Two kind of separated perforating and pulse fracturing composite charges are studied.论述了低渗油气层的地质特征;研究了两种分离式射孔脉冲压裂复合弹.Macroscopic deviations from isotropy occur due to bedding, schistosity and also sometimes fracturing.与各...
Macroscopic deviations from isotropy occur due to bedding, schistosity and also sometimes fracturing.与各向同性相差很大的情况往往产生于层理, 片理,某些时候则由于断裂所造成.Therefore, CNOOC's proposed drilling fracturing with reasonable sanding recov...
