套管变形 meaning in English
casing deformation
Examples
- The reason analysis of mudstone creep on casing damage
泥岩蠕变导致套管变形损坏机理分析 - Casing damages are classified into deformation , breakage and sealing damages
摘要套管损坏主要分为套管变形、破损和密封性破坏3类。 - The actual applied results prove that this method is of validity and availability , it paves the way for further explaining casing deformation
实际应用结果验证了该方法的正确性和有效性，可为进一步解释套管变形奠定基础。 - Abstract : the stimulation treatment of & quot; loosening rock by the dilatancy of explosive waves & quot; is tested in the casing well 4242 for studying its result and its influence on casing . the result of the field test shows that this test is successful in technology , the oil production of the well is 4 times as much as that of it before the test ; the deformation of casing is local , and the result of the strength calculation shows that the deformation will not destroy casing
文摘:为了研究“压胀松动”增产技术的增产效果和对套管的影响,在延长石油管理局子长油矿对4242井进行了现场实验.该技术采用强动载波在地层深处叠加的方法,造成压胀条件,松动岩石,增大近井带渗透率,提高油井产量.施工后,该井产量增加为原来的4倍多.本次实验工艺上是成功的,首先是按设计要求引爆了炸药,其二是由于采取了保护措施,使套管变形局限在施工段处,不影响下泵,不影响油井生产;套管强度校核分析也证明了套管不会破坏.施工后地质效果明显 - The surface of natural fracture ( crack ) is parallel to the orientation of maximum principal stress . the principle orientation of anisotropic permeability reservoirs agrees with the orientation of the maximum principle stress . many engineering problems ( e . g . bore - hole stability , casing deformation failure during drilling , reasonable arrangement of wells , the optimum design of hydraulic fracture and so on ) are influenced by the in - situ stress orientation
天然裂缝面和裂隙面与最大主应力方向平行；在各向异性低渗透率油田中主渗透率方向与最大水平主应力方向趋向一致：在钻井过程中井壁稳定性，套管变形和损坏，油田开发井网合理布置、水力压裂优化设计等都与地应力方向有关。
