The filtrational resistance beteen wells was big,and actuating pressure ascended,then absorbing thickness declined,the other is perforated interval is long,the contrast of adjustment oil reservoir is great,interlayer interference is great.
分析主要原因,一是注采井距偏大,井间渗流阻力大,启动压力升高,使吸水厚度下降;二是注水井射孔井段长,调整井油层条件差且层间差异大,层间干扰大,严重影响了二次加密调整效果。
