The effect of tribology factors on bearing vibration is studied experimentally. AR model and WPT are used to processing the normal arid abnormal signals. The results are as follows:1. The vibration of ball bearings is caused by the tribology action of contact pairs of ball and ring races and has the essential of tribo-dynamics. Any factors affecting the tribology characteristics of contact pairs will affect vibration and noise of bearings consequently.2. Vibration characteristics of bearing keep almostly unchanged with the increasing of axial load expecting the increasing of nature frequencies. When radial load increasing with axial load unchanged, nature frequencies keep unchanged but some new vibration peaks appears in the spectrum.3. Vibration amplitudes are damped and nature frequency are enhanced with sufficient lubrication. Vibration and noise of bearings increase obviously and roar can happen and the contact surfaces scratch slightly under insufficient and unclean lubrication state. Bearing will be disabled in a few minutes without any lubrication.4. Bearing vibration is unstable under low speed. With the speed increasing, the vibration become stable and natural frequencies increase slightly but the amplitudes increase apparently.5. Bearing vibration can be excited only by some harmonics ofwaviness without lubrication and by all harmonics with lubrication based on the theoretical analysis.6. The nature frequencies of ball bearings decrease with the increasing sizes. When international clearance increasing, nature frequencies decrease in radial and increase in axial and angular and the amplitudes increase in radial and decrease in axial and angular. When the number of balls increasing, nature frequencies increase and amplitudes decrease. When the pitch diameter increasing, axial nature frequency increase and others nearly keep no change. When outer race groove curvature radius increasing, nature frequencies increase in radial and decrease in axial and angular and amplitudes keep no change in radial and increase in axial and angular. When inner race groove curvature radius increasing, nature frequencies decrease and amplitudes increase.7. The distortion in amplitude and frequency components of bearing vibration signals picked up by the present probe measurement method is founded and right conclusions cannot be achieved by the signals. When accelerometer is rigidly screwed with steel stud onto a flat outer surface of a ball bearing, vibration signal can be got without distortion and the reliability of research on bearing vibration is assured.8. AR model is suitable for large samples of bearing vibration signals, square root of length of samples can be used as the upper limitation of order determination and the FPE order selection criterion is effective. Many advantages of AR spectrum are founded over the classical based on FFT.9. Time-Frequency analysis is necessary for abnormal noise of ball bearings. WPT overcomes the principle shortcomings of STFT and proved to be a best tool to process the abnormal signals.

This study analysised the condition of Xinjiang's petroleum resource and made an evaluation and it points out that the development of petroleum and natural gas of Xinjiang is still in the developing period in which it aims at discovering the petrol field and increasing its reserves.Although it has a great exploring potential,because of its geograghy limitation and a lack of exploring funds,the exploring level is till low,even lower than the everage level of the whole country. The study is based on theories of industry distributions,its concentration,macroscopic analysis,government regulations and continuing development.From microcosmic and macroscopic aspects,it scientifically and systematically analyses the problems in the development of petroleum industry in Xinjiang.It points that the developments of middle and upper reaches lack a balance and have no rational industry structures.So it is hard to form an integral industry chains.Moreover,the upper reach covers a too much large proportion in the development,so it can not give a strong impetus to other industries.Based it,the paper points the industrial concentration of Petroleum Chemical Products Manufacture of Xinjiang should be enhanced and Input to Petroleum Chemical Products Manufacture of Xinjiang should be increased.Due to a lack of an established fair and competitive market and government's perfect laws and regulations on petroleum industry,it points that the phenomenon of mixed operation has become common in monolopied business and competitive business,so the systems of petroleum industry needs to be restructured.It states clearly that the country should take the development and benefits of Xinjiang's economy into consideration when making strategies for petroleum development .Besides,the allocation of profits between the center and the local should be well arranged so that we can guarantee the profits of Xinjiang ,considered as a resource area.It also reveals that we should not only overcome limitations of resources,environment,economy and technology on continuring development,but also we should deal with some realistic problems well.For instance,contradictions between the concept of limited resource and continuing development,the relationship between petroleum industry's own features and continuing development,the contradictions between the limits on supply of petroleum and the need of future development of continuing resource ,outdated petroleum technology and the need of advanced technology for continuing development,tremendous damages to environment and requirements of environment protection for continuing development and Xinjiang continuing economic development,outdated policy of industry and continuing development,the relationship between continuing development of Xinjiang petroleum industry and continuing economic development of Xinjiang.

