超稠油开发降本增效是一项系统工程,除了掺稀之外,优化注汽、技术创新、管理挖潜也是利器。“累计产油1946万吨,动用稠油区块难动用地质储量2.62亿吨。”这是西北油田塔河采油二厂2001年以来,对350余口超稠油井采用以掺稀降黏为主要手段的开采方式所取得的成果。至此,塔采二厂解决了深层碳酸盐岩溶缝洞型复合油藏稠油开采的世界性难题。 It is a systematic project to reduce the cost and increase the efficiency of super heavy oil. In addition to sparse blending, optimizing steam injection, technological innovation and management to tap the potential is also a weapon. “Accumulative production of oil 19460000 tons, the use of heavy oil blocks hard to use geological reserves of 262000000. ” This is Northwest Oilfield Tahe Oil Production Plant since 2001, more than 350 ultra-heavy oil wells to dilute viscosity As the main means of exploitation of the results achieved. At this point, TACC II solved the worldwide problem of heavy oil recovery in deep carbonate fractured-cavity composite reservoirs.
