Mechanical Analysis Of Steam Injection String In Horizontal Well

With the rapid development of the petroleum exploitation industry,we have improved the technology of oil reservoir exploitation in order to pursue a higher production.The stress state of the horizontal well tubular column under different working conditions has been paid more attention by scholars.Considering the thermal recovery horizontal well gas injection pipe string in straight hole into the conditions and gas injection conditions force characteristics,analyzed by finite element numerical simulation method,calculated the gas injection string by force and deformation law at the position of wellhead and bottom separating device.Using finite element analysis software to study the transient analysis of the injection process of gas injection pipe string in a horizontal well.The theory and method of redevelopment of ANSYS by using Basic Visual language are described.Independent research and development of "mechanical analysis" software and introduce and apply this software.The research of thermal recovery horizontal well steam injection string mechanics and can accurately get steam injection of the stress law of string in into the conditions and steam injection conditions.Mechanical analysis software can calculate work and provide users with convenience.