本研究以产业布局理论、产业集中度理论、灰关联分析理论、政府规制理论、可持续发展理论为依据，从微观、宏观两个层面，科学、系统、全面地分析新疆石油产业的发展问题，指出：新疆石油天然气目前仍处于油气田发现和增储的主要发展阶段，开发潜力巨大，但由于地质原因及勘探投入的不足，石油天然气探明程度偏低，低于全国平均水平；新疆石油产业产业结构布局不合理、上中下游发展不平衡，难以形成完整的产业链条，对工业的带动力与其本身具有的经济总量很不匹配；新疆石油开采业和石油加工业属于高度寡头垄断的市场类型，新疆石油化工业属于竞争型的市场结构，要想石油产业对新疆经济有较强的带动作用，新疆石油化工业必须上升到一定的层次和规模，在提高规模的基础上，提高新疆化工业的产业集中度；新疆石油加工业和化工业与农业呈现较高的关联度，加大对石油加工业和化工业的投入，对新疆经济的协调发展有着深远的影响；政府要从石油产业本质特征和发展趋势为着眼点，实施规制改革，分开政府规制政策的制定部门和监管部门职能，建立健全石油产业法律法规体系，对垄断性业务和竞争性业务实施分类规制；国家石油发展战略的制定应兼顾新疆区域经济的发展和利益，应切实处理好新疆与中央的利益分配，切实保证新疆作为资源产区合理的资源收益；新疆石油产业要想得以可持续发展，不仅要克服影响可持续发展的资源、环境、经济和技术等客观因素，还要处理好观念、需求、政策等诸多主观因素。

The geology research of carbonate reservoirs in Ordovician of Tahe oilfield showed that many large dissolved vugs and fractures were developed. The spread of the reservoir take on a very heterogeneous state. And the typical fractured-vuggy reservoirs was formed. According to the combination of the various spaces, the formation was divided into vuggy formation, fractured-vuggy formation and fractured formation. The research showed that development of the vug is relevant to the its position on the structure, the fractures, the water surface and the weathering surface. Multi-phase charge and recharge of the oil in the reservoirs resulted in the complexity of the fluid distribution. So the"Bottle Model"was brought forward to explain the movement of the water-oil contact. The special storage space and the complex fluid distribution lead to the unstability of the production and the complexity of the water cut. In order to explain the characteristic of the fracture-vug unit was brought forward and the basic principle and method of the partition of the fracture-vug unit was formed. The classification and evaluation of the units were performed according the reserve and energy. Based on the research of geology characteristic and the fluid flow in the reservoir the comprehensive numerical simulation plan of the fractured-vuggy reservoirs were established. Through the selection of the simulation unit, fluid flow type and parameter equivalent the triple media reservoir simulation model was established. Considering the practical application the model was resolved by the DKR decomposition conjugate grads method. Based on the fine reservoir description of Dsitrict IV of the Tahe oilfield the various space type were classified and combined together. The geology model of Unit S48 was constructed. Two typical single well model was established according to the geology and the dynamic phenomena. Finally the single well model and the Unit S48 were simulated by the triple media reservoir simulator. Via the local grid refinement and coarsening in the simulation good matchs were gained. Based on the results of the simulation the reserve distribution, percent of reserve produced in various space and the natural energy were analyzed. The fluid was storaged in the fractures and vugs mostly and more than 90% the produced oil came from the systems. The energy belonged to the active one. The results of simulation accorded with the fact and showed the validity and practicability the research and the simulator.
