Ground Technology Research In Jiyuan Oilfield

ChangQing oilfield has created the AnSai oilfield, JingAn oilfield and XiFeng oilfieldmode which have been referenced for JIYUAN area in initial stage of development. JIYUANoilfield has complex terrain and decentralized blocks, especially with the multiple zonecomposite rolling development and produced water not compatible in different series strata,thus the mode of JIYUAN oilfield ground technology has been created through absorptiveutilization and innovative development.This paper summarizes a large number of accumulated exploitation and constructionexperience in JIYUAN oilfield; verifies and revises a series of correlation techniques inpractical application which including well group development, type Y process model,skid-mounted integration, associated gas utilization and digital management; contrasts andanalysis the economic efficiency of above related technical. Integrates the actualcharacteristics of the JIYUAN oilfield, it forms six new innovative technologies and eightsupporting technologies.The article takes thorough and detailed analysis on the process of technical integratedinnovation, optimization and integration of technological process, vigorously promoted thefour modernization’s construction, realized comprehensive utilization of resources. Whichproposing a new ground technologies and techniques with “single、double、three、more andgroup” mode as the core characteristics in JIYUAN oilfield, creating a new mode withdistinctive feature of JIYUAN ground construction, achieving the social economic andecological benefit simultaneously and further promoted the ground construction level ofJIYUAN oilfield. All of these achievements play a leading and exemplary role in the wholefield.
