摘要
西峰油田白马中区微裂缝发育,自投入开发以来,裂缝见水现象非常严重,识别裂缝带是该裂缝性储层的重要问题。但该油田有关裂缝的资料种类以及数量是非常有限的,只有常规测井资料,而利用常规测井方法来识别天然裂缝的难点在于裂缝本身的复杂性及每种测井测量值受多种因素的影响,因此采用分形几何中的变尺度分形(R/S)方法对常规测井曲线进行处理,来识别裂缝的发育情况,有利于该区的高效开发。
Micro-fracture is developed in the middle part of Baima on Xifeng Oilfield. Since this zone has been in exploitation, it is very serious that water breakthrough because of the fracture and it is very important to identify fracture with the fractured reservoirs. But the type and quantity of materials about fracture in this area are limited except the conventional logging data. However, the fracture itself is complex and every logging measurement is influenced by many factors are the difficulties to indentify natural fracture using the conventional logging methods. Therefore the identification of fracture using the variable scale fractal （R/S） technique to deal with conventional well logs is advantageous to the efficient exploitation of this area.
