机械卡堵水工艺不断改进和完善,在卡封管柱优化和技术配套方面取得了较大的进步。应用封上采下机械卡堵水工艺管柱,在原有的Y221机械堵水工艺管柱基础之上,配套应用定位热洗装置,解决了管柱洗井问题,有效延长了管柱的有效期,同时改进可取式桥塞应用于封堵底水。
Mechanical card water plugging technology continues to improve and improve in the card sealing column optimization and technical support has made great progress. The utility model is characterized in that a mechanical stuck water blocking process pipe string is adopted on a sealing sheet, a locating hot washer device is applied on the basis of the original Y221 mechanical water blocking process string to solve the problem of the well string washing and effectively prolong the effective period of the pipe string, At the same time improve the desirability of plugging used in plugging bottom water.
