Abstract
A connector block having a single piece body may be configured for use in a Christmas tree. The connector block may include an axial bore formed therethrough, one or more valve chambers, passing fully through the connector block and intersecting the axial bore, one or more frac bores, extending from an outer surface of the connector block to the axial bore; and, one or more wing bores, extending from the outer surface of the connector block to the axial bore.
Claims26
A connector block, configured for use in a Christmas tree, the connector block comprising a single piece body having:
- an axial bore formed therethrough;
- one or more valve chambers, passing fully through the connector block and intersecting the axial bore;
- one or more frac bores, extending from an outer surface of the connector block to the axial bore;
- and
- one or more wing bores, extending from the outer surface of the connector block to the axial bore.
A connector block, configured for use in a Christmas tree, the connector block comprising a single piece body having:
- an axial bore formed therethrough, the axial bore having an axis;
- two valve chambers, passing fully through the connector block and intersecting the axial bore, each of the two valve chambers having an axis;
- a frac bore, extending from an outer surface of the connector block to the axial bore, the frac bore having an axis;
- and
- two wing bores, extending from the outer surface of the connector block to the axial bore.
A Christmas tree comprising:
- a connector block comprising:
- an axial bore formed therethrough;
- one or more valve chambers, passing fully through the connector block and intersecting the axial bore;
- a frac bore, extending from an outer surface of the connector block to the axial bore;
- and
- one or more wing bores, extending from the outer surface of the connector block to the axial bore;
- and
- one or more valve assemblies, each of the one or more valve assemblies disposed within a wing bore, and each of the one or more valve assemblies comprising a flow control element disposed within the axial bore;
- and a means of actuating the flow control element;
- one or more wing valve assemblies, the one or more wing valve assemblies being connected to the connector block, such that a longitudinal bore of each of the one or more wing valve assemblies is fluidly connected to one of the one or more wing bores;
- a frac connector connected to the connector block, such that a bore of the frac connector is fluidly connected to the frac bore
- a lower component connected to a lower end of the connector block, such that an axial bore of the lower component is fluidly connected to the axial bore;
- and
- an upper component connected to an upper end of the connector block, such that an axial bore of the upper component is fluidly connected to the axial bore.
A method of constructing a Christmas tree, the method comprising:
- forming a connector block;
- attaching a frac connector to a connector block, such that a bore of the frac connector is fluidly connected to a frac bore of the connector block;
- attaching one or more wing valve assemblies to a connector block, such that a longitudinal bore of each wing valve assembly is fluidly connected to a wing bore of the connector block;
- attaching a lower component to a lower end of the connector block, such that an axial bore of the lower component is fluidly connected to the axial bore;
- and
- attaching an upper component to a upper end of the connector block, such that an axial bore of the lower component is fluidly connected to the axial bore.
