Problems solved by technology

Due to the limited height, the second-floor platform of this type of derrick can only discharge double-section drill pipes, which leads to long time-consuming drilling operations and low efficiency in drilling and running-in conditions, and the installation of the top drive system is inconvenient. Possess a strong ability to deal with underground accidents

Embodiment 1

[0034] A three-section hydraulic telescopic suit derrick, the derrick structure is a K-shaped front opening, a number of oil cylinders are installed on the derrick for changing various working states of the derrick, a two-story platform 6 is installed in front of the derrick, and oil cylinders are installed on the rear and side of the derrick for straightening derrick 3, the derrick is divided into three sections, which are the upper section 1 of the derrick, the middle section 2 of the derrick, and the lower section 4 of the derrick. The carrying device that keeps the derrick in tension and can be controlled remotely, and all cylinders on the derrick can be controlled remotely.

[0035]In this embodiment, the upper section 1 of the derrick is equipped with a bearing device A5 for limiting the upper section 1 of the derrick to the middle section 2 of the derrick when the derrick is stretched, and the lower section 4 of the derrick is installed with a bearing device A5 for holdi...

Abstract

The invention relates to the field of drilling of petroleum and natural gas, in particular to a three-section hydraulic telescopic sleeved headframe. The three-section hydraulic telescopic sleeved headframe adopts the structure of a K-shaped front opening; a plurality of oil cylinders for transformation of various working states of the headframe are mounted on the headframe; a racking platform is mounted in front of the headframe; oil cylinder centering devices are mounted at the back and on the side surface of the headframe; the three-section hydraulic telescopic sleeved headframe is characterized by being divided into three sections, namely an upper headframe section, a middle headframe section and a lower headframe section; the upper headframe section is matched with the inner wall of the middle headframe section; the middle headframe section is matched with the inner wall of the lower headframe section; a bearing device capable of enabling the headframe to keep the stretching state and performing remote control is mounted on the headframe; all the oil cylinders on the headframe can be in remote control; According to the invention, the provided three-section hydraulic telescopic sleeved headframe is more intelligent, meets requirements of more working conditions, is convenient for transportation and placement, and scientific and stable in structure, and improves the efficiency of drilling operation.

Description

technical field [0001] The invention relates to the field of oil and gas drilling, in particular to a three-section hydraulically telescopic jacketed derrick. Background technique [0002] At present, most of the derricks equipped with vehicle-mounted drilling rigs in the domestic oil industry are mast-shaped portable derricks with jump ropes, two hydraulically telescopic sections, and the derricks are tilted at a small angle. There are a total of 12 jumping ropes connecting the upper end of the lower section of the derrick, the crown block and the second-floor platform. The jumping ropes provide stability for the derrick. The rope needs to adjust the sag, and there is a large human error, which leads to uneven force on the jumping rope and uneven force on the derrick. Due to the use of the jump rope structure, if the effective height of the derrick is increased to meet the three-section vertical root requirements, each section of the derrick needs a jump rope to stabilize,...
