摘要：针对UnderRiver油田目前存在的水平段蒸汽干度损失大、含水率上升快和蒸汽吞吐采油量低等间题，在分析油藏储层物性和实际生产数据的基础上，综合油截数值模拟分析和财务净现值评价方法得到了4种不同注汽方式下的水平段最优长度值。研究表明：采用不同的注汽方式，其最优水平段长度不同，采用均匀注汽方式具有最好的采油效果，趾端注汽方式的采油效果最差；根据现场数据和生产经验提出蒸汽损失率概念，回归了
稠油油藏水平井水平段长度优化计算方程，该方程具有较高的精度和广泛的适用性。关键词：UnderRiver；稠油油藏；蒸汽吞吐；水平井；长度优化

Abstract: Aimed at the current problems of serious steam dryness-fraction loss, fast water cut and low oil produc-tion of the steam huff and puff in Under River Oilfield, based on the analyses of the reservoir physical properties and actual production data, the optimal length of the horizontal section under four kinds of the injection modes were obtained with the help of the comprehensive analysis of the reservoir numerical simulation and financial net present value evaluating method. The researches show that for different steam injecting patterns, the optimized horizontal section lengths are also different, the oil produced effects are the best for the uniform injection mode, while for the mode of the toe end injection, the achievements are-the worst; According to the field data and production experi-ences, the concept of the steam loss rate is proposed and the length optimization calculating equations for the hori-zontal sections in the heavy oil reservoir are regressed, and furthermore the equations have pretty higher precision and broader applicability.
Key words: Under River; heavy oil reservoir; steam huff and puff; horizontal well; length optimization
