摘要:
本实用新型是一种油井机械防砂用柔性接头,它可最大地实现两被连接筛管间的弯曲,便于防砂筛管下入井斜较大的井内,它是由摆杆(1)、防转槽(2)、防转螺钉(3)、外套(4)、密封环(5)、防松螺钉(6)、接头(7)组成,此种接头结构简单,抗拉伸强度大,弯曲性能好,应用范围广,适用于各种筛管间的连接。
摘要(英):
The utility model relates to a flexible joint for the mechanical sand prevention of an oil well. The utility model can achieve the bending between two connected sieve tubes in furthest degree. The utility model is convenient for a sand preventing sieve tube to be arranged in a well with a larger well inclination. The utility model is composed of a swing rod (1), an anti-rotation slot (2), anti-rotation bolts (3), an outer sleeve (4), a sealing ring (5), loose-proof bolts (6) and a joint (7). The flexible joint for the mechanical sand prevention of an oil well has the advantages of simple structure, large tensile strength and good bending performance, and is suitable for connecting various sieve tubes.
