In order to study the effective prevention measures to improve the regulation effect of the anti-deflecting measure in Bei 301 operation area and prolong the pump cycle of the oil well. The calculation of the historical data of the eccentric wear well and the analysis of eccentric wear prevention effect show that eccentric wear condition in Bei 301 operation area of hailaer oilfield is relatively serious and the operating wells’ ratio of rod breakage and tube leakage increases year by year due to eccentric wear [1,2]. In 2014, the proportion of rod breakage and tube leakage in the operating wells of the operation area was 19.4% and 45.2% respectively, and the average pump inspection cycle was around 400 days. The reasons for the serious wear of the rod pipe in Bei 301 operation area are the improper production parameters, the submergence depth, high water content and well fluid properties according to the detailed data analysis of the pump operation. Active eccentric wear prevention measures have some effect, and next research direction for preventing eccentric wear is put forward in this paper: the paraffin-removing technology, bi-directional protected box coupling and low friction pump combined with the problems faced by the operating area.
Heat transfer process in power system applications mainly refers to the gas in the cylinder through the combustion chamber wall and related parts pass the process of cooling medium, the heat it mainly includes the gas flow and combustion in cylinder, cylinder internal boundary layer heat transfer (gas and wall heat transfer), heated component of thermal load and thermal conductivity, cooling medium heat transfer, and a series of process. Because it is closely related to the working process of the power system, the lubrication cooling system and the structural strength design of components, the heat transfer and its thermal load will directly affect the dynamic performance, economy and reliability of the system. Therefore, the heat conduction of machining in the power system has always been an important field in the power system research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
