Description
Technical field
The present invention relates to a kind of gas engine lubricating oil composition, especially a kind of high grey type oilfield associated gas engine lubricating oil composition.
Background technology
In environmental protection, the harshness day by day of environmental regulation, to carbon monoxide (CO), the control overflow of hydrocarbon polymer (CH) and particulate emission, has expedited the emergence of portable diesel motor and has used Sweet natural gas as fuel substitute.
In the energy, in face of world energy sources famine, natural gas source is extremely abundant, and subsequent machining cost is extremely low, makes Sweet natural gas become one of best substitute of diesel oil.
Aspect at the scene, oil field operation is at field, wilderness or marine beach, and diesel oil fuel transports difficultly time-consuming, and a lot of oil well inherently has association source of the gas, is desirable alternative fuel.
In other side, domesticly widely popularize biogas technology, methane quantity surplus makes it the source of the ideal becoming marsh gas power generation.
Gas engine because its temperature of combustion is high, do not possess certain lubrication, various combustion gases mass discrepancy large (especially sulphur content is different), air-fuel mixture burning (referring to dual-fuel engine), the wearing and tearing of valve system etc. the feature that diesel oil itself possesses, the requirement of engine lubrication is just proposed and the requirement using diesel oil fuel different.As better antioxidant property, stronger detergent-dispersant performance energy, outstanding valve system wear resistance and suitable ash requirements etc.
