地质统计方法对井网适应性评价

WELL PATTERN COMPATIBILITY APPRAISAL BY APPLYING GEOLOGY STATISTICAL METHOD

通过引入钻井数学模型,对某油田的井网密度、砂体面积、砂体储量、砂体数量进行了地质统计。分别得到了单油砂体条件下,井网控制概率与井网密度关系,井网密度与水驱控制概率关系。运用加权处理,分别得到了油藏井网密度与井网控制程度关系,油藏井网密度与水驱控制程度关系。并应用上述模型对油田的井网适应性进行了实例分析。

In this article,the geological statistics have been performed in terms of well patten density,the sand body quantity of some oil field through introducing well drilling mathematical models.Relationships between well pattern density and well pattern control probability,well pattern density and water drive control probability have been reached under the single reservoir sand condition..Using weighting processing,the oil deposit well pattern density and the well pattern control degree relations separately;the oil deposit well pattern density and the water drive control degree relations are obtained.And through the application of the above model,the example analysis are carried out on the oil field well pattern compatibility.
