摘　　要：为了解决多套井组划分和调剖井组初选的问题,根据油水井的平面井点坐标,以所选调剖水井与其他水井之间的最小直线距离划分调剖井组,定义了井数因子、井距因子和夹角因子三个参数,根据三者乘积定义了调剖井组的均匀度,形成了调剖井组初选的定量评价方法。研究认为:调剖井组均匀度取值为0~1,此值越大,油井相对于中心调剖水井的分布越均匀,更能保证调剖后各油井受效均匀;均匀度值为1的调剖井组将作为后续进一步筛选的候选井组。该方法能快速识别和划分多套调剖井组,评价调剖井组油井的分布均匀程度,为后续进一步筛选调剖井组提供资料基础。In order to solve the division of multiple well groups and initial selection of profile control well groups,the profile control well groups are divided based on the plane well point coordinates of oil and water wells and the minimum linear distance between the selected profile control well and other wells.Three parameters,namely well number factor,well spacing factor,and angle factor are defined,and the uniformity of profile control well groups is defined based on the product of the three,forming a quantitative evaluation method for the initial selection.The results indicate when the uniformity value is 0~1,the larger this value,the more uniform the distribution of the oil well relative to the central profile control well,which makes sure that each oil well receives even effect after profile control.The well group with a uniformity value of 1 will be used as a candidate one for further screening.This method can quickly identify and divide multiple profile control well groups,evaluate the distribution uniformity,and provide a data basis for further screening.
