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 oil and gas drilling, in particular to a three-section hydraulic telescopic packaged derrick; the structure of the derrick is a K-shaped front opening, and a number of oil cylinders for changing various working states of the derrick are installed on the derrick, and a two-story platform is installed in front of the derrick , the rear and side of the derrick are equipped with an oil cylinder centralizer, which is characterized in that the derrick is divided into three sections, namely the upper section of the derrick, the middle section of the derrick, and the lower section of the derrick. The derrick is equipped with a bearing device that can keep the derrick in a stretched state and can be remotely controlled, and all the oil cylinders on the derrick can be remotely controlled; Transport and placement, improve drilling efficiency, scientific structure, stable three-section hydraulic telescopic package derrick.

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,...
