Research On Electric Heating Rod Pumping Well Process Design And Application On Niu Xintuo Oil Field

Along with the penetration of field development, the exploitation proportion of some macro viscosities, high solidification point and high waxy crude are bigger. To develop these oil deposits to use craft chemistry, note steam and so on, exists the problem of costs high and difficulty of field conducting. For the sake of developing these reservoir economically and efficiently,in view of short in flowability and high in sensitivity to temperature of heavy oil,useing the electric heating oil extraction rod mining technology to coordinate other crafts can be able to adapt the thick oil deposit development well. The temperature is the main cause to affect the viscosity of the primary,Therefore, it is very important to establish the well chamber temperature to distribute. The viscosity is appraises the thick oil characteristic the core parameter, specially in the oil field exploration stage and the development initial period, the viscosity material often limits in or several temperatures lights, lacks needs the temperature (for example formation temperature and so on) under viscometer data. This article with a well chamber temperature field model, has calculated under the conventional well chamber temperature distribution, simultaneously has calculated the well chamber viscosity distribution through the temperature distribution. According to actual needs, this article has carried on the example of calculation and analysis, in order to explain the practicability and operability of wellbore temperature field model. This article also consulted beef heart tuo oilfield using electric heating sucker obtained the actual benefit, is also very good to have proved that the electric heating technology advantage and value.
