摘　　要：中国油砂矿储量位居世界前列，如何经济有效地开发和完善配套的技术是面临的难题。对比分析了目前主要的油砂开采方式、特点，重点研究了油砂蒸汽辅助重力泄油技术的开采工艺、原理和布井方式。该技术通过在加拿大Christina Lake油田的成功应用，证明是一种有效的深部埋藏油砂油的开采技术。分析了中国油砂矿的分布范围和储层物性，针对埋深和油质特点，提出了合理的开采建议。油砂蒸汽辅助重力泄油开采技术的研究与成功应用，将促进中国油砂矿资源的开发利用。The reserves of the oil sand in China is ranked the tops of the world but how to effectively and economi- cally extract it and perfect the matching techniques are the facing issures met today. The main mining methods and characteristics of oil sand at present are compared and analyzed, the mining technologies, principles and patterns of well spacing of steam-assisted gravity drainage （SAGD） of the oil sand are focused. Through the successful appli- cation in Canadian Christina Lake Oilfield, the technique is proven to be an effective way to produce the oil sand in the deep part. The distribution of the oil sand and reservoir characteristics in China are analyzed. In light of the buried depth and the characteristics of the oil quality, the reasonable production recommendations are presented. Researches and successful application of the oil-sand SAGD techniques stated above will promote the development and uhility of oil sand resources in China.
