摘要
针对目前井口原油频频被盗、采油井口丝堵封堵失效、丝堵拆卸困难、防盗措施差等问题,研制了一种FS型内装式井口防盗装置。本装置含一套内装式丝堵及专用拆装扳手。丝堵采用端部为内圆结构的设计,安装后,与节流器、卡箍头处是平齐的,使用一般工具根本无法拆卸,与之相配套的专用扳手采用横牙卡瓦的形式,在装卸丝堵的过程中,能够顺利咬住丝堵内壁,进行丝堵的拆卸与安装。该装置有效地解决了长期以来油田上所困扰的原油被盗问题,大大降低了生产成本及工人的劳动强度,减少了油井周围的环境污染。
For the problems of blank plug fixing in well head, such as crud oil stolen, failure aboutthe plug, difficulty in assembling and disassembling the plug, inefficient methods in anti-theft, a FSanti-theft units fixing inner hole in the well head was developed. It included a screw plug and a spe-cific wrench, and the plug was designed for perforated one end which was accordant with one endface of the choke or hub, and it had no way to disassemble the plug with assual tools at all. The re-lated wrench was designed for slips with lateral teeth. And it can seize the inner wall of the hole ofthe plug smoothly and assembled and disassembled the plug. It solved the problem of the oil stolenafter fixing the units, and lowered the production cost and workers＇ labor capacity, reduced the envi-ronmental contamination.
