大庆油田属非均质、多油层的陆相砂岩油藏，进入开发中后期时，为保证连续高产、稳定，必须依靠技术进步开发以前不能够采出的薄油层。薄油层的一个显著特点就是层间封隔段短，如果射孔作业造成水泥环破裂，会严重地影响固井质量，地下各层之间窜通，直接影响出油的质量和数量，甚至使新打的油井报废。在井下数百米深处进行的射孔作业，对水泥环的损伤是一个极其复杂的问题。从力学角度分析，射孔弹的聚能射流以超高速撞击由套管、水泥环、地层组成的复合体时，应力将以波的形式在介质里传播。为了探讨射孔时水泥环的损伤机理，系统地进行水泥环抗窜的综合试验研究，设计了模拟固井射孔的综合试验装置和多功能材料动态性能测试装置，对原浆水泥石和几种改性水泥石的动态力学性能进行了实验研究和模拟固井射孔试验，给出了具有较好抗冲击性能的水泥石的动态力学性能指标和部分改性水泥石的力学性能。
Daqing Oilfield is an inhomogeneous, multi-reservoir continental sandstone reservoir. In the middle and late stages of development, in order to ensure continuous high output and stability, it is necessary to rely on technological progress to develop thin oil reservoirs that could not be produced before. A notable feature of thin reservoirs is that the interval between layers is short. If the cement ring breaks due to perforation, it will seriously affect the cementing quality. The stratification between underground layers will directly affect the quality and quantity of oil produced, Newly hit oil wells scrapped. The perforation work carried out several hundred meters underground is an extremely complicated issue for the damage of the cement ring. From the mechanics point of view, when the charged jet of a projectile collides with a composite composed of a casing, a cement ring and a formation at a very high speed, stress will propagate in the medium in the form of waves. In order to study the damage mechanism of cement ring during perforation, a comprehensive experimental study on cement ring anti-channeling was systematically carried out. A comprehensive experimental device for simulating cementing perforation and a dynamic performance testing device for multifunctional material were designed. The dynamic mechanical properties of modified cement stone were studied experimentally and simulated by cementing perforation test. The dynamic mechanical properties of cement stone with better impact resistance and the mechanical properties of partially modified cement stone were given.
