In order to ensure the safety of high pour-point oil pipeline transportation, transportation process generally uses heat insulation transportation, skin effect transportation and oil modified transportation. For pipe is located in turbulent areas, the traditional single mode does not meet the requirements of high pour-point oil pipeline safety transportation, combined with the advantages of heat insulation transportation and skin effect transportation, provided a mixed transmission process which is the combination of heat insulation transporta-tion and skin effect transportation. Take crude oil transmission pipeline of Lake Albert as an example,the driving way of long- distance pipeline contains external electric driven,natural gas power generation driven, crude oil or diesel engine driven. Heat source includes natural gas, crude oil or diesel oil heating furnace. The pipeline by the area should has higher envi-ronmental requirement, if use the crude oil in the pipeline as a source of power and heat source, maybe cannot get the approval of the local government, so choose diesel is relatively feasible scheme.

This article analyses the characteristics and the difference of production process and the wellbore fluid temperature state of geothermal production Wells and oil production Wells,to characteristics of formation temperature and heat conduction of geothermal well,basing on the basic theory of fluid mechanics and heat transfer,a steady state model of shaft axial temperature distribution,according with the characteristics of geothermal well,has been established.Through this model,and combined with the actual data in the producing process of A well,the fluid temperature distribution characteristics inside the production tubing string under steady state is analyzed,according to the analysis results:results calculated through the model with the variable of geothermal gradient is more in line with the actual production,by optimizing the production capacity and pump pipe insulation layer thickness,the producing fluid temperature can be effectively improved.

Due to development of shale gas start late in China ,feasibility evaluation of shale gas development in theoretical research have not carried out at home and abroad .There is a urgent need to develop theory and method of the feasibility of the formation of a shale gas reservoir to achieve the scientific purpose of the rapid development of shale gas reservoirs .In this paper ,starting from shale gas geological characteristics and development characteristics and contrasting shale gas reservoir at home and abroad .using fuzzy AHP to establish shale gas development multifactor rapid assessment theory and methods .The critical factors affecting the development of shale gas are filtered out .The results show that the multi-factor evaluation model based on fuzzy analytic hierarchy process for the evaluation of the feasibility of shale gas development is feasible ,shale gas reservoir development a favorable area screening guiding role .

原油管线一般采用加热方式输油.管线运行一段时期后,管道外防腐绝缘层会逐年老化,影响管线正常运行,因此需要有计划地安排防腐层大修.大修时,热油管线与土壤建立的稳定温度场遭到破坏,为了保证管线安全生产运行,常常需要对管线周围土壤温度场进行测量.以便监测管道内原油温度的变化.在本文中,详细查阅了大量有关热电偶和土壤温度场的资料,掌握了热电偶测温原理及测温方法,并在实践中进行应用.通过查阅前人关于土壤温度场的研究,对管道周围土壤温度的分布情况有了较为深刻的理解和认识,并分析了采用热电偶测温装置测得的土壤、大气温度数据,得到了管道周围土壤温度场分布的一般规律及其影响因素.
