6、 for primary degasification from gas-bearing drilling fluid in the process of drilling. 2. PrincipleThe gas-bearing drilling fluid from throttling manifold flows into decompression tank through incoming-stream manifold of separator, then enters the separating tank through output pipe; The gas-bearin

7、g drilling fluid dashes on a series of baffles, it makes the bubbles in drilling fluid break up. And when the drilling fluid flows through the surface of baffles, it becomes turbulence to enable the gas separate from it. The bubbles are kept on the surface of baffles and inflate and break up.3. Feat

8、uresYQF-8000/1.5 liquid-gas separator has following advantages: adjustable support height, easy installation and maintenance, little spare parts, reliable performance, high quality and cheap.4. StructureYQF-8000/1.5 liquid-gas separator mainly consists of base, stand type adjustable supporting, sepa

11、t of pipe manifold）6. Installation 6.1 Install and fix separator on the special base or hard and horizontal ground. To keep it stable, tighten it by ropes whose ends are inserted into ground.6.2 In order to reduce the frictional resistance the min. internal diameter of exhaust manifold should be no

12、less than 200mm.6.3 Fixation is necessary while install pipe manifold. Connection of pipes should strictly accord with the installation drawings. 7. Operation 7.1 Operate and manage the separator according to Safely operating instruction of pressure container.7.2 Observe the pressure indication of t

13、he pressure meter when the separator works. When the pressure in the separating tank is higher than 1.55Mpa, the safety valve will open automatically to discharge air and decompress.7.3 Every time after the separator is used, close the valve between incoming-stream pipe and throttling manifold, and

14、open the drain valve to let the rest mud out.8.Maintenance and Cautions8.1 Open the screw plug for sand discharge in the manifold side to remove sand when the mud discharge manifold is blocked.8.2 The separator assembly is pressure container, so it must be used in designed working pressure and surro

15、undings. Overpressure work is forbidden. The safety valve should be checked at least once a year.8.3 The baffle should be checked after a well has been completed. Replace it if there is something wrong.8.4 Welding on the separator assembly is forbidden.8.5 The exhaust pipe and liquid discharge pipe should be arranged separately when the separator is paralleled. Uniting the pipes is forbidden.9.Photos【精品文档】第 5 页
