摘要
综合利用岩心、薄片及成像测井资料,对库车坳陷克深2气田的单井裂缝发育特征进行分析,采用构造应力场数值模拟法对井间裂缝发育特征进行定量预测,并讨论裂缝发育主控因素及裂缝与产能的关系。结果表明:克深2气田主要发育NNW—NW走向的直立和高角度剪切构造裂缝,岩心裂缝开度主要分布在0~0.2 mm,微观裂缝开度一般为0.01~0.06 mm;裂缝充填物多为方解石,平均充填系数约为0.63。断层带裂缝性漏失量高,裂缝线密度和裂缝孔隙度均为高值,是裂缝的最有利发育区;背斜高点的裂缝线密度低,但裂缝开度、裂缝孔隙度和单井产能均为高值,裂缝整体发育程度较高;岩石中钙质组分的增加或泥质组分的减少有利于裂缝的发育;水下分流河道及河口坝微相裂缝发育程度较高,水下分流河道间微相裂缝发育程度相对较低。在裂缝性储层开发过程中,要注意对储层采取保护措施,避免产能下降过快。
        Fracture characteristics of individual wells of Keshen-2 gas field were analyzed using data of cores,thin sections and imaging logging,and interwell fractures were predicted quantitatively by stress field numerical simulation. The primary controlling factors of fracture development and the relationship between fracture and gas production were also discussed.The results demonstrate that upright and high angle shearing structural fractures with NNW-NW strike mainly develop in Keshen-2 gas field. Fracture aperture from core data are mainly between 0 and 0.2 mm,while that of microcosmic fractures are generally between 0.01 and 0.06 mm. Fractures are mainly filled by calcite,and the filling coefficient is approximately0.63. Drilling fluid loss in the fractured zone is large,and the fracture linear density and fracture porosity are both high in fault belts which are the most favorable areas for fracture development. Fractures at the top of anticlines have low density but high aperture and porosity,and wells in these areas have high gas production,thus fractures develop well at the top of anticline in general. The increase of calcium content and the decrease of clay content are beneficial to the development of fractures. Fractures in underwater distributary channel or estuary dam develop better than those among interdistributary channels. Within the development process of fractured reservoir,reservoir protective procedures should be taken to avoid the rapid drop of production capacity.
