Method for fixing gangue dumping platform in process of using permanent derrick to construct well

Abstract

The invention discloses a method for fixing a gangue dumping platform in a process of using a permanent derrick to construct a well, belonging to derrick construction. The method comprises reinforcement in horizontal direction and reinforcement in vertical direction, wherein the reinforcement in horizontal direction comprises the following steps: installing a rope protective device on derrick legs, welding the rope protective device with a pulling plate into a whole to embrace the derrick legs; connecting a steel wire rope between the derrick legs, leading the steel wire rope to pass through the rope protective device and then clamping the steel wire rope by a steel wire rope clip; and connecting a board clip I at one end of the pulling plate with the steel wire rope and connecting the other end of the board clip I with a steel beam B. The reinforcement in vertical direction comprises the following steps: installing a suspension-dragging steel wire rope on the derrick legs above the gangue dumping platform, leading the steel wire rope to pass through the and then clamping the steel wire rope by a steel wire rope clip; and installing lifting lugs on a steel beam A, installing a rope protective ring on a pulling plate clamp, leading one end of the steel wire rope to pass through the rope protective ring to be connected with a pulling plate clamp and leading the other end of the steel wire rope to be connected with a turn-buckle through the rope protective ring and connecting the other end of the turn-buckle with the lifting lug. The method has the effects of reasonably solving the relation between the platform and the derrick and the relation between the platform and a well mouth, and expanding the usable area of the well mouth to the greatest extent.

Description

technical field [0001] The invention relates to a gangue turning platform, in particular to a method for fixing the gangue turning platform when a permanent derrick is used to build a well. Background technique [0002] In order to shorten the construction period and reduce the permanent modification time, the permanent derrick is often used as a temporary sinking derrick at present. There are currently two ways to set up the gangue platform: one is the method of using the inner casing, and the other is the method of setting the temporary derrick. The former has complex construction procedures, small usable platform area, high technical requirements, and many potential safety hazards. It is often necessary to change the original design, prolong the preparation time for wellbore construction, and require a large amount of maintenance and restoration during use, occupying wellhead space, and reducing The utilization rate will inevitably affect the efficiency of mechanized fac...

The former has complex construction procedures, small usable platform area, high technical requirements, and many potential safety hazards. It is often necessary to change the original design, prolong the preparation time for wellbore construction, and require a large amount of maintenance and restoration during use, occupying wellhead space, and reducing Utilization rate will inevitably affect the efficiency of mechanized facilities for wellbore operations; the latter will increase the installation and removal of temporary derricks, prolong the preparation time for wellbore construction and permanent installation preparation time, and take up a long construction period
