annulus造句

tubing-casing annulus

annulus tendon ineus communis

The returned carrier fluid enters the internal flow path at the base of the tool before crossing over to the annulus above the packer assembly, isolating the annulus.

Numerical calculation of unsteady flow of viscoelastic fluid in eccentric annulus

With vacuum outgassing taken into acount, the equivalent conductivity of annulus is analyzed in detail.

The model consists of perforation, wellbore, cement casing, oil layer, micro-annulus and transverse fracture.

The optimal project position for demonstrating tricuspid annulus in angiography:an experimental study

Large eddy simulation of self-oscillation pulsed water jet drawing in annulus fluid

The annulus testing technique, in which the instrument is up and down through the annulus space between the tubing and casing, is regarded as the best testing method at home and abroad.

Use limitation to be in in shuttle root B by the needlework annulus of shuttle sharp hook outward surge.

Detection of mitral annulus displacement with speckle tracking imaging:a new technique for evaluation of global systolic function of left ventricle

The slurries are injected into well before running in casings with closed bottom end and then running casing make the slurry be squeezed into annulus to improve cementing bonding in small annulus.

Its goods according to the tradition is distributing center mode annulus haven of the center and build.

The float shoe prevents reverse flow, or U-tubing, of cement slurry from the annulus into the casing.

The positive cells increased after perforation in the annulus and handle of malleus region,but no immunostaining cells were found at the edge of perforation.

Mechanical sticking can be caused by junk in the hole, wellbore geometry anomalies, cement, keyseats or a buildup of cuttings in the annulus.

The clinical research of radiofrequency ablation of atrial flutter along the line between tricuspid annulus and eustachian valve/ridge in 21 cases.

This paper reports the experiment of air-water two-phase flow in a small scale laboratory models and in a 1000 m-deep well with annulus configurations.

Numerical calculation of average flow rate of the unsteady flow of a viscoelastic fluid in eccentric annulus with the inner cylinder reciprocating axially

Ortherwise, the eccentric gas anchor, gas lift valve and surface check valve are installed to automatically unload the gas from the deeper layer and annulus between the tubing and the casing.

The effects of the different tripping size were not alike, 20% tripping annulus was the best size for a pipe flow to obtain fully developed turbulence in the experiment.

As small tears in the disc's outer layer (annulus) develop and enlarge over time, the jellylike inner layer (nucleus) may bulge outward, causing pressure on the spinal cord and nerves.

It is attached to the bottom end of a retrievable packer, and opens and closes automatically with the change of the pressure of the hot fluid column in the tubing-casing annulus.

PCTH tested valve has the function of being open state constantly and that keeping on open after annulus pressure relived out makes it much handy and be liable to be used.
