¡¡¡¡Ground Control
During the cause of test, fluid should be controlla-bly guided into separator and burner after flowingthrough drilling rod or tubing, the assembly is named ascontrol assembly, which can control the pressure andflow-rate of the fluid safely and effectively.
Ò»¡¢ Control Head
Jointed with the upper of the test string, control headis classified into rotary head and un-rotary head of twokinds, and also into three kinds of 35MPa, 70MPa and105MPa according to the bearing pressure, and it canlet the high-pressure fluid flow out of string, but alsopump fluid into well.
¶þ¡¢ Rigid manifold
Used to control fluid pressure and flow-rate, rigidmanifold is jointed with control head upwards and con-nected with separator and blowout pipeline downwards.
The working pressure includes 35MPa, 70Ma and105MPa with appropriate test pressure of 70MPa,105Ma and 140MPa.
Èý¡¢ Active manifold
Used to joint the control head, rigid manifold andblowout pipeline, the manifold consists of special EUEseamless steel pipeline union and active elbow.
The working pressure includes 35MPa, 70Ma and105MPa with appropriate test pressure of 70MPa,105Ma and 140MPa.
The manifold should be regularly inspected andlubricated, sealing ring should be replaced and sealingtested to ensure safety in test.
