【摘要】 稠油热采井因油井出砂导致非均匀载荷作用在套管上,严重削弱了套管的抗外挤能力,套管损坏日益加剧,制约了油井的正常生产。天津钢管公司针对上述问题,在不改变现有采油工艺条件下,开发出了非API标准规格为覬193.7mm×1617.9014mm,热采井用高抗挤毁套管TP120TH,成功地解决了这一困扰热采井开采中的重要技术难题。更多还原

【Abstract】 The collapse-resistance casing is seriously weakened by uneven load resulted from shakeout of steaming injection well. The increasing damage of the casing has influenced the oil well working. According to the above problems, non-API ? 193.7 mm×1617.9014 mm is developed by TPCO under the condition of existing technique. Using high collapse-resistance casing TP120TH has successfully resolved the key technical problems in exploitation of steaming injection well.更多还原
