摘要：

To study the shale gas optimal exploitation method in Dongying subsidence area, this paper extracted 13 groups of shale cores with different buried depths (3315.85-3485.07 m) from the upper Es4 to lower Es3 at Dongying subsidence area in Shengli oilfield. Authors measured and analyzed five physical mechanical fracability related parameters, the results of five parameters show that the shale in Dongying subsidence area has a good exploration prospect. According to the longitudinal comparative analysis on different depth shale, four parameters fracability related were determined. A fuzzy comprehensive decision method was used to obtain the quantified fracability evaluation results, which provide an optimal reference for shale gas development. The results show that the shale fracability in investigation area decreases with the increase of burried depth, the shale from depth 3315.85-3366.35 m should be choose over other depth. ©, 2015, China Coal Society.
