摘要
现文在Ｓｋｅｅｍ理论基础上，对随钻震击器在震击作业期间产生的震击力、冲量和卡点位移进行了详细的计算，为震击作业期间根据实际情况调节震击器的过拉力提供依据。文内还详细地分析了多种因素的影响关系，为钻柱设计时确定震击器的安放位置提供素材。
Abstract The paper has developed and consummated the theory of Skeem.Impact force、impulse and displacement of stuck point generated by jar during jarring operation have been calculated in detail.It offers to regulate the overpull of jar during jarring operation according to the case of the field.The interaction of some factors have been analyzed in detail,It guide to decide the displacement of jar in the drillstring during the design.
