Embodiment Construction

[0016] Such as figure 1 with figure 2 As shown, a double-platform hydraulic lifting casing device of the present invention includes a base platform 1, an upper lifting platform 2, a lifting hydraulic system, and a lifting cylinder arranged between the base platform 1 and the upper lifting platform 2 3. A guardrail 10 and a movable door 11 are installed on the outer circumference of the upper lifting platform 2, so as to facilitate the installation and replacement of the lifting cylinder 3 and the upper lifting platform 2 does not need to be loaded during the casing cutting operation. Above the base platform 1 Four upstanding main frame columns 4 are fixed by bolts Ⅱ22, and a circular corridor 23 is arranged outside the main frame column 4 of the upper lifting platform 2. Guardrails 24 are installed on the circular corridor 23, and a lifting hydraulic system control is set on the circular corridor 23. panel and hydraulic slip control panel, the control panel is placed on the ...

Abstract

The invention discloses a dual-platform hydraulic lifting casing device, which belongs to the technical field of operation equipment and includes a base platform, an upper lifting platform, a lifting hydraulic system, and a lifting cylinder arranged between the base platform and the upper lifting platform , an upstanding main frame column is fixed above the base platform, and a fixed beam is connected to the top of the adjacent main frame column; a lifting cylinder is connected and fixed on the base platform and inside the main frame column, and the lifting cylinder The hydraulic cylinder push rod is connected to the bottom of the upper lifting platform, and the double wellhead platform is adopted, which occupies a small space and is suitable for offshore operation environment; the hydraulic system is used to drive the hydraulic cylinder to lift the top platform instead of the driving system of the drilling and repairing machine, and the equipment setting is convenient and effective. The construction procedure is simplified, the operation success rate is improved, the deficiencies of the existing technology are effectively made up, and the needs of the actual situation are met.

Description

technical field [0001] The invention belongs to the technical field of operating equipment, and in particular relates to a double-platform hydraulic lifting casing device. Background technique [0002] The application and development of petroleum and natural gas has become the most important source of energy and production and living materials in the world. As a result, the exploitation of oil and natural gas has spread all over the world as a basically mature industry, but how to deal with the aftermath after the exploitation has also become a serious problem. After the offshore platform abandons the well in the prior art, a workover rig or a drilling rig is generally used to lift the casing to recover the casing. The ground space is large, and the process is complex and numerous, which affects the working efficiency. Therefore, a dual-platform hydraulic casing lifting device is needed to solve the above problems. Contents of the invention [0003] The invention aims at...
