摘要
Abstract
The extended drill pipe that is widely used for drilling of ultra-deep and ultra-long horizontal well most likely develops the deformation defect,during the heat treatment process and therefore can hardly meet the stringent cri-teria for the straightness for well drilling operation.Accordingly based on the bending morphology,a systematic research is conducted on the heat treatmentcaused deformation of the said drill pipe body,involving analyzing the formation charac-teristics of different types of deformation,and as a result six key incentive factors are summarized,i.e.,quenchingheating scheme,in-furnace fuel gas erosion,walking beam assembly accuracy,furnace chamber heating type,working state of tube discharging and transferring,and quenching rotary roller matching and press roller pressure parameters.Addressing the said influencing factors,corresponding control and optimization measures are formulated,and then subjected to pro-cess validity verification.The above mentioned research achievement can provide technical reference for suppression of heat treatment-caused deformation and straightness accuracy control of the extended drill pipe body.关键词
