摘要(Abstract)：

针对大庆外围低渗透油田储层特点 ,以油藏工程分析和数值模拟为手段 ,对水平井进行了优化设计。系统研究了水平井与常规井网互相协调的注采方式 ,论证了采取早期注水对保持水平井区地层压力和提高水平井稳定产量的重要性。大庆低渗透油田水平井开采实践表明 ,水平井的生产能力是同类地区压裂直井的 3～ 6倍 ,水平井技术在低渗透油田具有一定的应用前景
According to the reservoir characteristic of the low permeable oil fields in the peripheral part of Daqing, this paper performs an optimized design of horizontal well using reservoir engineering analysis and numerical simulation. It studies the injection production method with which horizontal well and normal pattern coordinate each other and proves the significance of early water injection for keeping reservoir pressure in the horizontal well area and improving the stable production of horizontal well. the practical production of horizontal well in the low permeable oil fields in Daqing shows that the productivity of horizontal well is 3 6 times of the fracturing straight well in the same type area, and the horizontal technique is prospective in low permeable oil fields.
