针对准噶尔盆地东部火烧山油田储集层裂缝发育的特点 ,描述了实施脉冲干扰试井的压力曲线异常现象。客观评价了火烧山油田储集层部分裂缝发育具有规模较大 ,纵向上切深高 ,横向延伸长 ,裂缝宽度大等特征。对于干扰试井的压力曲线异常 ,分析认为是由于裂缝的特殊空间分布加之大注入量直接导致大裂缝的形成 ,使得裂缝类似与一个矩形管流动通道产生管流虹吸作用所至 ,并且基本上看不到时滞现象
Aiming at the characteristics of the fractures in the Huoshaoshan oilfield in the eastern part of the Junggar Basin, the pressure curve anomaly of the pulse well test is described. It is objectively evaluated that some fractures in the Huosuoshan oilfield have larger scale, vertical cut depth, lateral extension and larger crack width. For the abnormal pressure curve of the interference well test, it is considered that due to the special spatial distribution of fractures and the large injection amount, the formation of large fractures is directly caused, and the cracks are similar to the flow siphon effect of a rectangular tube flow channel, and basically No delay phenomenon
