Abstract

本实用新型涉及一种油田修井工具,即安装在油管上的油管旋塞阀。在钻井过程中,发现井口内喷或内涌时用扳手操作能迅速安全关闭,起到安全钻井作用。油管旋塞阀包括管状阀体,管状阀体内有上、下阀座,在上、下阀座之间有球封,球封过液孔等于或大于62mm。在井上正常修井过程中即能起到防喷作用也能通过它对油内刮腊、刮盐等作业。通过结构改进,提高了产品的适应性。

Description

油管旋塞阀
技术领域 
本实用新型涉及一种油田修井工具,即安装在油管上的油管旋塞阀。在钻井过程中,发现井口内喷或内涌时用扳手操作能迅速安全关闭,起到安全钻井作用。
背景技术
在现有技术中,旋塞阀主要是安装在方钻杆下部,由阀体,球封,上、下阀座,密封件,弹簧及操作杆等零件组成,每一个旋塞阀并配有手柄。其缺点是当油田在射孔作业施工中,由于新射开的油层地层压力高,装上旋塞后中途完井生产,在生产过程中发现油管堵塞,需要对井内的油管进行清腊施工。由于普通旋塞内径小(40mm),清腊设备(外径58mm)根本通不过去。最后只有进行压井上作业施工,严重影响了原油生产。
实用新型内容
本实用新型的目的是针对上述不足而提供一种结构改进,适应性强的油管旋塞阀。
本实用新型的技术解决方案是:油管旋塞阀包括管状阀体,管状阀体内有上、下阀座,在上、下阀座之间有球封,球封过液孔等于或大于62mm。 
本实用新型的优点是:在井上正常修井过程中即能起到防喷作用也能通过它对油内刮腊、刮盐等作业。通过结构改进,提高了产品的适应性。
下面将结合附图对本实用新型的实施方式作进一步详细描述。 
附图说明
图1是本实用新型结构简图。 
具体实施方式
参见图1,油管旋塞阀包括管状阀体1,管状阀体1内有上、下阀座2、3,在上、下阀座2、3之间有球封4,球封4过液孔等于或大于62mm。62mm内径主要是为了通过外为58mm的刮腊工具。在施工中如发现井喷现可以立即关闭旋塞阀门。油管旋塞阀安装在油管上,一旦在钻井过程中井口发生内喷时,可用手柄,放入操作杆,顺时针方向转球封90度,扳到指示位置“关”即能控制井喷,排除井喷继续开钻时,用扳手扳到“开”位置即可,使用方便、安全。
凡是中途完井生产的安装油管旋塞阀,以便于进行测试、清腊、清盐等施工。
