Gathering Process Technology Research Of Dabei Block In Crassus Field

Tarim Basin in Xinjiang is rich in natural gas reserves.In recent years,the Tarim Oilfield Company continuously intensify the development of natural gas resources,there are always new breakthroughs especially in the exploration and development work of Crassus gas field.Great Northern block is one of the four blocks of Crassus gas field,which is located in the middle of the south of the Tianshan Mountains.And it is located within Baicheng County,Aksu Prefecture,Xinjiang territory.The project is based on the overall field development and deployment of Tarim Oilfield Company on the Great Northern,to research the Great Northern gas internal gathering.And recommend a high security and features suitable and mature technology building program by comparing the technical and economic and social impact analysis.Simultaneously,determine the internal gathering and processing plant engineering and investment,to provide a reliable scientific basis for the relevant departments on the surface construction decisions of the Great Northern gas.The block of the overall development of the Great Northern Crassus field spend 1,101 Great Northern,Great Northern 2,201 Great Northern,Great Northern Block 3,etc.And Deployment of production wells 32(where 24 new wells,the use of old wells 8).With the overall deployment,the implementation of priority,yielding a single well,well indirectly for rolling development model development.The natural gas gathering using two cloth station mode,single-wel and multi-well gas-phase binding,continuous measurement of single-well multiwell combination of rotation.And each wellsite gas gathering station gas-liquid multiphase to gas processing plant in Great Northern.The raw gas using the J-T valve throttling refrigeration and the producted natural gas transmission to round the southern gas gathering station after filling glycol dehydration dealkylation process.And the separated gas to Dawanqi sewage treatment after reinjection operation area.The oil and gas gathering system new wellsite 27,Block 2 gas gathering stations,gas gathering regional seat valve chamber 2.And reform on gas gathering station that has been built(the great northern gas station test collection)and 3 wellsite(DB201、DB202、DB2).New gas gathering trunk 17.5km,gas production pipeline 41 km,fuel gas pipelines 52.6km.Gas gathering lines and gas production pipelines are made of 316 L double metal composite pipe lining,Site selection of duplex stainless steel pipe(22Cr).
