摘要
坑道采油技术是稠油开发的一项新技术,主要利用蒸汽辅助重力泄油(SAGD)的原理,通过油砂层下面的巷道系统向油砂层中钻水平井进行热力采油,对开采特浅层、超稠油油藏和进一步提高稠油采收率(可达50%以上)有较好的应用前景。简要介绍了坑道采油技术在国外稠油油田的应用情况,并重点介绍了加拿大阿尔伯达油砂技术研究局利用竖井和坑道进行的UTF采油工艺以及水平井蒸汽辅助重力泄油开采技术,并介绍了与常规稠油开采方法不同的坑道内钻井施工,为国内开发稠油油藏提供了技术借鉴。
The Underground Test Facility （UTF）, a new technique for producing heavy oil reservoirs, used the theory of SAGD. It used the tunnel under the sandstone to drill horizontal wells in the sandstone to recovery oil thermally. It has very good application prospects for the shallow and heavy oil reservoirs and improving the oil recovery which could be up to more than 50%. The paper describes the application of UTF in overseas oilfields with emphasizing on the UTF application by Alberta Oil Sands Technology Research Authority （AOSTRA） and the SAGD technique. This paper introduces the tunnel drilling which is different with the traditional heavy oil reservoir and provides the technique guidelines for the development of heavy oil reservoirs.
