The commonly used heavy oil viscosity models are just for low water cut stage, but they have some limitations when the viscosity of other oil samples is calculated in high water cut stage, this paper presents a new and simple method in high water cut stage to predict the viscosity of heavy oil, which can measure the viscosity of heavy oil by the temperature under the condition of different water cut. Compared with the commonly used model, the new model has the small computation error and can be tested in practices in calculating the viscosity of similar oilfields in high water cut stage. 相似文献

The basic physicochemical indexes of M-10-D2(m) engine oil change much less intensively in a gas engine than in a diesel. Low accumulation of elements-indicators of parts
wear-and fouling of parts by carbon and varnish deposits were noted. Formation of ash deposits in the valves was more important.
Dithiophosphate additives were depleted similarly in both engines. Information on the requirements for special oils for gas
engines is reported
