Hinge bellows has a universal ring in the circumferential direction have two pairs of orthogonal hinge structure. Developed by the Technical Research Institute of Petroleum Engineering, expansion bellows technology, following the high-temperature compensation after the Shengli Oilfield, Jiangsu Oilfield successfully applied in Taiwan X17 wells, packer water swelling of the soft shale wells 1645-1696.6 m interval easy necking formation, expansion bellows create applications developed our own deepest recorded. Taiwan X17 well is one exploration well, the design depth of 3019.29 meters, construction by Jiangsu Oilfield 40651JS team. The well was drilled at three open when Yancheng group reddish brown shale formation, the drilling process is easy water swelling necking, resulting in hanging card, sticking and other complex situations. For technical problems, Petroleum Engineering Technology Research Institute Academy of Engineering and technical personnel in the field of research, technology and decisive use of expansion bellows, expansion bellows passed well packer segment, and the kickoff, steady ramp operations 500 m and twice from the drilling operations compensation price, the successful containment of the Yi River shale well sections of expansion. The application of this technology expansion bellows, expansion bellows for further broaden the scope of application block complex formation and implementation of a single well packer longer segment complex formation has accumulated valuable experience in the construction site. Most bellows are made of stainless steel sheet produced by the disdain, the thickness of the pipe bellows generally 0.4-3mm. Its base molding process is the process of plastic deformation of non-metallic flexible compensation, which enables organizations experienced plastic material scope loading and unloading, stress corrosion found in the course of the destruction of the compensator abound, in order to overcome these two types of corrosion, commonly used method is molded corrugated compensator solid melting process to select the new high nickel bellows materials. Tetrafluoroethane compensation Features (1) the compensation of thermal expansion (2) non-metallic expansion joints can be multi-dimensional direction to provide greater compensation in less size range, the compensation due to piping installation error, the system error is inevitable, nonmetallic compensator can better eliminate installation errors. (3) no reverse thrust due to the main material for the fabric compensator, unable to pass, with non-metallic compensation simplifies design. (4) high-temperature corrosion-resistant fluorine plastics used silicone material with good heat and corrosion-resistant properties. Fortunately, the sealing performance under a variety of media effect, has a good seal.
