Based on post-refracturing production data and water cut,considering that only primary fracture exists,its efficiency is coupled by adjusting parame...

This paper also studies the principle respectively how glass fiber grid prevents and controls reflection crack,and introduces corresponsive construction crafts in detail.
Compared with the conventional presplitting methods, the shaped charge is obviously more effective in presplitting blasting and especially useful in controlling the presplitting slots.
In the normal nondistended state,this area coincides with the most caudad portion of the manometrically determined LES located within and caudad to the diaphragmatic hiatus.
In the treatment of these wells,micro-seismic and tilter meter were used to monitor the fracture spreading.After refracturing,the production histories of oil wells were matched with nume...
(4) The palaeotectonic movements resulted in the complicate stages of fractures, the relations between fractures were cutting, confinement, tacnode and so on, and formed 2 types 6 groups fractures.
