可换套筒稳定器是石油、***及地质勘探钻井工程中，防止井斜变化的重要工具，在配备较大刚性的钻铤和施加较大钻压的使用情况下，合理使用稳定器，使井斜变化率和方位变化率较小，能避免产生“***”，并提高井深质量和钻井速度，降低钻井成本。通过更换扶正套，以适应不同井径，提高使用寿命。可换套筒稳定器由主体、稳定套、护套组成。稳定器工作表面的耐磨材料有四种：①表面镶嵌硬质合金柱；②表面镶嵌金刚石复合体；③表面低温钎焊硬质合金块；④表面堆焊耐磨焊条。Replaceable Sleeve Stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process. In order to ***oid the
"hotdog" and h***e the rate of change and location of the well deviation reduce during drilling, we should utilize the tool with reasonable way under the
case equipped with strong drill collar and inflicted more bigger pressure which Improving the quality of the well and the speed of drilling, reducing the
cost of drilling well. Through changing sleeve to suit for different borehole diameters to lengthen operating life.
The advantage is that the sleeve can be changed quickly and easily after sleeve hardfacing is wornout. This kind of stabilizer is especially suitable
for working in directional well .There are four kinds of abrasive resistant materials on the working surface of stabilizer: insert tungsten carbide butt***,
insert diamond compound body,low temperature welding tungsten carbide pieces,hardfacing electrode on the surface and so on.
