Method for stabilizing oilfield equipment

摘要

Systems and methods for stabilizing a riser or similar object against motion can include engaging two or more cylinder apparatus to the object. Communication of fluid between cylinder apparatus, responsive to a force on the object, can limit movement of the object, such as through extension or retraction of pistons within the cylinders. The cylinder apparatus can include internal channels that can accommodate coiled tubing, slickline, wireline, and similar conduits or devices, enabling operations to be performed through the cylinders, independent of their position.

主权项

1. A method for stabilizing a riser against motion, the method comprising the steps of:
engaging a first cylinder apparatus with a first portion of the riser; engaging a second cylinder apparatus with a second portion of the riser, wherein the second cylinder apparatus is spaced apart from and is in fluid communication with the first cylinder apparatus; communicating a fluid between the first cylinder apparatus and the second cylinder apparatus to control a change in length of the first cylinder apparatus and the second cylinder apparatus to limit a motion of the riser; communicating the fluid between the first cylinder apparatus and the second cylinder apparatus to control the relative movement between a first tubular member and a first housing of the first cylinder apparatus; and communicating the fluid between the first cylinder apparatus and the second cylinder apparatus to control the relative movement between a second tubular member and a second housing of the second cylinder apparatus.
