摘要
常规马笼头虽然在技术上已经比较成熟,但是由于设计上采用了小额定值的拉力棒结构,大大限制了处于遇卡临界状态下测井绞车电缆施加给测井仪器的张力。结合国内外同类产品特点和国内现有材料,研制出了国产可释放马笼头。文章介绍了该马笼头的组成、功能、性能参数和工作原理,并对研究的关键技术进行了阐述。通过各种基础性的试验,证明了其可靠性和稳定性。
The using of the conventional cable head bridle is very mature now,but some disadvantages can't be overcome because of the structures of the tension bar with smaller rating in it,which restricts the tension to logging instruments greatly by the cable in the winch when the instruments are in the critical conditions of sticking.The Releasable Wireline Cable Head was designed by combining the similar products' characteristics and existing materials.This paper introduces the constitutes,functions,parameters,working principle and critical techniques of the prototype.Many basic tests demonstrated the reliability and stability.The author points out that the Releasable Wireline Cable Head will be used more widely in the future.
