Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a table-top rotatable environmental protection well workover operation platform and its use method. This device solves the problem that the existing workover operation platform has single function, poor weighing performance, and cannot integrate wellhead automatic operation tools to adjust the operation position. The process is complicated, time-consuming, labor-intensive, heavy pollution, and endangering the safety of operators. It has automatic wellhead operation tools that can be integrated. According to the layout of the well site, the operation position of the automatic tool can be conveniently adjusted by rotating the table, and it can effectively handle the spilled water in the operation. The characteristics of oil pollution on the platform, safety and environmental protection

Abstract

The invention discloses an environment-friendly workover work platform with a rotatable table top and an application method. The environment-friendly workover work platform comprises a work platform body, adjustable supporting legs, a recyclable ladder, a dirt receiving box, a liquid level sensor, a rotating support, a hydraulic drive slewing bearing, a self-sealing blowout preventer, a mechanicalarm mounting base, an upper shackle hydraulic clamp guide rail, a control box, a pipeline and the like. The problems that an existing workover work platform is single in function and poor in weighingperformance ad cannot integrate wellhead automatic work tools, when the work position is adjusted, procedures are complex, time and labor are wasted, pollution is severe, and the safety of operatorsis harmed are solved; the environment-friendly workover work platform has the characteristics that wellhead automatic work tools can be integrated, according to the well site arrangement situation, the work positions of automatic tools can be conveniently adjusted by rotating the table top, oil stains scattered on the platform during work can be effectively treated, and safety and environmental protection are achieved; and the functions of wellhead rapid mounting, oil pipe mud scraping, sealing between oil casings, mud collection, hydraulic detection, hydraulic steering of the table top of theplatform, height adjustment and the like can be achieved.

Description

Technical field[0001]The invention relates to an oilfield workover wellhead operation auxiliary device, in particular to an environmentally friendly workover work platform with a rotatable table top and a use method.Background technique[0002]After an oil well has been exploited for a period of time, different conditions will occur in the well, such as blockages, damage to the pumping pump, etc., affecting oil production. Workover operations are required at this time. Domestic workover operations are mainly performed directly at the wellhead or using simple operation platforms. During the work, overflow in the well and oil pollution when lifting the pipe string will not only affect the safety of workers, but also bring pollution to the environment. .[0003]With the advancement of technology, mechanized equipment has gradually emerged to replace part of manual operations, such as pneumatic slips, manipulators, automatic hydraulic tongs, and power catwalks. Most of the existing workover...
