姬塬油田黄36长8油藏属低渗透岩性油藏,目前处于开发初期,但油藏含水高,水窜问题突出。针对黄36长8油藏的水淹现状,从储层的非均质性、注采井网与地应力的适应性、油层初期改造、天然裂缝与人工裂缝的影响等方面进行了综合研究,找到了黄36区长8油藏水驱低效开发的问题所在,结合研究提出了改善水驱开发效果的对策和建议,指导下步开发调整。
Jiuyuan Oilfield Huang 36 Chang 8 reservoir is a low permeability lithologic reservoir, which is currently in the early stage of development. However, the reservoirs have high water content and prominent water channeling problems. According to the status quo of water flooding in Chang-36 reservoir of Huang-36, a comprehensive study was carried out on the aspects of reservoir heterogeneity, adaptability of well-logging and grouting, in-situ stress, initial alteration of oil reservoirs, natural fractures and artificial fractures. The problem of low efficient water flooding development in Huang36 Wizhang8 reservoir was found. Combining with the research, some countermeasures and suggestions to improve the effect of water flooding development were put forward to guide the further development and adjustment.
