XinJiang oilfield is located in the Northwest of China, in which large oil reserves have been discovered in reservoirs with very low permeability (<14×10 -3 μm 2 ). These reservoirs are featured with light oil in moderate depth, high reservoir pressure, but relatively low reservoir temperature (65~78 o C) and low oil viscosity (<10mPa•s). Primary production and limited water flooding experience have shown that the recovery factor in these reservoirs is very low due to lack of reservoir energy and poor water injectivity. Gas injection has been optioned as an alternative secondary or tertiary technique to maintain reservoir pressure and/or increase sweeping and displacement efficiency. In this study, the feasibility of air injection via a low temperature oxidation (LTO) process has been studied. Laboratory experiments were focused on LTO characteristics of oil samples at low temperature range and core flooding using air at various reservoir conditions. Reservoir simulation studies were conducted in order to predict the reservoir performance under the air injection scheme and to optimize the operational parameters. The oxygen consumption rates at reservoir temperature and IOR potentials at different reservoir conditions were assessed for a number of selected reservoirs in the region. A pilot project has been designed based on experimental data, reservoir simulation results and field experience of air injection gained in other regions of China. Issues related to safety and corrosion control during air injection and the project economics were also addressed in the paper.

In order to improve the management level of China's state-owned enterprises, we should consider the management environment of state-owned enterprises and construct a suitable management mode, instead of copying the management experiences in western countries. Based on an in-depth analysis, this paper puts forward suggestions for the management reform in state-owned enterprises from three aspects. How to properly deal with the relationship between management reform and experience inheritance in state-owned enterprises, how to integrate China's local cultures, and how to reflect the the theme of the times are the key points to construct the suitable management mode for state-owned enterprises.
The harmonious development of China state-owned enterprise and employees is the essential approach to develop state-owned enterprise. The development of enterprise is the premise of employees' developments, and only harmonious enterprise can ensure employees' complete development and bring up better employees. At the same time, employee's quality decides the development level of enterprise, and employee's survival and complete development are the bases for the harmonious development of enterprise. In this article, we study the employee training for China state-owned enterprises based on harmony concept, and further discuss the harmonious development between enterprise and employees. The contents of the article include the comprehension of harmony concept in the development of China state-owned enterprise, the main contents and the main modes of employee training embodying harmony in the principal of employee training, which can offer primary theoretic base and implementation frame for the work of employee training, and possess the function of reference for the employee training of state-owned enterprise.
