Axial compensator Model: Axial model mainly used to compensate non-metallic axial displacement compensator to be compensated lateral or axial displacement and horizontal displacement synthesis, with the ability to compensate for angular displacement, but generally do not use universal compensator to compensate for angular displacement. Tube frame design requirements: 1, the installation axial compensator tube sections, in blind-side, elbow, variable cross-section of the pipe, a shutoff valve or part of their collateral pipeline valve and into the mains inlet Department should set the main fixed tube rack. Main fixed tube rack to consider bellows hydrostatic thrust and deformation of the elastic force. Thrust is calculated as follows: Fp = 100 * P * A Fp- push axial pressure compensator (N), A- corresponds to the effective area of ??the bellows average diameter (cm2), P- this pipe conduit maximum pressure (MPa). Axial elastic force is calculated as follows: Fx = f * Kx * X FX- compensator axial elastic force (N), KX- compensator axial stiffness (N / mm); f- coefficient, when the "pre-distortion" (including pre-deformation △ X = 0) when, f = 1/2, otherwise f = 1. In addition to the pipeline area, you can set a fixed pipe rack in the middle. Intermediate fixed tube holder from time to consider the role of the pressure thrust. 2, between two fixed pipe rack pipe segment can only set an axial compensator. 3, the compensation should be near the end of the fixed tube rack, if it is too long, according to the first guide frame settings required to set the guide frame, the maximum distance the other guide frame press computing: LGmax- maximum guide spacing (m); E- Pipeline elastic modulus (N / cm2); i-tp pipeline moment of inertia (cm4); KX- compensator axial stiffness (N / mm), X0- rated displacement compensation amount (mm). When the compensator compressive deformation, the symbol "+", when the tensile deformation, in line with the "-." When the wall thickness of the pipe wall thickness according to the standard design, LGmax selected according to relevant standards. 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 Shengli Oilfield bellows compensator, and successfully applied in Jiangsu Oilfield station X17 wells, packer soft mudstone 1645-1696.6 m interval of the well water-swellable easy to shrink Trail Formation compensation, creating our own R & D expansion bellows application deepest records. 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, the underlying technology Research Institute of Petroleum Engineering Academy of Engineering and technical personnel in the field of research, the decisive use of heat pipe technology expansion bellows compensator, passed the expansion bellows packer well section, and the kickoff, steady 500 m ramp operations and twice from the drilling operations, the success of shale wells packer segment of the expansion of the Yi River. 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 to produce plastic deformation process, which enables organizations to undergo a plastic material scope of loading and unloading, found in the course of stress corrosion damage compensation issues 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 material.
