[Abstract]:As the core equipment of the underwater oil production tree system, the oil pipe hanger is the key equipment of the underwater oil production tree system. It is related to the success or failure of the deepwater oil development. In this paper, according to the requirements of the offshore oil development, the design and research of the oil pipe hanger are carried out, the key technical obstacles are breakthroughs and the localization of the underwater oil recovery tree system is realized. According to the API phase On the basis of comparing the characteristics of foreign products, a set of overall research scheme is put forward, and the installation process is elaborated in detail. The main structure of the hanger, the locking structure, the seal structure and the distribution of the electrohydraulic channel are detailed. The checking of the main structure and the force analysis of the locking ring are completed, and the suspension of the oil pipe is suspended. The concept design of the hanger tool is carried out. The three-dimensional model of the oil pipe hanger and its lower instrument is set up by SOLIDWORKS. The selection of the core components is completed. The strength analysis is carried out by using the finite element software ABAQUS to carry out the strength analysis of the main structure seat, the locking structure, the lock spring and the lower tool lock ring. In this paper, the sealing technology and sealing performance of the oil pipe hanger are studied in this paper. The sealing technology of foreign oil equipment company is analyzed. The technical characteristics of the foreign products are summarized and the performance indexes are compared. Through the analysis of the key seal technology, the high temperature and high temperature are pointed out. Under pressure and strong corrosion environment, the development direction of the seal of oil pipe hanger is new material and new seal structure. The mechanical analysis model and material model of the sealing structure of the tubing hanger are established. The sealing properties of the circular arc contact surface (seal I) and the inclined contact surface (seal II) of two different contact surfaces are established. The finite element model established in the ABAQUS software is analyzed. The maximum Mises stress, the maximum contact pressure and the contact pressure on the contact surface are analyzed by changing the interference amount of the seal, the pressure load, the temperature load and the modulus of elasticity, and the performance of the seal under the different working conditions is analyzed. The finite element simulation of the Mises stress and contact pressure of the elastomer under different compression rates is carried out. The performance analysis of the sealing structure is completed. Finally, the full text is summarized and the research work on the next step of the vertical tubing hanger is prospected.
