摘　　要：本文提出了弹塑型水泥石改造的3种方法,通过室内实验优选出弹塑材料,并进行了配套的弹塑性评价。结果表明改造后的水泥石具有抗折强度高、脆度系数低、弹性模量低等优良力学性能。该成果在吉林油田龙深2平1井固井中得到成功应用,固井质量全井优质。In this paper,three methods for the reconstruction of elastic-plastic cement stone are put forward,the elastic-plastic materials are optimized by laboratory experiments,and relevant matching elastic-plastic evaluation is carried out as well.The results show that the cement stone after reconstruction has superior mechanical performance such as high breaking strength,low brittleness coefficient and low elasticity modulus.The research results are successfully applied in the well cementing of Longshen 2 Ping1 well in Jilin oilfield,and the quality of well cementing is superior in the whole wells.
