荆丘地区防止膏盐层挤毁套管的钻井完井工艺

COMPLETION TECHNOLOGY IN GYPSOLITH AND SALT FORMATION TO PREVENT COLLAPSING CASING IN JINGQIU OILFIELD

    摘要
  • 摘要: 膏盐地层塑性蠕动产生的非均匀载荷使套管挤毁或变形。解决的办法包括抑制或减轻非均匀载荷的产生和提高套管强度。本文介绍荆丘地区钻井完井过程中抑制非均匀载荷和提高套管强度的技术措施,特别是双层组合套管的设计和固井施工工艺。

     

    Abstract: The nonhomogeneity stress caused by plastical creeping of gypsolith and salt formation will casing collapse and deformate.The measures to prevent casing from collapsing and deformation include controlling and decreasing the effects of nonhomogeneity stress and improving casing strength.This paper introduce the measures of controlling nonhomogeneity stress and improving casing strength during completion and especially the design of double casing and cementing operation in Jingqiu oilfield.
