受油藏特征影响,不同油藏类型井网调整的原则、模式不同,效果评价指标也各有侧重。相对于其它类型油藏,断块油藏具有构造复杂的特征,井网调整效果受构造影响因素较大影响,因此在断块油藏井网调整效果评判中应考虑构造这一因素。本文提供的断块油藏井网调整后开发效果评价方法是在确定评价的目标和范围的基础上,根据每一个评价指标对评价对象或评价内容的相对重要性确定出每一个评价指标的权重系数,结合具体某断块油藏的实际静态数据或动态数据确定每一个评价指标的数值,采用模糊综合评判方法先对每一个评价指标进行单因素评价,然后对所有指标的进行多因素综合评价。
Affected by the characteristics of the reservoir, the principle and mode of well pattern adjustment for different types of reservoirs also have different emphasis on the evaluation indexes. Compared with other types of reservoirs, the fault block reservoirs have the characteristics of complex structures and the effect of well pattern adjustment is greatly influenced by the structural influence factors. Therefore, structural factors should be considered in the evaluation of well pattern adjustment effect of fault block reservoirs. This paper provides a method for evaluating the development effect of the fractured block well pattern based on the determination of the objective and scope of each evaluation index and the weight of each evaluation index according to the relative importance of each evaluation index to the evaluation object or evaluation content Coefficient, combined with the actual static data or dynamic data of a certain fault block reservoir to determine the value of each evaluation index, using fuzzy comprehensive evaluation method for each evaluation index first single factor evaluation, and then for all indicators of multi-factor comprehensive evaluation .
