| Drilling engineering is an important part of the development of oil and gas exploration,drilling rigs as drilling equipment,relying on i nternal combustion engines(mainly diesel)to power the rig.Yanchang Oilfield As China's first onshore oil fields,oil drilling to extend a huge amount of diesel fuel consumed annually,on the one hand,emissions of toxic gases containing CO,HC,NOx,lead,benzene and other carcinogens and manufacture a large number of pollutants and greenhouse gases caused great harm to the environment and human health,on the other hand drilling required huge diesel.Strong proponent of energy conservation in the country today,as high energy drilling industry,development and application of natural gas engine technology to achieve cost reduction targets has important significance.Through the projects demonstration,technology research and development,finance analysis,based on a large amount of data,a comprehensive analysis of the natural gas engine power project in the drilling technology is reasonable,whether it meets the demand in the market,in the economic feasibility,financial profit,and provides scientific reference for the implementation to promote the project.Natural gas drilling machine for only the United Kingdom conducted research test,no application of drilling reports and documents.Dual fuel engine is used in drilling are in the experimental stage of development.In the domestic gas replacing oil technology research and application of China Petroleum Group made several experiments,the performance of the engine can be further optimized.Therefore,we determined through innovative technology and content innovation form of R & D optimization of drilling natural gas engine.Through our team effort,has been a breakthrough in the key technology of this project,such as the power allocation of natural gas engine with different drilling rig;hydraulic coupling transmission increase,further strengthen the reliability of drilling natural gas engine as power;according to the characteristics of natural gas engine speed,the transmission ratio of transformation,to match with the original drilling accessory the consistency of the requirements of equipment,realize the power of natural gas engine matching research breakthrough.Through the power of the natural gas engine rig,research and analysis,put forward in the process of drilling for natural gas engine under shock load capacity of the said technology solutions.According to the nature of LNG,the distribution process and development of drilling well LNG supply.To capture the core technology,so as to implement the power conversion gas machine based on diesel engine,and drilling test,so as to realize the natural gas of diesel engine to replace all.This thesis mainly analyzed from the following several aspects of the project of natural gas engines mechanical rig technical rationality and economic feasibility,respectively is : the background and significance of the project;a feasibility study on the theories and methods;industry and market analysis;product development,the organization of the project management;financial management and investment benefit analysis;risk control.Through the all-round,multi-angle evaluation,we believe that Feasibility Study on natural gas engines mechanical rig items conform to the requirements of the national policy,in line with the industry development trend,in line with market demand,the project investment needs sufficient,mature technology conditions,capital source,good economic benefit and social benefit is remarkable,the project is feasible. |
