Corner columns to produce legs on a oil drilling and use in a liftable team for cats.

摘要

The invention relates to a drilling rig PETROFIFERA DESIGNED FOR THE DEPTHS OF OCEANS OF LARGE AND CONSISTS OF AT LEAST ONE FOOT AND A PLATFORM HAVING A PUMPING SYSTEM. THE PIE DE LA TORRE CONSISTS OF A NUMBER OF PILLARS OF CORNER TOGETHER WITH BARS OF CROSS CONSOLIDATION AND EVERY PILAR CORNER comprises a outlet pipe (26) LARGELY BYPASS IN WHICH IS PLACED an inlet LARGE PART VOID. The annular space (27) between the inner outlet duct wall and the outer wall of the inlet pipe is filled with a curable material such as concrete, capable of transferring forces between the lines. The outer diameter of the outlet pipe (26) is approximately constant over the entire length of the column (24), AND THE CARTER OIL IS DEFINED that the outer diameter of the inlet duct (28) is approximately constant WHILE THE THICK IT INCREASES YOUR WALL from the top section (I) COLUMN corner to the lower section (VI) CORNER COLUMN. ACCORDING TO a preferred construction thickness TI WALL inlet duct (28) step increase from about 30MM. In the top section FOOT 150MM CARTER TO SOME. ON FOOT lower section. BUILDING CORNER COLUMN MAKES THE PRODUCE derricks PETROLIFERAS drillable who can work DEPTHS OF OCEANS wholly below 200 meters.
