Differential Sticking

The Differential Sticking is a kind of simulating test instrument with multi-functions. It can be used to measure the filtration rate of drilling fluids and the adhesive character of mud cake under the conditions of normal temperature and middle pressure (0.7MPa), as well as under the conditions of normal temperature and high pressure (3.5MPa). The operations are facilitated. It is also characterized by its high precision, little repetitive error and accurate test results. The instrument can be extensively applied in the oil fields, research institutions and laboratories, etc.

  • HPHT Differential Sticking Tester is a kind of simulative and multifunctional experiment and testing instrument. This instrument can measure the filtration loss of drilling fluid under normal temperature with medium pressure (0.7MPa) and normal temperature with high pressure (3.5MPa), and the adhesion performance of filter cake.

  • Differential Sticking Tester in model NF-2 is a simulative test and analysis instrument, which is mainly used to monitor the friction coefficient between drilling tools and borehole drilling fluid in deep wells, so as to treat drilling fluid in time, improve its lubrication performance and prevent sticking accidents.

  • Frictional Coefficient Tester model in NZ-3A is used to evaluate the quality and reasonable compatibility of drilling fluid lubricants.

  • Differential Sticking Tester Model NF-2 - Most incidences of stuck pipe are caused by differential-pressure effects. Excessive differential pressures across lower-pressure permeable zones can cause the drillstring to push into the wellbore wall where it becomes stuck. When differential sticking occurs, spotting fluid can sometimes free the drillpipe.

  • Frictional Coefficient Tester Model NZ-3A is a kind of simulated test and analysis instrument, which is mainly used to monitor the viscosity coefficient between drilling tool and drilling wall mud in drilling. It improve the mud's lubrication performance, prevent the occurrence of stuck drilling accident, and provide accurate and reliable data for ensuring rapid and safe drilling.

  • HPHT Differential Sticking Tester Model GNF-1 - The Model GNF HTHP Differential Sticking Tester is a kind of simulating test instrument with multi-functions. It can be used to measure the filtration rate of drilling fluids and the adhesive character of mud cake under the conditions of normal temperature and middle pressure (0.7MPa), as well as under the conditions of normal temperature and high pressure (3.5MPa).
