26、清防蜡技术，主要有机械清蜡技术、热力清防蜡技术、表面能技术、化学药剂清防蜡技术、磁防蜡技术和微生物清防蜡等。3.1机械清蜡技术机械清蜡机械处理法的原理是采用清管器。刮蜡刀或刮蜡钩将管壁上沉积的石蜡刮掉，这种方法已应用了几十年，在有些油田中的使用效果相当不错，但在一些油田中使用时也暴露出其清蜡量不够的缺点。除了上面列出的清蜡方法外，还有一些其它清蜡方法如化学放热法、电加热法及新近发展起来的超声波清蜡法和生物清蜡法等。自喷井清蜡技术包括机械刮蜡设备和机械清蜡设备。主要设备包括绞车、钢丝、扒杆、滑轮、防喷盒、防喷管、钢丝封井器、刮蜡片和铅锤。刮蜡片依靠铅锤的重力作用向下运动刮蜡。上提时靠绞车运动拉动

27、钢丝经过滑轮拉刮片上行，如此反复定期刮蜡，并靠液流将刮下的蜡带到地面，达到清蜡的目的。铅锤的质量矿场常用下列经验公式计算6： W=(68)Pt （3-1）式中W铅锤质量，kg，Pt油管压力，Mpa。当油井结蜡相当严重时，下刮蜡片已经有困难，则改用钻头清蜡的办法清除油井积蜡，使油管内通径。达到刮蜡片能顺利地起下时则可改回刮蜡片清蜡。钻头清蜡的设备与刮蜡片清蜡设备类似，其不同点是将绞车换成通井机，钢丝换为钢丝绳，扒杆换成清蜡井架，防喷管改为10m以上的防喷管，钢丝封井器换为清蜡闸门，铅锤换为直径3244cm的加重钻杆，下接清蜡钻头。通常油井尚未堵死时用麻花钻头，它既能刮蜡又能将部分蜡带出地面。但是

28、结蜡非常严重时麻花钻头下不去，这时就要使用毛刺钻头，将蜡打碎，然后用刮蜡钻头将蜡带出地面。自喷井机械清蜡方法是最早使用的一种清蜡方法。它是以机械刮削方式清除油管内的沉积的蜡，合理的清蜡制度必须根据每口油井的具体情况来制定。首先要掌握清蜡周期。使油井结蜡能及时清除，保证压力，产量不受影响。清蜡深度一般要超过最深点或析蜡点以下50m。有杆泵抽油井机械清蜡，它是利用安装在抽油杆上的活动刮蜡器清除油管上的蜡目前用的是尼龙刮蜡器。尼龙刮蜡器表面亲水不易结蜡，摩擦系数小，强度高，耐冲击，耐磨，耐腐蚀，一般都是铸成型，不须机械加工，制造方便，其高度为65m。值得注意的是，螺旋要有一定的夹角以保证油流冲击螺旋

29、面时可以产生足够的旋转力，使尼龙刮蜡器在上下运动时同时产生旋转运动，尼龙刮蜡器成圆柱体状，外围有若干螺旋斜槽，斜槽的上下端必须重叠，以保证管内30度都能刮上蜡，斜槽作为油流通道，其流通面积应大于12.17cm2。为稠油泵游动阀座孔面积的3.2倍以上。尼龙刮蜡器内径大于抽油杆1mm，外径比油管内径小4mm，在抽油的过程中，作往复运动的抽油杆带动刮蜡器作上下移动和转动，从而起到刮蜡的作用。3.2热力清防蜡技术热力清防蜡技术是利用热能提高抽油杆、油管和油流的温度，当温度超过析蜡温度时，则起到防止结蜡的作用，当温度超过蜡的熔点时，则起到清蜡的作用，一般常用的方法是热油处理法、热水清蜡法、油井直接电加热清理法。（1）热油处理法热油处理法的原理是用热洗车装载油罐底部的原油，将原油加热到110摄氏度以上注入油井的油套环形空间或集油管线中，热油直接与
