摘　　要：哈萨克斯坦North Buzachi油田(简称NB油田)为注水开发的边底水稠油油藏,在大力加强油藏地质精细研究基础上,积极推广应用水平井开发油藏新技术,在油田主体部位采用直井和水平井组合式开采,挖潜注采井井间剩余油,而在油藏边部油水过渡区则以提高难采储量动用为主。生产过程中,在油田主体部位的水平井表现出含水上升快、产量递减迅速等特征,未取得预期效果。研究结合油藏地质特征,剖析水平井开发油藏的生产特征,以油藏数值模拟为手段,优化部署新区水平井,探究水平井开发该类油藏的适应性。North Buzachi（ NB） oilfield in Kazakhstan is an ordinary edge and bottom water heavy oil reservoir under waterflooding development. In this oilfield,based on vigorously strengthening fine research on reservoir geology,we actively promoted the use of new technology of horizontal wells reservoir development. For main parts of this oilfield,combination production of vertical wells and horizontal wells was used to develop the remaining oil between injection and production wells. However＇ for oil- water transition area at the reservoir edge,improvement to recoverable reserves utilization was our main target. During production process,horizontal wells in oilfield main parts have features that water- cut will increase quickly while production declines rapidly,so the reservoir failed to achieve the desired results. In this research,we combined with the geological characteristics of this reservoir,analyzed the production characteristics of horizontal well development reservoir and through numerical reservoir simulation,optimized the deployment of horizontal wells in new areas and explored the adaptability of horizontal well development in this type of reservoir.
