摘要
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 。
Aimed at characteristics of formation fracture growth in Huoshaoshan oilfiled in Zhungeer basin, pressure abnormal cases from interfere testing are described. Main characteristics of the fracture growth are large scale, vertical deep incision, planar long extend, fat width and so forth. It is claimed that due to both special distribution and great injection rate big fractures are developed like as rectangle pipe flow siphon. It is clear that time lag phenomena may be not found in fracture development.
