DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP 1. Introduction The RIGCHINA High-Temperature, High-Pressure (HTHP) Dynamic filter press measures filtration properties under varying dynamic down-hole conditions.A motor driven shaft fitted with a propeller turns at varying speeds inside a standard 500mL HTHP cell. Speed settings from 0 to 800 RPM (under no strain) impart laminar or turbulent flow to the fluid inside the cell, and by varying the shaft length, the shear stress may be increased or decreased. The power is driven to the stirring shaft by a timing belt that is easily...

DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP an SCR controller. Power is transferred to the stirring shaft by a timing belt and sheave at a 1:1 ratio. The RPM is indicated directly on a digital tachometer whose pickup is on the motor shaft. The tachometer is calibrated for operating on 60 Hz or 50 Hz. 1.1 Document Conventions The following icons are used as necessary in this instruction manual. CAUTION. Describes a situation or practice that requires operator awareness or action in order to avoid undesirable consequences. MANDATORY ACTION. Gives directions that, if not observed,...

DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP 2. Safety To safely operate the instrument, the user must understand how the equipment works and how to correctly assembly it. Improper assembly, operation, or the use of defective parts, may cause of cell leakage or failure that could result in serious injury and damage. The cell and other components are hot during operation. The operator should be aware of these hot areas and avoid contact with them. Burns can result from touching hot parts of the equipment during normal operation. These instruments are electrically heated. As...

DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP nitrogen gas cylinder or the nitrogen supply system must be built into the laboratory. Nitrogen cylinders must be secured to meet safety standards. Maintain the pressure regulators in good condition. Never use oil on pressure regulators. Leaking pressurizing systems should be repaired or replaced. Gauges, fittings and hoses should be kept in good condition and any leaks should be promptly located and corrected. 2.2 Safe Heating Caution should be exercised by all personnel operating or working near the instrument while it is in operation...

DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP 3. Features and Specifications The Model DHF-1 HTHP Dynamic Filter Press is an instrument used to measure the filter loss of drilling fluids and cement slurries used in deep wells. It can be applied in the following aspects: 3.1 The experiments of static filtration and mud cake preparation. The temperature range is from room temperature to 232℃ and the maximum of working pressure of mud sample cup is less than 7.1MPa. Pressure difference of filtration is 3.5MPa. The filtration area is 22.6cm2. 3.2 The experiments of dynamic filtration...

DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP 4. Installation 1. Carefully unpack the unit and place it on a stable surface near a power outlet. Unpack and unwrap each of the component pieces. 2. Unscrew the T-screws (counter-clockwise) on the pressure manifold to make sure both regulators are completely closed. Connect a Nitrogen cylinder (at least 1,500 PSI) to the center inlet on the pressure manifold. 4.1 Refer to the following photo for a complete view of the assembled unit.

DRILLNG FLUID TESTING INSTRUMENTATION Dynamic Filter Press HTHP The recommended the initial pressure and back pressure of filter cylinder for different tested temperatures are listed in the following table. 5.1 Preparation before experiments: Assemble the pipe-manifold package on the gas cylinder according to Fig.11 and fastened with the G5/8 screw cap. Make sure the pressure regulating handle is in a free state and then open the air source. At this time, the reading of middle pressure gage among pipe-manifold should be great than 8MPa. Link firmly the two burst resisting hoses with corresponding...
