摘要
加拿大阿尔伯达盆地油砂资源丰富,蒸汽辅助重力泄油(SAGD,Steam Assisted Gravity Drainage)技术为油砂开发中成熟且广泛应用的原地开发技术。基于SAGD开发技术下的油砂开发动用储量的正确评估是油砂SAGD开发方案制定和合理开发指标预测的基础。在考虑构造、储层及开发井网部署的条件下,结合油砂开发过程中的关键影响因素,提出了油砂开发动用储量评估方法,从总地质储量、SAGD技术可开发地质储量和SAGD开发动用地质储量3个层面实现油砂储量的综合评价。
Abundant oil sand resource has been found in the Albert Basin of Canada and the Steam Assisted Gravity Drainage(SAGD)is a matured and widely adopted technology for oilsand development.The logical and rational assessment of exploitable bitumen volume in place is an essential foundation for designing the oil sand development plan by SAGD.The methods of apprising the exploitable bitumen volume in place was identified by integrating the geological factors that affect oilsand production,structure features,reservoir distribution and well pair deployment requirements,therefore,different levels of bitumen volume appraisal can be achieved,i.e.original bitumen volume in place,SAGD’able bitumen volume in place and exploitable bitumen volume in place.
