中文摘要:
      针对特稠油、超稠油油藏难以实现注、采井间有效驱替,采用水平井火驱辅助重力泄油方式,通过室内物理模拟试验,研究了重力火驱开发过程点火、控火、火腔培育、生产特征、调控策略,结果表明,水平井火驱重力泄油技术有效地解决厚层、稠油直井火驱开发中火线纵向超覆的问题,大幅度提高厚层稠油油藏火驱波及效率,提高原油采收率。
英文摘要:
      Aiming at the difficulty of realizing effective displacement between injection wells and production wells in super heavy oil and extra heavy oil reservoirs, horizontal well fire drive assisted gravity drainage method,through physical simulation, the ignition, fire control, fire chamber cultivation, production characteristics and control strategy of gravity fire drive development process are studied. The results show that the horizontal well gravity drainage technology can effectively solve the problem of vertical overlap of fire line in thick and heavy oil vertical well fire drive development,and greatly improve the sweep efficiency of heavy oil reservoir and oil recovery efficiency.
