摘要： A system connecting one more flow lines and includes a connector housing and a connector. The connector housing comprises a first connection passage formed through a wall of the connector housing. The connector is disposed withing the connector housing. A first annular flow path connection is formed between the connector housing and the connector. The first housing annular flow path connection is formed by a first housing annular flow path connection groove. The first housing annular flow path connection groove is formed in an outer side surface of the connector. Alternatively, the first annular flow path connection is formed by a combination of the first housing annular flow path connection groove axially aligned with the first connector annular flow path connection groove. The first connection passage through the connector housing intersects with the first annular flow path connection. A related method includes connecting inserting the connector into the connector housing.

摘要： A shear ram system includes an upper block positioned to transition from a first location outside a bore to a second location within the bore, the upper block including a blade control arm having a first contact surface. The shear ram system includes a lower block positioned to transition from the first location outside the bore to the second location within the bore, the lower block including a second contact surface proximate the first contact surface. The shear ram system includes a progressive gap between the first contact surface and the second contact surface larger at a first end than at a second end such that a first gap distance at the first end is greater than a second gap distance the second end.

摘要： The invention relates to elastomeric compositions containing filler particles that are predominantly two-dimensional in shape. The elastomeric compositions exhibit significantly improved thermal, chemical, and mechanical properties as compared with elastomers containing conventional fillers such as natural clay, carbon black, and carbon fiber. In addition, the elastomeric compositions of the invention exhibit improved resistance to solvent-induced swelling and to unwanted permeation of gases such as hydrogen sulfide. The invention also provides a method of forming such elastomeric compositions and methods of using such elastomeric compositions to prepare elastomeric articles with improved resistance to thermal, chemical, and mechanical stresses.

摘要： Transducer assembly for an offshore drilling riser, in an example, includes a spool for connecting into the riser and a protrusion extending around the side wall of the spool. A recess extends around the protrusion between upper and lower sloping surfaces. Upper transducer bores are spaced around the protrusion and extend from the upper sloping surface downward and inward into the spool bore and lower transducer bores extend from the lower sloping surface upward and inward into the spool bore. A base of a rigid non-metallic material is located in each of the transducer bores. A seal ring extends around a cylindrical exterior portion of each of the bases and one of the transducer bores. An acoustic transducer element is mounted to the outer end of each of the bases. The transducer assembly can detect drilling fluid and form sealing.

摘要： A system for coupling a first pipe segment to a second pipe segment includes a pin coupled to the first pipe segment, the pin having a first outer diameter and a second outer diameter, the second outer diameter forming a recess along at least a portion of the pin. The system also includes a box coupled to the second pipe segment, the box having an opening, the opening receiving at least a portion of the pin, wherein at least a portion of a wall of the opening includes threads. The system further includes a rotating threaded collar arranged within the recess, at least a portion of the rotating threaded collar including mating threads configured to engage the threads of the box, wherein the rotating threaded collar is rotatable about the pin.

摘要： A method for use in well drilling, development, completion, and production, including supplying hydraulic pressure to a tubing spider having at least one actuating component, generating position data from a position sensor based on the position of the actuating component, generating pressure data from a pressure sensor based on the pressure supplied to the spider, and automatically handling tubing with the spider by actuating the actuating component by adjusting pressure supplied to the spider based on the position data, the pressure data, and a prescribed control algorithm. The method may be implemented as part of a system including a tubing spider having at least one actuating component, sensors detecting hydraulic pressure supplied to the spider and the position of the actuating component, and a programmable logic controller capable of generating spider control data to control the spider based on data from the sensors and a prescribed control algorithm.

摘要： A packer unit to be used in an annular blowout preventer. The packer unit includes an elastomer body including a compound of a nitrile rubber base polymer having a polymer chain, and a quantity of fluorine atoms attached to the polymer chain. The compound includes between 50 and 60% of the nitrile elastomer, between 25 to 35% carbon black, and the rest includes other materials. The quantity of fluorine atoms comprises short-chain fluorocarbon chain molecules The quantity of fluorine atoms displaces at least an equal quantity of hydrogen atoms from the polymer chain when the elastomer body is fluorinated.

摘要： A blowout preventer (BOP) includes a pressure driven operator that is equipped with a balancing circuit to offset pressure inside the BOP. The operator, which is used to drive a ram, includes a piston, coupled to the ram by an operator arm, and a balance arm on a side of the piston opposite the operator arm. Pressure from inside the BOP communicates to an end of the balance arm opposite the piston and exerts a force to drive the ram radially inward.
