A brief introduction about the developing background,progress,and specifications of hydrohammer and pneumatic downhole hammer made in China and abroad is given in this paper.

潜孔锤的研制与发展刘广志(地矿部高咨中心·北京)中国研究潜孔锤及其钻探工艺始于1958年底,至今已有35年的历史,先后开发了两大类潜孔锤。即:液动潜孔锤(Hydro-hammer)(前称冲击回转钻探);风动潜孔锤(PneumaticDownTheHo...

Through comparison of DTH hydro-hammer with hydraulic rock drill,two ideas are presented:(1)Thedevelopmetn of DTH hydro-hammers can be refered to the features of high hydraulic dressure,lowflow rate and high avilability engergy coefficiency of hydraulic rock drills;(2)The liquid spring property of drilling fluid playsan important role in improving the improving the operating performance of hydro-hammers.

通过时液动冲击器与液压凿岩机的比较,提出了两点看法:(1)液压凿岩机的大液压小流量及高的能量利用系数,对液动冲击器的研制有借鉴作用;(2)水的液体弹簧性质对提高液动冲击器的工作性能具有重要作用。

The mechanism of vaporization, cavitation and water-hammer of drill fluid occurring on the suction stroke of drill pump is investigated. The devices for determining the characteristic curve of drill fluid vaporization are introduced. Characteristic curves were worked out on site. Comparison between these curves and the characteristic curve of running water vaporization show that drill fluid is much more susceptible to vaporization than running water , and the higher the temperature, the greater the differential...

The mechanism of vaporization, cavitation and water-hammer of drill fluid occurring on the suction stroke of drill pump is investigated. The devices for determining the characteristic curve of drill fluid vaporization are introduced. Characteristic curves were worked out on site. Comparison between these curves and the characteristic curve of running water vaporization show that drill fluid is much more susceptible to vaporization than running water , and the higher the temperature, the greater the differential of vaporization pressure of the two. A mathematic model for vaporization characteristic curve fitting is given by means of least square method for the convenience of quantitative analysis.

对钻井泵吸入过程中钻井液产生汽化、汽蚀与水击现象的机理进行了探讨。介绍了用直接观察法和噪声测试法测取钻井液汽化特性曲线(汽化压力与温度的关系曲线)的装置,并用直接观察法装置测取了长庆油田钻井液的汽化特性曲线。将该曲线与自来水汽化特性曲线相比较表明,钻井液比自来水更容易汽化,且温度越高,二者汽化压力差值越大。当泵缸内钻井液局部温度达80~90℃时,钻井液的汽化压力比自来水高20~30kPa。这个差值足以对合理使用钻井泵构成严重危害,把按自来水计算的无汽蚀工作条件用于钻井液,必然导致钻井液的严重汽蚀。最后,为便于进行各种定量分析,给出了用最小二乘法对汽化特性曲线进行拟合的数学模型。
