轮南油田是塔里木盆地最早投入开发的百万吨级油田 ,已进入中高含水采油阶段 ,急需为油田实现稳产 8～ 10a目标确立稳产技术。利用精细油藏描述等技术对油田三大类潜力类型进行分析 ,确立了以水平井为主进行调整挖潜的稳产配套技术。通过稳产技术攻关与实践 ,基本肯定了确保轮南油田稳产的支撑技术是水平井技术、滚动勘探开发技术、注采系统综合调整技术和分阶段优化井网接替式稳产技术。这些技术在油田实践中便于操作 ,应用效果显著 ,使轮南油田 3a新增可采储量 12 5× 10 4t ,生产原油近 90× 10 4t。图 3参 3
Lunnan Oilfield is the earliest developed and million-ton oilfield in the Tarim Basin. It has entered the stage of middle-high water cut and oil recovery and urgently needs to establish a stable production technology for achieving a stable output of 8-10 years in the oilfield. By means of fine reservoir description and other technologies, the potential types of the three major types of oilfields are analyzed, and a stable production matching technology is established, which is mainly horizontal wells. Through the research and practice of stable production technology, it is basically confirmed that the supporting technologies to ensure stable production of Lunnan Oilfield are horizontal well technology, rolling exploration and development technology, comprehensive adjustment technology of injection and production systems, and stable production technology of well replacement in phases. These technologies are easy to operate in oil field practice and have obvious application effects. The newly-added recoverable reserves of Dunan Oilfield 3a is 125 × 10 4t and the production of crude oil is nearly 90 × 10 4t. Figure 3 Reference 3
