摘要
针对目前分层注水工艺中所使用2个或2个以上封隔器的相互作用,使得管柱的变形量计算趋于复杂的问题。以水力压缩式封隔器分层注水工艺管柱为例,较详细的分析了管柱受力坐封前、坐封后和注水3个过程中的受力状态和变形情况,并对注水时层间压差引起的受力差异给出了重点分析,推导出了管柱在不同过程中的受力及变形计算公式。为层流注水工艺解决层间矛盾,调整油层平面上注水分布的均匀性提供了理论依据。
At present, due to two or more packer being usually used in separate zone water injection technique, as a result, calculation of string deformation becomes complicated. Hydraulic compression packer separate zone water injection technique string is taken as an example, loads and deformations of pipe string during three phases are studied in detail, including anchoring, setting, and water injection. In addition, the instance of pipe string stress is suited, as a result of interlamination pressure difference in water injection, equations derived to calculate stress and deformation during respective phases. The work provides theory for interlamination infusion techniques solving contradiction and adjusting the homogenization of water distribution on reservoir plane.
