下寺湾油田柳洛峪南沟区注采井网调整

Adjustment of Injection-Production Pattern in Liuluoyu Area of the Xiasiwan Oil Field

通过对下寺湾油田柳洛峪南沟区综合地质研究及在原有不规则的反七点法(230 m×240m)井网的基础上,2009年按矩形井网,排距为80-100 m,井距300 m,钻调整井21口,平均单井生产113 d,累计产油3522.33 t,平均单井年产油167.73 t。

Though the compositive geology research, based on the primary irregular inverted seven -spot well pattern（230 m ×240 m） ,following inverted nine -spot well pattern in 2009, adjust array pitch to 80 - 100 m, well spacing to 300 m, in 21 well drilling, single well producing 113 days in average, accumulated output is 2522. 33 , single well output is 167.73 t in an average.
