摘　　要：克拉玛依油田3种类型砾岩油藏具有各自不同的地质特征,结合油田典型层块的实际生产状况,分析了3种不同类型油藏油水运动规律与井网密度的关系,认为 、 类在构造高部位宜采用相对较大的井网密度,而 类油藏宜均匀布井;油田的井网部署要综合考虑沉积相和渗透率方向性等因素的影响,其井网形式不但要考虑强化注采系统的需要,而且要考虑井网形式的灵活性,为后期加密调整留有余地。The three types of conglomerate reservoirs in Kelamayi oilfield have different geologic characteristic.Combing with the actual producing performance of the typical intervals, this paper analyzes the oil and water movement rules of those three types of reservoirs and their relation to well density. It proposes that a relatively large density can be used for the high structure position of type ⅠandⅡ, while uniform wells can be arranged for type Ⅲ. For the relation between oil production and well density, large well space can be used in the earlier stage of type Ⅰ,and then local infilling is used according to the remaining oil distribution in the middle and high water cut stage. Large well density should be arranged in the earlier stage of type Ⅱ and Ⅲ, and the arrangement should be considered combining with the effect of sedimentary facies and permeability direction. Their pattern arrangement must aim at not only the demand for strengthen the injection-production system, but also the flexibility of the well pattern, so as to preserve a space for latter infilled adjustment. This paper introduces a determination method for partial reasonable well density, and suggests to use economic optimum well density as the evidence to determine the reasonable well space under the current market econormy condition.
