Detailed Description

The industry’s only true dynamic filtration system for conducting filter cake formation and permeability analysis for drilling fluids optimization Utilizing a wide range of available filter mediums, the DYNAMIC HPHT filtration system can be heated and pressurized to provide the closest possible simulation of down-hole conditions. Several safety features have been designed into the system to protect the user and help ensure reliable test results. The filter medium is a thick-walled cylinder with rock-like characteristics to simulate the build-up of filter cake on the formation. The filter medium is available in varying porosities and permeabilities to simulate down hole formations. Filtration occurs radially from the inside of the filter core to the outside. At the same time, the filter cake is formed on the inside of the filter core to simulate filter cake formation on the wall of a borehole. Following completion of a test, the filter cake can be inspected visually. A polished stainless steel shear bob runs through the central axis of the filter core. The shear bob is rotated to produce a concentric cylinder-type shear across the filtration surface. The LCD display allows monitoring of real-time test results, which are printed for further analysis and filing of test results. The DYNAMIC HPHT filtration system also features an interface port, which allows downloading of ASCII-formatted data to a personal computer. The system is fully automatic with a built-in computer controller. Through menu-driven software, the user can establish up to 20 sequence steps to program the following testing parameters: Temperature Pressure Differential pressure Shear rate For Operational and Safety features, see the Product Brochure.

A motor-driven shaft fitted with propellers turns at varying speeds inside a standard 500 mL HTHP cell. RPM settings from 1 to 1600 RPM impart laminar or turbulent flow to the fluid inside the cell. By varying the shaft length, the shear stress may be increased or decreased. Power is driven to the stirring shaft by a timing belt that is easily accessible for quick adjustment and removal. Other features include a variable-speed motor controlled through an SCR controller. RPM is indicated on a digital tachometer. The test procedure is exactly the same as that in the standard HTHP filtration test. The only difference is the fluid circulates inside the cell while filtrate is being collected. Since the filter medium is conventional disk material, the results are comparable with those of other laboratories or for comparing historical trends. Features: Variable-speed electric motor, ½ HP permanent magnet DC Auxiliary pipe connection for the cell top cap. Plug may be removed to add additional fluid additives. Safety-calibrated rupture disk guards against overpressure Motor and stirring shaft RPM operate at a one-to-one ratio Adjustable thermostat from 100° to 500°F Optional filter permeabilities available Size: 12" x 15.5" x 36" (31 x 39 x 91 cm) Weight: 95 lb (43.1 kg) Crated Size: 31" x 21" x 40" (79 x 53 x 102 cm) Crated Weight: 184 lb (83.5 kg)
