Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 Shown is a specific embodiment of the deep water jet downpipe drilling experimental device of the present invention. In this embodiment, the device mainly includes a soil box 22, a string system, a hoisting system, a water supply and drainage system, a loading system and a measuring system.
[0038] Combine below figure 1 The specific structure of the deep water jet downpipe drilling experimental device of the present invention will be described. Among them, the hoisting system is mainly composed of a hoisting crane 1, a suspension cable and a dynamometer 2, which are responsible for hoisting the column system. The string system includes a conduit 9 , a drill pipe 10 , a centralizer 11 and a drill bit 12 . Wherein, the drill pipe 10 , the centralizer 11 and the drill bit 12 are respectively threaded and assembled tog...

The invention discloses an experiment device and a method for deep-water jetting, guiding pipe releasing and well drilling. The device comprises a soil box, a pipe column system, a hoisting system, a water supplying and discharging system, a loading system and a measuring system, wherein rock and soil which are used for forming a deep-water jetting seabed environment are arranged in the soil box; the pipe column system is arranged in the soil box; the hoisting system is used for hoisting the pipe column system; the water supplying and discharging system is connected with the soil box and is used for discharging sewage and feeding clear water into the soil box; the loading system is used for applying transverse and vertical load to the pipe column system; the measuring system is connected with the pipe column system and is used for measuring and recording displacement, deformation and stress of the pipe column system during a deep-water jetting process. According to the device disclosed by the invention, a platform is further provided for researching parameters of deep-water jetting and guiding pipe releasing through simulating a deep-water jetting, guiding pipe releasing and well drilling environment and a deep-water jetting, guiding pipe releasing and well drilling operating process.
Description
technical field [0001] The invention belongs to the technical field of marine engineering and oil drilling, and relates to an indoor simulation and operation parameter testing experiment platform and method for catheter drilling under deep water jetting, in particular to an indoor simulation of jet drilling in a catheter well section capable of simulating deep water drilling Experimental device and experimental method. Background technique [0002] Deepwater drilling is risky and expensive. At present, the basic technological process of the jet-down pipe drilling adopted in the deep-water drilling pipe section is as follows: the jet drilling tool assembly (composed of a drill bit and a motor, etc.) is placed inside the pipe, and connected with the pipe-feeding tool. Extend the catheter shoe a certain length. When the conduit reaches the mudline, it will drill into the formation by its own weight, and the pump will drive the motor to rotate the drill bit, and the circulatin...
