摘　　要：为改善曙光油田杜84块馆陶油藏SAGD开发效果,避免蒸汽腔快速上升造成的顶水下泄风险,达到降低开采成本、合理高效开发的目的,开展了SAGP(注N2辅助SAGD开发)技术攻关与研究。应用数值模拟以及物理模拟方法对SAGP开发过程中N2的注入方式、注入位置、段塞尺寸、以及N2/蒸汽比等重要参数进行优化设计研究。现场实施后,蒸汽腔上升减缓,井组生产效果显著提高。进一步证明SAGP开采方式能够提高顶水油藏的开采效果及经济效益,对于SAGD试验的成功以及高效开发馆陶组油藏具有现实价值和长远意义。To prevent the top water from flowing down as the steam chamber rises rapidly,the SAGP( with assisted nitrogen injection) technique is studied for Guantao oil reservoir in Block Du84,aiming to achieve reasonable and efficient development at lower exploitation cost. Numerical simulation and physical simulation are used to optimize some important parameters,such as N2 injection mode,injection point,slug size,and N2 / steam. Field application shows that the rising of steam chamber is slowed down and the performance of the well group is improved remarkably. It further proofs that SAGP can improve the recovery and economic benefit of top water reservoir,and plays a realistic and profound role in achieving successful SAGD experiment and efficient development of Guantao reservoir.
