在对松辽盆地北部齐家一古龙地区泥岩裂缝油藏形成机理进行研究的基础上，应用多重分形理论计算了该区地反射层在不同区域内断裂体系的多重分形谱f（a）。通过对各区断裂体系多重分形谱特征的分析，发现多重分形谱f（a）和a高值区与泥岩裂缝油藏分布存在较好的对应关系。这不仅表明断层伴生裂缝是该区泥岩裂缝的主要成因类型，而且也表明断裂体系多重分形谱特征是定量描述泥岩裂缝油藏油气运移、聚集条件的一个重要参数。笔者根据这一规律，对该区泥岩裂缝油藏有利分布区进行了预测。
Based on the study of formation mechanism of mudstone fractured reservoirs in Qijia-Coulomb area in the north of Songliao Basin, the multifractal spectrum f (a) of fault system in different reflection zones in this area was calculated by using multifractal theory. Based on the analysis of the multifractal characteristics of the fault systems in each area, it is found that there exists a good correspondence between the f (a) and a high values of multifractal spectrum and the distribution of mudstone fractured reservoirs. This not only shows that the fault associated fracture is the main type of mudstone fractures in this area, but also shows that the fractal multifractal features of fracture system is an important parameter to quantitatively describe the hydrocarbon migration and accumulation conditions in mudstone fractured reservoirs. According to this law, the author predicted the favorable distribution area of mudstone fractured reservoirs in this area.
