Mud Gas Separator is commonly called a gas-buster or poor boy degasser. It captures and separates large volume of free gas within the drilling fluid. If there is a "KICK" situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates. The gas then is forced to flow through a line and vent it to a flare. A "KICK" situation happens when the annular hydrostatic pressure in a drilling well temporarily (and usually relatively suddenly) falls below that of the formation, or pore, pressure in a permeable section downhole, and before control of the situation is lost. It is always safe to design the mud/gas separator that will handle the maximum possible gas flow that can occur.〔Dilling Fluids Processing Handbook ISBN 0-7506-7775-9〕〔Mud Equipment Manual ISBN 0-87201-614-5〕 ==Types of Mud/Gas Separators== The principle of mud/gas separation for different types of vessels is the same.〔SPE Drilling Engineering, December 1991〕 * Closed bottom type * Open bottom type * Float type The closed-bottom separator, as the name implies, is closed at the vessel bottom with the mud return line directed back to the mud tanks. Commonly called the poor boy, the open-bottom mud gas separator is typically mounted on a mud tank or trip tank with the bottom of the separator body submerged in the mud. Fluid level (mud leg) is maintained in a float-type mud gas separator by a float/valve configuration. The float opens and closes a valve on the mud return line to maintain the mud-leg level. According to pedestal or base type there are * Fixed type * Elevating type Poor boy degasser in China is usually named according to vessel diameter.So the type also including * FLQ800 or ZYQ800 * FLQ1000 * FLQ1200 * FLQ1400 Usually, the degasser type or configuration is customizable 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mud Gas Separator」の詳細全文を読む スポンサード リンク
