Description

Technical Field

[0001] The utility model relates to the field of oil and gas drilling, in particular to a box-stacked drilling rig base. Background Art

[0002] With the increasing demand for the exploitation of resources such as oil and minerals, drilling rigs, as an important type of engineering machinery and equipment, undertake important tasks in underground exploration and exploitation. However, there are some problems with the traditional drilling rig base, such as unstable structure, complex installation, and difficult maintenance, which limit the performance and work efficiency of the drilling rig. In order to solve these problems, R&D personnel began to explore new base design solutions. The concept of box-stacked drilling rig base came into being. Its design was inspired by the stability of the box structure and the convenience of modular design. By designing the base as a box structure and adopting a modular assembly method, the stability of the drilling rig and the convenience of installation and maintenance can be improved.

[0003] The bases of shallow well drilling rigs in service in China are mostly of two structures: swing-up type and box-block type. The swing-up type base is composed of multiple groups of columns to form a column system. Each group of columns is connected to the left and right upper seats with a pin-axis ear plate. The lifting is based on the principle of parallelogram. The left and right bases are connected with a pull rod. The middle part of the left and right upper seats is composed of a root area, a turntable beam, a winch beam and a table deck. The box-block type base is made up of multiple modules stacked together. The columns are mainly composed of 2 four-column beams and 2 triangular beams. The size of the modules can meet the installation and transportation requirements of mountainous environments and is connected with pin-axis ear plates.

[0004] The two structural forms of the drilling rig base failed to achieve effective utilization of the height space of the base column, and the well site auxiliary equipment could not be integrated on the base structure, and could not adapt to the mountainous environment with a small well site area. The other two types of drilling rig bases use a large number of pin shaft ear plates for connection, and the assembly and disassembly of the base are complicated. In addition, there are many types of pin shafts. During the drilling rig transfer operation, the pin shafts are lost and confused, affecting the on-site installation efficiency.
