Description
技术领域
本实用新型涉及一种适用于油田采油管柱、地热热水井管柱、油气集输及化工产品管线输送等场所的耐磨防腐内衬隔热油管。
背景技术
目前在油田实际生产过程中普遍采用纯光管(未加任何隔热保温措施)采油管柱进行生产，这种采油方式存在原油自身温度大量损失的问题。在油管防腐处理上，通常采用在油管内表层涂上防腐涂料的解决措施，由于油管内的锈污不易清除干净且涂层较薄，因此存在防腐层易脱落、使用寿命短等问题。对解决抽油机井杆管偏磨，普遍采用玻璃内衬、防偏磨井口等技术，这些技术存在玻璃内衬易破碎、防偏磨井口操作使用工作量大，防偏磨效果较差等问题。
发明内容
本实用新型的目的是提供一种耐磨防腐内衬隔热油管，以解决降低原油从井底流到井口过程中原油自身的温度损失并改善原油在井筒中的流态的技术问题；还有效的解决油管柱杆管偏磨，油管内腐蚀、结垢、结蜡等技术问题。
本实用新型所采用的技术方案如下：
一种耐磨防腐内衬隔热油管，在油管(1)内固定嵌装一内管(2)，并在油管(1)和内管(2)之间固定嵌装一层隔热层构成隔热管(3)，内管(2)的长度大于油管，内管(2)的两端面突出包裹在油管(1)端面之外，隔热层固定在内管(2)和外管(1)之间。
在隔热层(3)和内管(2)之间安装一层薄钢管(4)，即隔热层(3)及薄钢管(4)固定在内管(2)和油管(1)之间。
所述的内管(2)为热塑性高密度聚乙烯复合材料或超高分子量聚乙烯复合材料，内管厚度为3.5mm。隔热层(3)为气凝胶纳米超级绝热毡隔热保温材料，隔热层厚度为3mm。薄钢管(4)的作用是防止内嵌内管时将隔热层损坏，其厚度为0.5mm。
本实用新型的优点是：可有效的减少井下原油及热水从井底流动到井口的原油自然热量损失，提高井口原油温度及热水井井口温度；可彻底解决油管的内腐蚀和柱杆管偏磨等技术问题，减少杆管损坏，减少井下作业工作量；能降低抽油机井杆管之间的摩擦阻力，降低抽油机载荷并达到较显著的节电效果；最终达到节能减排、减少减少杆管损坏，减少井下作业工作量，大大降低石油开采成本。
附图说明
图1是本实用新型的结构示意图。
图2是图1的沿A-A方向剖视图。
图3是图1的沿B-B方向剖视图。
具体实施方式
如图1、2、3所示，一种耐磨防腐内衬隔热油管，包括油管、油管内防腐耐磨层、油管内薄钢管、油管内隔热层组成的油管。在油管(1)内固定嵌装一内管(2)，并在油管(1)和内管(2)之间固定嵌装一层隔热层(3)，在隔热层(3)和内管(2)之间安装一层薄钢管(4)，内管(2)的长度大于油管，内管(2)的两端面突出包裹在油管(1)端面之外。此时耐磨防腐内衬隔热油管的两端面为内管端面，耐磨防腐内衬隔热油管的外表面为油管的外表面。
