12月3日,以元284区投产55口水平井为标志,长庆油田在华庆地区建成的中国石油第一个水平井规模开发示范区已“入库归仓”。据悉,在这个水平井井口数所占比例只有8.1%的示范区,原油产量却占示范区总产量的58.3%。作为2012年中国石油集团水平井规模开发示范区之一,负责示范区管理开发的长庆采油二处,将水平井的布井比例提高到总钻井口数的19.9%,实现了水平井开发跳跃式发展。水平井工艺技术的广泛应用推广,从根本上解决了超低渗油藏产量低、稳产难的瓶颈问题。长庆油田在华庆地区实现了
December 3, the yuan 284 area put into operation 55 horizontal wells as a symbol, built in Huaqing Changqing Oilfield, the first horizontal well scale demonstration zone has been “warehousing ”. It is learned that in this horizontal wellhead number of only 8.1% of the demonstration area, crude oil production accounted for 58.3% of the total output of the demonstration area. As one of the CNPC’s horizontal well scale development demonstration zones in 2012, Changqing Oilfield 2, which is responsible for the development and management of the demonstration zone, raised the proportion of horizontal wells in well drilling to 19.9% of the total number of wells drilled and achieved the leap-type development of horizontal wells development of. The widespread application and promotion of horizontal well technology fundamentally solves the bottleneck problem of low yield and stable production in ultra-low permeability reservoirs. Changqing Oilfield realized in Huaqing area
