Patent number: 10352805Abstract: A hinged structure includes a hinge that is actuatable using a hydraulic cylinder. A method of monitoring a load applied to the hinged structure involves leaking the hydraulic fluid from the hydraulic cylinder in a way that compensates for expansion of the hydraulic fluid caused by variations in temperature of the hydraulic fluid. The method further involves measuring the pressure of the hydraulic fluid in the hydraulic cylinder. The hydraulic cylinder may be part of a coiled tubing injector. The load applied to the hydraulic cylinder may be used to indicate an overload of the tubing guide.Type: GrantFiled: October 26, 2016Date of Patent: July 16, 2019Assignee: National Oilwell Varco, L.P.Inventors: Timothy S. Steffenhagen, William Benjamin White

Patent number: 9581009Abstract: The invention pertains to methods and apparatus for monitoring loads on an arched tubing guide of a coiled tubing injector caused by tension on coiled tubing. The load is sensed by a load sensor, for example, a load cell placed in a strut that supports the arched tubing guide, or in a load pin or load cell placed within the structure arched tubing guide or the connection of the arched tubing guide to a frame for the coiled tubing injector, at a location where the load is representative of the load placed on an arched tubing guide by tension in the coiled tubing. The load sensor generates a feedback signal. The load is monitored, either by an operator or a controller, and torque applied to a reel around which the tubing is wound is adjusted to avoid, or in response to, excessive loads on the arched tubing guide.Type: GrantFiled: October 15, 2013Date of Patent: February 28, 2017Assignee: National Oilwell Varco, L.P.Inventors: Timothy S. Steffenhagen, William Benjamin White, David W. McCulloch

Patent number: 9236781Abstract: A modified planetary gear box and arrangement of the gear box with a drive motor permits electrical, optical or other types of cabling or wiring to be passed through the planetary gear box along its axis of rotation. The planetary gear box drives or rotates a reel of coiled tubing. Electrical, hydraulic, optical and other types of line for lowering into a well bore through the coiled tubing is passed through a passageway through the center of the planetary gear box, into one end of a hub of the reel, and then into the coiled tubing, which is injected into the wellbore. The other end of the hub of the reel is able to be connected to a swivel joint that can be connected to a pump for pumping fluid into the coiled tubing.Type: GrantFiled: November 21, 2013Date of Patent: January 12, 2016Assignee: National Oilwell Varco, L.P.Inventor: William Benjamin White
