    Abstract: B9~B8H are the corresponding well groups for injection and production in Bohai River facies A oilfield. There are poor reservoir bands about 100~300m away from the injection well B9, with poor connectivity between oil and water wells. The wellhead pressure of the injection well rises rapidly, resulting in long-term under injection. The water drive ... Show More

    Abstract: This study probes the brittle fracture mechanisms of an S32205 duplex stainless steel tee pipe (DN300×10 mm) subjected to mixed-mode I/III loading under internal pressures spanning 10 to 30 MPa, leveraging advanced finite element analysis to address reliability concerns in high-pressure oil and gas transport systems. Drawing on recent fracture mech... Show More

    Abstract: The loss and dilution of ore are two important indicators in the evaluation of goaf operation. In order to more timely and accurately reflect the loss and dilution rate after the end of each stope mining, this paper uses BLSS-HL three-dimensional laser scanning system to scan two goafs (724 # -2,714 #) in a deep mining area of a gold mine, and esta...
