The oil derrick or drilling rig is the main equipment component of an oil drilling rig
Although there are various types of drilling rigs, their basic components are the same, mainly consisting of the rig base, the rig body, the overhead crane platform, the overhead crane frame, the second floor platform (the workbench for lifting and lowering drilling tools), the riser platform (the operating platform for disassembling and assembling water hoses), and the rig ladder. Due to the installation of wellhead devices in the base of drilling rigs and the need to install rotary control heads during negative pressure drilling, the base of drilling rigs is generally very high. Currently, the base height of large and medium-sized oil drilling rigs is generally around 7-10 meters.
