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. It can also test the filtration loss of drilling fluid samples under high temperature (~ 170℃)with high pressure (3.5MPa).
The instrument is mainly composed of bracket, mud cup, tee, pressure cylinder, receiver, etc.
The instrument has the characteristics of reasonable structure, convenient operation, strong flexibility, high precision, small repetition error and accurate test data.
