Abstract
An adjustable fracturing system is provided. In one embodiment, the system includes a fracturing manifold coupled to a fracturing tree to allow the fracturing tree to receive fracturing fluid from the fracturing manifold. The system also includes an adjustment joint configured to be varied in length to facilitate coupling of the fracturing manifold to the fracturing tree. Additional systems, devices, and methods are also disclosed.
Claims16
A system comprising:
- a fracturing manifold;
- a fracturing tree coupled to the fracturing manifold to enable receipt of fracturing fluid from the fracturing manifold;
- an adjustment joint including an inlet, an outlet, and a bore to transmit the fracturing fluid through the adjustment joint, wherein the adjustment joint is configured to be varied in length to facilitate coupling of the fracturing manifold to the fracturing tree;
- and
- a valve coupled between the fracturing manifold and the fracturing tree to control flow of fracturing fluid from the fracturing manifold to the fracturing tree, wherein the adjustment joint is disposed between the valve and the fracturing tree to enable variation in the length of a fluid connection between the valve and the fracturing tree.
2 more elements
An adjustment joint comprising:
- an inlet, an outlet, and a bore to transmit a fracturing fluid through the adjustment joint, wherein the adjustment joint is configured to be varied in length to facilitate coupling of a fracturing manifold to a fracturing tree;
- wherein the adjustment joint includes a pipe connector having a first collar disposed about a first tubular member and a second collar having a flange;
- the first collar includes an interior, threaded surface to engage a mating surface of the second collar;
- the flange of the second collar is coupled to a mating flange of a second tubular member;
- and the pipe connector is configured such that rotation of the first collar causes translation of the second collar with respect to the first collar to vary the length of the pipe connector;
- the first tubular member is received within the second tubular member;
- and the adjustment joint includes a wiper seal disposed between the first tubular member and the second tubular member.
4 more elements
A method comprising:
- adjusting a length of a first adjustment joint in a fracturing system to facilitate alignment of a connection between a fracturing manifold and a fracturing tree in a first dimension;
- adjusting a length of a second adjustment joint in the fracturing system to facilitate alignment of the connection between the fracturing manifold and the fracturing tree in a second dimension different from the first dimension;
- and
- adjusting a length of a third adjustment joint in the fracturing system to facilitate alignment of the connection between the fracturing manifold and the fracturing tree in a third dimension different from the first dimension and the second dimension.
1 more element
An adjustment joint comprising:
- an inlet, an outlet, and a bore to transmit a fracturing fluid through the adjustment joint, wherein the adjustment joint is configured to be varied in length to facilitate coupling of a fracturing manifold to a fracturing tree;
- wherein the adjustment joint includes a pipe connector having a first collar disposed about a first tubular member and a second collar having a flange;
- the first collar includes an interior, threaded surface to engage a mating surface of the second collar;
- the flange of the second collar is coupled to a mating flange of a second tubular member;
- the pipe connector is configured such that rotation of the first collar causes translation of the second collar with respect to the first collar to vary the length of the pipe connector;
- the first tubular member is received within the second tubular member;
- the adjustment joint includes at least one seal in an annular space bound by the first tubular member, the second tubular member, and the second collar;
- the at least one seal includes a first seal and a second seal;
- and the adjustment joint includes a test port extending from the annular space at a position between the first seal and the second seal and through the second tubular member.
6 more elements
A system comprising:
- a fracturing manifold;
- a fracturing tree coupled to the fracturing manifold to enable receipt of fracturing fluid from the fracturing manifold;
- an adjustment joint including an inlet, an outlet, and a bore to transmit the fracturing fluid through the adjustment joint, wherein the adjustment joint is configured to be varied in length to facilitate coupling of the fracturing manifold to the fracturing tree;
- and
- two additional adjustment joints, wherein the adjustment joint and the two additional adjustment joints enable three translational degrees of freedom in aligning a pipe connection between the fracturing manifold and the fracturing tree.
