高压注脂密封枪
本技术属于油田生产测井、环空测井
,具体涉及注脂密封枪。
技术介绍
目前在油田生产过程中测井射孔、井下事故处理等工作中会使用注脂泵和空压机,国外他们是以空压机作为动力,带动注脂泵工作,由注脂泵将密封脂通过管线送到控制头部位,密封脂在电缆与流管之间运行,阻止井内的油、汽、水向外溢流或喷发。而在国内,由于测井时间过长、空压机很难保证,注脂泵工作的气压,因此往往是工作一段时间就停下来,造成一些溢流或者喷发的现象。要想空压机有足够的气压,就要配备一个,专用发电机,来带动空压机,这样安装起来,或在现场施工,是件很麻烦的事,所以有些单位利用绞车上气源来带动注脂泵工作,在这种情况下,绞车不可能常时间高速运转,只能工作一段时间停一段时间,再发现溢流或喷发时再启动,这样在安全和环保方面都达不到要求,所以在我国范围内,目前很难实现无污染、无溢流、无喷发的情况下来完成整个测井任务。
