摘　　要：现有的开发实例中,注水生产的油田在井网部署的井距和井排距确定之后,会按照井网开发方案布井。在油藏条件分布不均的情况下,按照顺序或盲目地钻井很可能造成经济上的浪费。基于油藏属性及几何约束的局部自动布井生成算法,将井网部署之后的钻井先后顺序与几何约束条件相结合,并用油藏网格的属性进行约束,在无人干预的情况下自动部署井网,并可在结果上进行井点、井网线的适当修改,以提高油田的经济效益。In the existing development example, the oil field produced by the water injection will be arranged in accordance with the well development plan after the well spacing and well line spacing of the well pattern are established. In the case of heterogeneity of reservoir conditions, drilling in order or blindly costs a lot. Based on the local automatic routing well pattern algorithm on reservoir properties and geometric constraints, the drilling procedure after the well pattern deployment is constrained by the geomet- ric constraint conditions and the properties of reservoir grid properties in order to improve the economic benefits of oil fields. It can deploy the well pattern automatically in the absence of intervention and can modify the well and well line appropriately.
