摘　　要：随着钻井技术的发展，水平井在超稠油油藏开发中的应用逐渐增加，地质设计及注采参数是决定其开发效果的主要因素。利用数值模拟技术，优化了具底水的厚层超稠油油藏水平井的垂向位置、井距、水平段长度；结合矿场生产动态、井筒热损失计算，优选了水平井的注汽速度、初期注汽量、注汽递增幅度、放喷排液量等注采参数。在辽河油田曙一区杜84块的现场应用表明，水平井方案设计合理，开发效果显著。With the development of drilling technology, the application of horizontal well in supper heavy oil reser- voir increases gradually. Geological design and injection-production parameters are the essential factors that influ- ence the development effect of horizontal well. Vertical position, well spacing and horizontal well length in supper heavy oil and thick reservoir with bottom water have been optimized through numerical simulation. Based on the a- nalysis of field production performance and the calculation of heat loss＇ in well bore, this paper provides the opti- mized injection-production parameters, including steam injection rate, initial steam injection volume, steam injec- tion increment and boosting fluid delivery, etc. Field practice in Du 84 block of Liaohe Oilfield shows that the de- sign program of horizontal well is reasonable designed, which has acquired obvious development effect.
