稳定器 Dongyuan

1,整体螺旋稳定器按安放位置分为钻柱型和井底型。其工作表面的耐磨材料（即扶正面）有常用表面镶嵌硬质合金柱、有
表面镶嵌金钢石复合体、有堆焊耐磨焊条、还有低温钎焊硬质合金条等多种形式。该产品由于螺旋带上的硬化处理，具
有硬度高、韧性好、耐磨性强、使用寿命长等特点。

based on the installation place, the stabilizer can be divided into the drilling string type and the near bit type. the
working hardfacing surface (also called wall contact ) materials available separately are (1) carbide insert,(2) inserted
diamond compound, (3) low temperature
brazing tungsten carbide slug, (4) surface
bead welding abrasive welding rod, etc.
built with inserted round carbide in spiral
ribs，the product is characterized by high
hardness, good toughness and powerful wear
resistance, as well as long service life.

2,滚轮稳定器用于钻井作业中的各种铰孔工作，尤其在钻研磨性地层时能起稳定和扩眼的双重作用。该工具
配有三种结构的滚轮，分别用于软地层、中硬地层和硬地层的铰孔工作。另外，当滚轮磨损减小后更换新
的滚轮即可延长稳定器的使用寿命。

the rotary reamer is designed for various reams in drilling operation. especially it can perform the double
functions of centralization and ream when drilling in very abrasive formations. in addition, it can extend
the service life by replacing with the new ones when the rollers are worn and become smaller.

3,可换套稳定器由一个本体和一个扶正体连接组成，它不但具有整体螺旋稳定器的功能，并且可以通过更换不同的扶正
套，以适应不同的井径，也可更换相同的扶正套来延长稳定器的使用寿命。尤其适用于打定向井。

integral mandrel sleeve stabilizer is made of a
body and a replaceable sleeve. changeable sleeve
stabilizer has the functions of integral spiral blade
stabilizer. it can be suitable for different well
diameters by changing different bearing sleeves,
and also extends the service life by replacing the
same kind of bearing sleeve.
