| Abstract: |
| The new efficient quantitative degasser used the design of quantitative pump, electric heater, degassing tank and vacuum pump, can quantitatively collect mud, heat mud, stir mud with a high speed, and suck mud in negative pressure. In addition, it contains temperature control system and data acquisition test system, realizes the mud analysis of oil and gas online. Meanwhile, the degasser was designed in accordance with the well field of explosion-proof, and the level of explosion-proof can reach grade 1. The results show that the rate of sample mud for the new efficient quantitative degasser is half a liter per minute, and C1-C8, benzene, toluene and so on gas composition can be degassed by it. Also, the degassing efficiency of the new efficient quantitative degasser is about fifty percent, which is 6-10 times higher than the degassing efficiency of electric degasser under the same environment. The performance of new efficient quantitative degasser is reliable and stable, and the degassing efficiency is much higher than electric degasser 's under the same environment. |
