Benefits of technology

[0005]A self propelled or trailer frame is provided with a cradle on which the tool for subterranean use can be assembled preferably in a shop protected from the weather. The tool is transported to a well site and the truck is positioned for deployment. The cradle is on a sub-frame that can translate off the end of the truck bed to get an end of the tool closer to the wellhead. The truck has a hydraulic li

Problems solved by technology

Not only are there safety issues with this procedure but such assembly procedures at the well site are expensive and take time thus delaying resumption or initiation of production.

Embodiment Construction

[0008]FIG. 1 shows a trailer 10 with a wheel assembly 12 near the rear end 14. Spaced apart booms 16 and 18 are mounted on the trailer 10 to assist in assembly of the components of an ESP 20 on a carriage 22. Carriage 22 has a leading end 24 and a trailing end 26. Carriage 22 is supported from a subframe 30 and can be lifted at the leading end 24 by a hook 32 that is supported by a truck mounted derrick, not shown, or some other support structure that is provided over the wellhead, also not shown. Carriage 22 can roll along the subframe 30 such as on a wheel assembly 28. The ESP 20 can be initially assembled onto the carriage 22 using the booms 16 or 18 or other lifting equipment and secured to the carriage for over the road transport.

[0009]The subframe 30 is mounted on a base frame 34 that is in turn supported off the truck bed 36. A hydraulic linkage 38 can tilt the subframe 30 by urging its trailing end 26 to slide along the base frame 34 using a sliding member 40 whose shifted p...

Abstract

A self propelled or trailer frame is provided with a cradle on which the tool for subterranean use can be assembled preferably in a shop protected from the weather. The tool is transported to a well site and the truck is positioned for deployment. The cradle is on a sub-frame that can translate off the end of the truck bed to get an end of the tool closer to the wellhead. The truck has a hydraulic linkage to upend the nearest end to the wellhead to a point close to where a hook in a derrick that is over the wellhead can be attached to the tool for hoisting the tool up so as to lift it off the cradle with minimal side loading on the derrick as the tool lower end leaves the cradle. The tool can be an electric submersible pump and can be used for delivery as well as removal of the tool through a wellhead.

Description

FIELD OF THE INVENTION[0001]The field of the invention is service vehicles for land based wells and more particularly vehicles that allow the assembly and placement of electric submersible pumps in position for insertion or removal from a subterranean location.BACKGROUND OF THE INVENTION[0002]Self propelled and trailer service vehicles designed to be placed near a wellhead and having a tilt up derrick have long been in use to service wells in certain circumstances. These derrick structures pivot into position over the cab or off the rear of the vehicle whether self propelled or a trailer. Some examples of such designs are U.S. Pat. Nos.: 4,591,006; 4,743,175; 4,901,805; 5,174,389; 5,524,716; 5,711,382; 5,931,238; 6,003,598; 6,530,432; 7,111,689 and 7,249,629. U.S. Pat. No. 4,981,080 shows a pipe carrier on wheels to go into a larger access pipe and carry a submersible pump to deliver fluids that flow into the collection pipe to a remote storage tank.[0003]Electric submersible pumps ...
