一种水平井热采套管头
摘要：
本实用新型涉及一种水平井热采套管头，主要包括悬挂器(1)、压盖(2)、本体(3)，并且悬挂器(1)下端与内层套管(5)相连接；其特征在于：本体(3)分别与压盖(2)及表层套管(6)相连接，压盖(2)套装在悬挂器(1)上，且压在悬挂器(1)外台阶处；悬挂器(1)由本体(3)内腔中部的台阶定位，悬挂器(1)的外侧凸起部分装有密封圈(4)；在本体(3)的中部还设计有旁侧孔。本实用新型有效解决了稠油水平井钻井固井过程中的有控固井和采油作业的安全生产问题，实现了热采水平井有控固井及套管的可靠悬挂和准确定位，确保了钻井固井施工的安全性及井口的可靠性。
摘要（英）：

The utility model relates to a horizontal well thermal collecting bushing head which mainly consists of a hanger (1), a gland bush (2) and a body (3). The lower end of the hanger (1) is connected with a lining bushing (5). The utility model is characterized in that the body (3) is respectively connected with the gland bush (2) and a surface casing (6). The gland bush (2) is arranged on the hanger (1) and presses on the position of the outer steps. The hanger (1) is located by the steps arranged in the middle part of the cavity of the body (3). An obturating ring (4) is arranged on the convex part at the outside of the hanger (1). A side hole is arranged in the middle part of the body (3). The utility model effectively solves the safe production problem of the controlled cementing of well and the oil extraction operations in the drilling and cementing processes of thick oil horizontal well, realizes the reliable suspension and the accurate locating of the controlled cementing and bushing of the thermal collecting horizontal well.
