Well fracturing manifold apparatus
A fracturing system can include a fracturing manifold coupled to a plurality of fracturing trees. The fracturing manifold may include adjustment joints that enable adjustment of the length of the fracturing manifold. The fracturing manifold can also include pivot joints that allow angular displacement of portions of the fracturing manifold with respect to other portions. The adjustment and pivot joints can accommodate spacing and elevation differences between the fracturing trees.
1. A fracturing system, comprising:
a first well fracturing tree;
a second well fracturing tree;
a first connection block; and
a second connection block;
wherein the first connection block is coupled in fluid communication with the first well fracturing tree via two valves so as to provide a straight flow path to route fracturing fluid from the first connection block into the first well fracturing tree through the two valves, the second connection block is coupled in fluid communication with the second well fracturing tree via two additional valves so as to provide a straight flow path to route fracturing fluid from the second connection block into the second well fracturing tree through the two additional valves, and the first connection block is in fluid communication with the second connection block through a portion of a manifold trunk line.
2. The system of claim 1 , wherein the first well fracturing tree and the second well fracturing tree bear at least a portion of the weight of the manifold trunk line.
3. The system of claim 1 , wherein the two valves and the two additional valves are gate valves.
4. The system of claim 1 , wherein the portion of the manifold trunk line includes a plurality of pipe sections.
5. The system of claim 1 , wherein the portion of the manifold trunk line includes an adjustment joint that enables variation in the length of the portion of the manifold trunk line.
6. The system of claim 1 , wherein the portion of the manifold trunk line includes a pivot joint.
