The gathering system for peripheral pattern in oil field, some wells must be shutdown because of the high backpressure of well, which due to the influence of pipe deformation, blockage, wax precipitation, water volume, crude oil physical property, scale deposit and so on. There in no report about the diagnosis method of reason for high backpressure. This paper defined the wells position in the peripheral pattern by means of the diagnosis method that is node point pressure-temperature method. It can judge if there is block up in pipeline by pressure drop per hectometer of water, and also if the designed pipe standard can match the operating conditions. The diagnose methods proposed can make sure the reasons of well high backpressure, then, the resolve schemes can be obtained. © (2013) Trans Tech Publications, Switzerland. Source

The world and China's energy situation and the building energy consumption is been summarized and analyzed. On the basis of the characteristics of our climate and building energy consumption, the building energy consumption gap between China and developed countries is contrasted. By contrast, building energy conservation in China is reiterated to be of great significance. Building energy conservation targets and the measures taken in China are concluded and building energy conservation plan in the Twelfth Five-year Plan period is summarized. © (2012) Trans Tech Publications, Switzerland.

In order to reduce energy consumption, solve the rural house of low energy consumption, integrated system is imperative under the situation of the new technology is applied to the villages and towns in energy conservation and emission reduction can therefore play a big role. This paper puts forward in the northeast area the heated kang facilities, the solar energy and methane integration, this paper introduces the integrated system design part, draw the system design, and the system's working principle and features a detailed explanation. © (2013) Trans Tech Publications, Switzerland.

In this paper, ways of heat transfer through windows and doors between the indoor and outdoor environment in the northern area are summarized. And every heat transfer way is described by mathematical formula. On this basis, methods to improve the energy saving performance of exterior windows are put forward according to factors affecting heat transfer through windows. The first method is increasing solar radiation heat, and then reducing heat loss by infiltration, and increasing the thermal resistance as much as possible. Ideal form of energy-saving window is proposed based on compared windows with different material and thermal resistance. © (2014) Trans Tech Publications, Switzerland. Source

Influences of void ratio of glass fiber cloth, conductivity of glass fiber cloth, number of of insulation layer and emissivity of aluminium foil on apparent heat conductivity of vacuum heat insulation oil pipe are calculated based on the experiment plat in master machinery plant of Liaohe Petroleum Exploration Bureau. The results show that apparent heat conductivity of vacuum heat insulation oil pipe is inverse ratio to void ratio of glass fiber cloth, and is proportional to conductivity of glass fiber cloth and emissivity of aluminium foil. At vacuum condition, 6 layers is appropriate. © (2013) Trans Tech Publications, Switzerland. Source
