摘要:
A flexible pipe body layer and method of producing a flexible pipe body layer are disclosed. The method includes coextruding an inner sub-layer and an outer sub-layer, wherein the inner sub-layer and outer sub-layer comprise a polymer, and wherein the inner sub-layer has a lower modulus of elasticity than the outer sub-layer.
摘要:
A method for completion of a lateral wellbore using a high pressure multibore junction assembly, which comprises a tubular main leg and a tubular lateral leg. The tubular main leg is secured within a main wellbore and the tubular lateral leg is positioned through a lateral wellbore. The tubular main leg and the tubular lateral leg may be stabilized relative to each other as the multibore junction assembly is lowered into the main wellbore.
摘要:
A riser and a method for reducing the risk of failure of a riser system comprising a riser (100) arranged between an installation and a subsea well the riser (100) having a bore (116) for conveying fluids therebetween, the method comprising the step of providing at least one vortex shedding member (111) in said bore (116) of said riser (100) and flowing the fluid between the subsea well and the installation.
摘要:
A pipe comprises a pipe wall formed of a composite material of a matrix and a plurality of reinforcing fibres embedded within the matrix, wherein the composite material in at least one region of the pipe wall is pre-stressed. The composite material in at least one region of the pipe wall comprises or defines at least one of a level of pre-tension and pre-compression.
摘要:
A pipe (70) having a pipe wall (72) comprises a composite material formed of at least a matrix (74) and a plurality of reinforcing fibres (76) embedded within a matrix (74). The matrix (74) defines a continuous structure and the fibres (76) are variably distributed within the continuous matrix structure (74). In one embodiment the fibres (76) are distributed radially throughout the continuous matrix (74) from zero at the region of the inner surface (78) of the pipe wall, and are increased in a direction towards the outer wall (80).
摘要:
A tool string disposed in at least one tubular having upper and lower threaded connections to connect to a drill string. The tool string includes a shock reduction tool, which includes an anchoring tail piece axially and rotationally fixed to the at least one tubular. A universal bore hole orientation (UBHO) muleshoe sub is disposed at an upper end of the shock reduction tool. A downhole electronics package coupled to the UBHO muleshoe sub.
