摘　　要：吐哈盆地温米油田在注水开发过程中,油藏的油水运动制约着油田的开发效果。为了准确掌握油藏的油水运动规律,有效地控制地下油水运动,解决油田开发中由于平面及剖面开采的不均衡性所带来的各种矛盾,文章从油井的生产特征分析入手,应用数理统计、油藏工程、数值模拟等方法,研究油藏水线推进速度,油水分布特征及含水变化特点,提出控制地下油水运动的措施意见,提高油田的开发水平。研究认为,合理的注采井网是搞好开发的先决条件,井距越小,水线推进速度越快,反之,井距增大,水线推进速度减小;连通率越高,连通方向越多,水驱波及体积越大,开发效果越好。通过实施,取得了良好的效果。In the waterflooding development of Wenmi oilfield, voir restricts the development effectiveness of the oil field. In water in hydrocarbon reservoir kinds of contradictory which is the movement of oil and water in hydrocarbon reserorder to control the movement regulation of oil and accurately and control the fluid medium movement effectively and also resolve all brought by the disequilibrium in the flat and profile production, this article begins with the analysis of production character of oil well, also uses the methodologies such as mathematical, petroleum reservoir, numerical analogue etc. to study the advancing velocity of reservoir waterline, the characteristics of oil and water distribution and water - cut variation, proposes the measures controlling underground oil and water movement so as to improve production level of oil field. The reasonable flood pattern is a precondition for a good devel- opment. The smaller well spacing kept, the faster waterline advanced. On the contrary, the longer well spacing kept, the slower waterline advanced; the better connection rate is, more orientation they connected; the more swept volume of water drive, the better develooment effectiveness. After implementation, good effectiveness is taken.
