| 摘 要： | 塔河4区奥陶系油藏是以发育大规模溶洞为主的碳酸盐岩缝洞型油藏,2005年开展注水开发以来,稳定见效期5-6年。2011年开始注水效果变差,注采井组水窜严重,递减明显加大。本文针对注水效果变差的现状,从周期注水机理入手,总结了周期注水参数优化、不同缝洞及注采连通关系周期注水方法,周期注水有效改善了区块开发效果。

| Abstract: | Ordovician reservoirs in 4th district of Tahe was carbonate fractured-vuggy reservoir mainly developed massive cave. Since the water injection from 2005, stable effect period was 5-6 years. The water injection effect began to deteriorate from 2011, water breakthrough of injection and production wells group was serious, and diminishing significantly increased. According to the situation of variation effect of water injection, this paper from the cycle water injection mechanism to sum up the cycle water injection parameter optimization, different fractured and injection connectivity relationship cycle water injection methods. The cycle water injection effectively improves the block development results. |
