Abstract Deep and ultra-deep carbonate reservoirs are the focus of exploration and development in future.However, the problems of high caruso rhodiola pressures in the treatment process, a limited effective etching distance of acid, great acid leak-off, and poor adaptability of the acid system are encountered in this type of oil and gas reservoir.T
Laser transmission welding can be effectively used in fabrication of laminated parts.In the present work an attempt was made to fabricate a polymeric laminate structure made of polymathic methacrylate (PMMA) and aluminum 6061-T6 by laser transmission welding process.A series of laser welding experiment has been carried out to analyze effect of lase
To solve the problem of insufficient melt pool width feature extraction accuracy caused by splash, arc light, and other interferences in the metal deposition process, a melt pool width extraction method based on the variable step size erosion model is proposed according to the characteristics of the spatial distribution of the melt pool size featur
