurement data is a measurement value of a wireless pressure sensor arranged at the second end of the rubber tube, and the preset height data is height data of a fixed point position of the derrick; and according to the liquid density data, the first air pressure measurement data, the second air pressure measurement data and preset height data, height detection of the mobile drilling equipment is carried out. The drilling efficiency can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of oil and gas drilling, in particular to a method and a device for detecting the height of mobile drilling equipment. Background technique [0002] In the tripping operation of oil and gas (including shale gas) drilling, it is necessary to monitor the height of the drilling device driven by the top of the mobile drilling equipment and the state of the lifting ring in real time, so as to prevent the top driving ring from colliding with the second floor of the derrick and other serious damage caused by it. accidents. [0003] At present, the commonly used methods for detecting the height of mobile drilling equipment are to calculate the height of the top drive through the speed measuring mechanism installed on the drawworks drum, or to detect the height of mobile drilling equipment by means of laser ranging, but these methods have independent mechanical moving parts or light-emitting parts that are prone to a...
