摘要： A downhole choke and associated methods provide enhanced efficiency and accuracy in well sampling and testing operations due to its capability for substantially minimizing the amount of time needed to establish steady state flow conditions in a well, and the ability to sample fluids downhole at varying downhole flow restrictions. In a described embodiment, a downhole choke is operable to restrict fluid flow therethrough by applying a predetermined fluid pressure to an annulus formed between the choke and the wellbore. The downhole choke has an axial flow passage formed therethrough, a portion of which has interchangeable flow areas. The flow areas are interchanged upon application of the predetermined fluid pressure, and again interchanged upon expiration of a time delay. One of the flow areas permits substantially unrestricted fluid flow therethrough, and another of the flow areas permits restricted flow therethrough.

摘要： A system for selectively preventing free flow in a tube includes an in-line occluder disposed in the tube and an actuator pad for creating a flow path between the tube and the occluder. The actuation pad presses towards the occluder from a single side and stretches the tube to create a large flow path. The occluder stem is strengthened to resist deformation and damage from the forces applied by the actuator pad.

摘要： An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by moving an engagement member into engagement with the tubing segment to deform the tubing segment and open a flow channel. Unless force is applied to keep the engagement member in contact with the tubing segment, the tubing will return to the first, closed position.

摘要： A conduit cleaning method and apparatus for connection to a fluid inlet feed line and an outlet drain line utilizes a housing assembly having an inlet portion, an outlet portion, and a bight portion. The inlet and outlet portions have sloped leg sections which provide increased fluid flow through the bight to disperse accumulated debris. Rotatable shafts inside the housing accommodate paddles or jets to facilitate in retrieval or dispersal of obstruction.

摘要： A pressure monitoring system allows for more accurate and reliable measurement of the pressure inside of a tube in a pump. The pressure monitoring system prevents movement of the tubing or a change in size of the tubing due to external forces applied to the pump, eliminating inaccuracies due to handling of the pump during use.

摘要： An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing and a mounting structure. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by placement in the mounting structure. However, unless force is applied to keep the occluder mechanism in the mounting structure, the occluder will move relative to the mounting structure and return to the first, closed position.
