摘要： A pipe-handling system includes at least two pipe-handling units arranged in a vertically displaceable manner along respective guide tracks of, respectively, first and second portions of a tower. The pipe-handling unit is provided with lower and upper rotary units spaced apart vertically on a chassis. Each of the rotary units is provided with a rotatable tong and a hanging-off device. A method is for inserting and withdrawing a pipe string in/from a borehole by the use of the pipe-handling system.

摘要： There is described a device for vertical tool guiding for a drill floor (1), where there on the drill floor (1) is arranged at least one rig (2a, 2b, 2c), as the each rig (2a, 2b, 2c) is arranged on a rig foundation (21) supported on the drill floor (1) rotatably about a first, vertical axis (A) and arranged to be able to displace a tool (24a, 24b, 24c) in a horizontal working sector (S
a , S
b , S
c ) that in a vertical projection at least touches or cuts through the central axis (C) in a through drill floor opening (11), each rig (2a, 2b, 2c) being provided with a vertical guide track (22).

摘要： A circulation unit and an arrangement are arranged to continuously circulate drilling fluid during drilling. A housing is provided with a center bore arranged to accommodate a portion of a pipe. The center bore includes upper and lower sealing elements. The sealing elements are provided with center openings which, by the expansion of said sealing elements, are closable or fit tightly against the pipe by the abutment of an inner sealing surface against the pipe. Each of the sealing elements is connected in a fluid-tight manner to a packing pipe which is located in the housing and which is rotatable around the center axis of the center bore. The packing pipe is surrounded by a packing assembly fitting tightly between the periphery of the packing pipe and the housing.
