Sliding Sleeve Door Function

Equalizing pressure between an isolated formation and the tubing string.

Sliding sleeve door function.

Nnmodular design permits conversion from a model cmd to model cmu or vice versa by only changing the upper and lower subs. Empacador de camisa deslizable. It incorporates an internal sleeve that when open enables communication between the tubing and tubing casing annulus. The sliding sleeve is assembled to and forms part of the tubing string.

A nipple profile in the top sub and a polished bore in the bottom sub are standard features and allow accessory tools such as a side door choke or separation tool to be set across the durasleeve device. The model cm series sliding sleeves are high performance equalizing sliding sleeves which allow communication between the tubing and annulus for circulation or selective zone production. Sliding sleeve wp 5000 10000psi profile type f the sls series sliding sleeves are used in the separate zone production to switch the tubing and casing annulus. A sliding sleeve is a standard component for the completion of an oil or gas well.

There are two main categories of sliding sleeves. Manage pressure and fluid flow between tubing and casing. Components optimized with respect to function and strength. Hoerbiger sliding sleeve hub systems featuring perfectly matched components are used by automobile and transmission manufacturers worldwide.

Sliding side door sleeves are a robust and reliable method of isolating the tubing id from the reservoir for a variety of reasons including but not limited to fluid loss control activation of hydraulically set down hole tools zonal stimulation and production and icd shutoff for ultimate production control.

Their main uses are to shut off flow from one or more reservoir zones or to regulate pressure between zones. Acting as downhole control valves sliding sleeves can also be used to circulate fluids from the annulus to the tubing above the production packer or to inject water into individual zones during waterflood operations.
