Study On New Energy Power System Of Drilling In Sulige Gas Field

In recent years,with the continuous deterioration of the atmospheric environment,environmental problems become an urgent problem to be solved.Replacing the traditional power fuel with electricity or natural gas can realize clean production,and then play a certain role in protecting the ecological environment.This paper takes the drilling power system of sugri oilfield as the research object,and the main research contents are as follows:1)introduce the advantages and disadvantages of the transformation scheme and scheme of the pure natural gas power system,the transformation scheme and scheme of the mixed fuel,the transformation scheme and scheme of replacing oil by electricity,then compare and analyze three different transformation schemes based on the actual situation of the drilling power system in sugri oilfield,and finally select the scheme of replacing oil by electricity to promote the drilling power system in Sulige oilfield Transformation;2)the transformation of electric oil substitute system in Sulige gas field is introduced concretely,and through the comparison of the transformation and introduction of the mechanical part of the drilling machine,the high-voltage electrical part and the low-voltage electrical part,the specific transformation scheme of the regional drilling power system in Sulige oilfield is finally determined,and the application of the transformation scheme in the drilling of specific oilfield and the original driving model are introduced The transformation shows relatively excellent energy conservation and emission reduction effect.3)analyze the economic and environmental protection effects of the electricity replacing oil transformation in sugri oilfield.Through analysis and comparison,it can be seen that the electricity replacing oil transformation meets the requirements of the construction site of the drilling crew,with considerable economic and social benefits.Take the 50052 drilling crew as an example,in 2013,it constructed 9 wells in Sunan block,with a drilling footage of 35756 meters.The statistical data shows that it consumes firewood 929 tons of oil,103.22 tons of diesel oil consumed by a single well,and 6.8233 million yuan of cost.According to calculation,if the electricity cost of the power grid is 4.4323 million yuan,the cost can be saved by 2.391 million yuan,and the cost control range is relatively large.Therefore,under the condition of convenient power grid,the implementation of electricity instead of oil by the drilling crew has a good promotion and practical value.
