热敏式封隔器在红003现场应用二零一一年二月十一日目录一、前言二、封隔器座封和解封三、生产中出现问题四、分析问题的原因五、解决方法六、结论及建议一、前言在红003稠油井区，新试验共使用了4种热敏封隔器，由于第一次大批量使用热敏封隔器，很多经验不足，导致在使用中存在不能座封的现象，而且在生产中存在碰不上泵和杆不下的问题，经过我们现场分析原因加实践证明，弄清楚和封隔器配套的伸缩管在热采井内对防冲距的影响，因此减少修井次数和因修井耽误的产量，恢复油井的正常生产。二、封隔器座封和解封红003井区现在使用的4种封隔器，分别为瓦房店的SYZB331-152、辽河采研院的k361-150、胜利采研院的K331-150和双利公司的K341-152，共计124口井使用热敏式封隔器，占今年投产井数的53.9%。为了试验封隔器的座封效果，我们对在红003使用的4种厂家的封隔器选了9口井和没安装封隔器2口井在注汽的时候采用油管和套管安装压力表测试数据。下封隔器井油套压和温度值3-2/hD911493-2/hD911503-3/hD91154日期油压套压温度日期油压套压温度日期油压套压温度11.078.15.530011.078.05.729011.139.464.029011.088.66.530011.088.06.529511.1410.07.430011.098.66.730011.098.07.029511.1510.07.430011.108.76.830011.108.07.029511.168.26.428011.118.36.529511.117.46.529011.177.15.527011.129.37.030011.128.17.129511.187.15.527011.139.37.030011.138.17.129511.197.15.527011.149.37.030011.148.17.130011.209.06.829011.159.37.030011.158.27.230011.219.17.029511.169.07.030011.168729511.229.17.029511.17焖井11.17焖井11.239.17.028011.24焖井下封隔器井油套压和温度值4-6/hD912494-6/hD912853-3/hD91128日期油压套压温度日期油压套压温度日期油压套压温度10.267.75.028010.267.64.528011.137.86.528010.278.57.030010.278.56.328011.148.47.529010.288.36.729010.288.46.831011.158.57.429010.298.26.829010.298.47.031011.167.16.429010.307.56.528010.307.56.530011.176.15.028010.317.56.528010.317.56.530011.186.15.028011.017.97.028011.018.07.030011.196.15.028011.02停炉11.02停炉11.207.06.528011.038.37.328511.038.47.431011.217.67.129011.0487.329011.048.37.431011.227.67.129011.058.47.529011.058.37.531011.237.67.629011.068.47.529011.068.47.431011.247.87.330011.078.47.529011.078.47.431011.258.07.330011.08焖井11.08焖井下封隔器井油套压和温度值3-4/hD911713-4/hD911894-4/h91332日期油压套压温度日期油压套压温度日期油压套压温度11.266.04.627011.266.14.628011.038.27.225011.278.06.428011.278.26.829011.048.67.629011.288.26.728011.288.27.029011.0598.130011.298.26.729011.298.57.629011.068.78.030011.308.26.729011.308.57.629011.079.18.130012.017.65.828012.017.86.227011.089.58.330012.0287.129012.028.27.028011.098.98.030012.0387.229012.038.27.328011.108.78.030012.0487.228012.048.27.029011.118.78.030012.0587.228012.058.27.029011.129.38.530012.0687.228012.068.27.029011.139.38.530012.07焖井12.07焖井11.149.38.5300未下封隔器油套压温度值4-6/h912644-6/hD91265日期油压套压温度日期油压套压温度10.225.43.926010.267.34.623010.237.27.429010.278.56.528010.247.27.930010.289.36.628010.257.38.030010.299.36.828510.268.08.330010.308.96.528010.277.57.828010.318.96.528010.287.57.829511.018.97.028010.298.17.830011.02停炉10.307.57.229011.039.37.228010.317.57.229511.049.27.328011.017.57.229511.059.37.329011.02停炉11.69.37.329011.038.07.930011.79.37.329011.0487.930011.8焖井11.058.18.030011.6焖井二、封隔器座封和解封通过上面表格分析可以得出，在注汽的过程中，下封隔器井内的套管压力随着油管压力的上升而上升，降低而降低，而不是稳压在一个固定的数值，再和没下封隔器的井油套压做对比，不能证明封隔器完全座封。热敏式封隔器座封检验标准在正常注汽后三天后，...
