Steel Tooth HDD Horizontal Directional Drilling Hole Opener Trenchless Reamer

Product Description:      

    Horizontal Hole openers, also known as HDD reamer, are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes.

The working principle of the horizontal hole openers produced and sold by our company Huichi petro:

    The trenchless oriented drilling pipe laying method is a construction technology that uses cliff soil drilling tools, pipeline detection and other technical means to lay, repair and replace underground pipelines without digging trenches on the surface. It uses a drilling rig placed on the surface, uses water jets or extrusion to form holes, and receives signals from the drill bit on the surface to control the drilling trajectory. The construction process is divided into three stages: drilling guide holes, reaming, and pipeline pulling back.

    The hole expansion is generally completed several times by connecting reamers of different diameters. Different types of reamers can be selected according to geological conditions.

    Our company Huichi petro produces and sells rock reamers suitable for various strata, soft rocks like limestone and sandstone, hard rocks like granite and basalt, etc. We can also help you choose the right cone palm to increase the drilling speed and service life. The size of the water jet hole can be designed according to the aperture of the reamer during construction.

The combined roller drill bits we sell have the following features:

    We can also customize 3-wheel, 4-wheel rock reamer, 5-wheel or more-wheel rock reamer according to the required back expansion force and drill pipe size of the customer. There are many choices of thread types, such as API, IF, FH, etc. However, for different rock types, rock reamer is such a product, and diamond drill bits are generally used. Generally, the most suitable reamer drill bit is selected according to the hardness of the rock. Seal type: rubber seal and metal seal roller palm are available.

According to the lithology of the drilled formation, the following principles should be followed when selecting the drill bit type:

  1. In the shallow well section, the rock is loosely cemented, and the drilling speed of the drill bit and the prevention of mud packing are mainly considered;

  2. In the deep well section, due to the long tripping stroke, the penetration of the drill bit is mainly considered;

  3. When the outer row of teeth of the drill bit out of the well is severely worn, it is advisable to use a drill bit with gauge teeth;

  4. In the well section prone to deflection, it is advisable to use a drill bit with small slippage and more and shorter teeth;

  5. When using a drill bit with inlaid teeth, it is advisable to use a drill bit with wedge teeth;

  6. When drilling diamond limestone, it is advisable to use a drill bit with double cone teeth or projectile teeth;

  7. When there are more shale in the formation or the density of the drilling fluid is high, it is advisable to use a drill bit with a larger slippage;

  8. When the formation is limestone or sandstone, it is advisable to use a drill bit with a smaller slippage;

  9. When drilling hard and highly abrasive formations, it is advisable to use a pure rolling ball tooth or double cone tooth drill bit;

  10. The extended nozzle and unequal diameter combination nozzle drill bits should be preferred for the optimal drill bit hydraulic parameters.

How to order:

    Sizes, cutters type, connections;Please specify special requirements.

Product Features:

  1. The product is used for the reaming of the oil, gas, petrochemical, sewage, power and fiber optic pipelines in the no-dig horizontal directional drilling;

  2. The types of back expanders include squeeze expansion type, flow channel type, cutting type, barrel type, rock roller type, etc.;

  3. The wear-resistant belt on the extruded transition section reduces the friction of back dragging, protects the barrel wall and prolongs the service life;

  4. The surface hardness and hard layer of the connection end are evenly distributed, which is durable, stable and reliable, and improves the service life of the drill pipe;

  5. The internal split water channel design prevents mud from entering the barrel chamber, reducing the weight of the back dragging of the hole;

  6. The cutting and expanding teeth are made of special high-alloy materials with good impact resistance and wear resistance;

  7. The spiral rotating spray design can replace water nozzles of different calibers according to different construction conditions.
