Abstract


The technology of the the research abroad 1960s dual gradient drilling (DGD), in theory, can solve the technical problems encountered in traditional offshore drilling technology in deep water. But in many dual-gradient method and system, only the Norwegian AGR's no the riser mud recovery (RMR) system has been a wide range of industrial applications, significant economic and environmental benefits. This paper combination of national science and technology major projects - large oil and gas fields and coal bed methane development sub-project the seabed mud lift drilling technology research (2008ZX05026-001-12), to carry out the the seabed mud lift drilling technology and undersea mud suction module prototype research and development, etc. research. The main contents are as follows: an undersea mud to inhaled module prototype structure design combined with the environmental characteristics of China's deepwater drilling operations, according to the technical characteristics of the seabed mud lift drilling, to develop the seabed mud inhaled module design parameters and technical requirements, determine applicable to our deepwater drilling the seabed mud inhaled module design, design prototype structure, draw the 500m and 1500m water depth of inhalation module principle prototype technical drawings. 2 seabed mud inhalation the module prototypes key technology of deepwater drilling environment and seabed mud lift drilling technology requirements, solve the seabed mud inhaled module key technical problems, including inhalation module the sealant core design, rotary dynamic sealing its cooling system design, automatically rotate the a sealed rotary shaft coupling surface treatment process, inhalation of module drilling fluid pressure and liquid level control system, discharge device and the internal rotating assembly locking structure design, the design and application of seabed mud suction localization module provide technical support. 3 undersea mud suction module digital prototyping and simulation research using Advanced 3D CAD / CAM engineering software - Pro / E, developers mud suction module digital prototyping, prototype virtual assembly, guarantee mud suction module prototype assembly. Seabed mud suction module design results using ABAQUS finite element software to carry inhaled module prototype simulation study, including the use of non-linear finite element method to verify the the sealant core mud recovery drilling riserless feasibility analysis of the design parameters of the rubber core sealing performance and service life of the rubber core to provide the technical support for the rubber core optimization design and life extension; finite element analysis conducted the seabed mud inhaled module main parts, and optimize the prototype design. Design and Application of localization submarine mud lift drilling technology and its key equipment and provide technical support. 4 undersea mud inhaled module prototype machining and test research under the seabed mud suction module design results plotted inhalation the module prototypes processing technical drawings, processing inhaled module principle prototype. According to the submarine mud lift drilling technical characteristics, the development of undersea mud inhaled module indoor test program, test the submarine mud inhaled module prototype performance to optimize prototype design, according to test results, to improve the design parameters, inhalation module the industrial prototype design and manufacturing to provide a basis for seabed mud.
