中国海油非常规气勘探开发一体化探索与成效

美国页岩油气革命带来非常规油气工业快速发展,中国海洋石油集团有限公司(简称中国海油)顺势而为,积极开拓非常规油气业务。中国海油收购中联煤层气公司以后,面对煤层气资源品位差、储量丰度低、产量规模低、建产能力低,以及致密气有储量、少产量等困境,结合煤层气、致密气气藏特点和勘探开发技术要求,通过勘探开发一体化的管理创新,探索如何实现非常规气商业性开采的路径,并取得了初步成效。通过管理方式与制度建设创新,改变了非常规气勘探开发节奏和成效,实现了当年从勘探钻井、到管网建设、再到试产销售的目标,大幅缩短了生产周期,不仅改善了勘探质量和投资效率,而且避免了直接规模开发的风险,加速了增储上产的步伐。希望通过点上的探索示范和相应的制度改革创新,撬动中国非常规气产业的健康有序发展。

Exploration and effect of exploration and development integration in unconventional gas of CNOOC

The shale oil and gas revolution in the United States has brought about the rapid development of unconventional oil and gas industry.China National Offshore Oil Corporation(hereinafter referred to as CNOOC)follows the trend and actively opens up the unconventional oil and gas business.After acquired China United Coalbed Methane Company,CNOOC was faced with a series of challenges in unconventional gas development.For coalbed methane,resource grade is poor,reserve abundance is low,production scale is small and capacity of productivity construction is poor.For tight gas,the reserves are present but the production is low.Combined with the characteristics of coalbed methane and tight gas reservoirs and the technical requirements of exploration and development,through the management innovation of exploration and development integration,CNOOC has explored the path to achieve commercial development of unconventional gas and achieved preliminary results.Through the innovation of management mode and system construction,the rhythm and effect of unconventional gas exploration and development have been obtained,which realize the goal of exploration and drilling,pipeline construction,pilot production and gas sales in the same year,and greatly shortened the production cycle.It not only improves the exploration quality and investment effi ciency,but also avoids the risk of direct large-scale development and accelerates the pace of increasing reserves and production.It is hoped that through the exploration and demonstration from a single project and its corresponding system reform and innovation,the healthy and orderly development of unconventional gas industry will be promoted in China.
