Feasibility Study On Underground Gas Storage Reservoir In Jilin Oilfield

To implement the national strategy of revitalization of the northeast old industrial base vigorously promoting clean energy in primary energy consumption ratio,to meet the demand for natural gas in northeast China as soon as possible,improve the northeast pipeline by the gas transmission capacity of the pipeline,to adapt to the target user gas market fluctuation,and needs to be supporting the construction of underground gas storage for seasonal peak shaving.And in order to better ensure the northeast emergency gas supply pipeline accident situation;Jilin oil field gas storage project feasibility study for scientific,reasonable,safe and efficient use of natural gas,alleviate the increasingly tense energy demand,has the very vital significance.This article through to the double lump of a commentary on gas storage station(double tuo on gas storage station),15 wellsite(tuo 118-2,2,tuo tuo 126-29,tuo A4-4,a total of four cluster well site;tuo library H2 ~ H11-1,a total of 11 high Angle single-well wellsite),the old two old well site(tuo,tuo A4-4,103-1),and between all the wellsite construction of form a complete set and wellsite to glosses station of the pipeline and before the big points to glosses stand 20 km two-way pipeline note collection and process system and utility system process feasibility analysis [2],by using the methods of feasibility scheme comparison,determine the size of the injection-production system of underground gas storage,gas injection period to190 days,gas recovery period to 150 days,pressure balance need to 25 days;Note antifreeze technology on wellhead,alcohol injection system is set in well site,as well open early anti-freeze measures;Gas injection process to choose three single capacity is 100 x 104 m3 /d electric displacement reciprocating compressor unit,gas injection inlet pressure in 3.0 5.0MPa,outlet pressure is 7.0-25 MPa;Dew point control scheme comparison process only for dehydration process,determine the teg dehydration process,set up a set of 450 x 104 m3 / d teg dehydration device;Standing outside the gathering system process flow,plan optimization of utility system,equipment type selection;Through analyzing the adaptability of underground gas storage project,determine the project has good economic value and social value,have a certain ability to resist risk,and determine the jilin oil field gas storage project is feasible.
