摘要
In view of the acoustic and resistivity logging data from Yingcheng Formation in Shiwu oilfield in Songliao Basin,the fractures are identified using methods of variable scale fractal, dual-laterlog and microspherically focused logging. There are three different shapes of fractures on the log curves, which reflect the properties of identified fractures. Also, the fractures development in five intervals of Yingcheng Formation in Shiwu oilfield is predicted and its relationship with single well productivity is discussed. The results show that near-horizontal fractures and low-angle fractures are the main factors to control single well productivity.
