n: The method of measuring thickening time indirectly.

n: a thickening-time tester having a stirring apparatus to measure the relative thickening time for mud or cement slurries under predetermined temperatures and pressures.

n: a thickening-time tester with a stirring appratus to measure the relative thickening time for mud or cement slurries under predetermined temperatures and pressures.

n: A thickening time tester having a stirring apparatus to measure the relative thickening time for drilling fluid or cement slurries under predetermined temperatures and pressures.

a device with rotating paddles, used to check the pumpability and set time of cement slurries.

n: The mixture of diatonite and cement. The main defects are long thickening time and low intensity.

n: the physical characteristic of a cement slurry that determines its ability to be pumped.

n: the ability that transimites cement slurry by pump.

a measurement of a fluids capability to be pumped. Usually refers to cement slurry and is also called the thickening time.

n: a cement in which the thickening time is extended by adding a chemical retarder.

n: The cement that can delaying solidify.

n: a substance added to cement to prolong the setting time so that the cement can be pumped into place. Retarders are used for cementing in high-temperature formations.

n: A chemical additive used to increase the thickening time of cement slurries or similar fluids that may have a limited pumping time. The increased pressure and temperature typically associated with deep wellbores requires the use of such performance-enhanc

a chemical that slows a reaction. In cementing, retarders slow the set time of the cement and prolong the pumpability of the cement.

n: a manufactured cement in which the thickening time is extended by the use of a coarser grind, the elimination of the rapid hydrating components in its composition, and the addition of a chemil retarder. API classes N, D, E, and F are slow-set cements.

n: The cement that can delaying solidify.

n: the amount of time required for cement to reach an APIestablished degree of consistency, or thickness. Thickening time begins when the slurry is mixed. thief n: a device that is lowered into a tank to take an oil sample at any depth. The sample will subsequently be used to deter- mine the quality and S&W content of the oil in the tank. v: to obtain a sample of oil from a tank using a thief.

n: The ultimate time that viscosity of cement slurry coming to 10Pa.s


the time that a cement slurry will remain pumpable at temperature and pressure.

n: The apparatus that be used to measure thickening time.
