The roller cone bit should be performed as follows:1. The roller cone drill bit is activated near the well's bottom, and the pump's displacement is gradually increased to the required level.2....

Tricone drill bit is a widely used drilling bit. When the roller cone bit works, the cutting teeth contact the bottom of the hole alternately, and the rock breaking torque is small. The contact area b...

Ⅰ. The impact and crushing effect of roller cone bitDuring drilling, the bit and its cone rotate around the bit axis. The teeth of the cone rotate on their own axis due to rock resistance, and the te...

Ⅰ. The necessity of using rock reamer hole openerRock reamer hole opener must be used in rock formations. At present, rock reamer hole opener can be divided into hob type and tooth wheel type accordi...

Ⅰ. Manufacturing requirements for PDC core bitsWhen manufacturing, people often ignore an important problem, that is, many environmental conditions are complicated. Corrosion or other special conditi...

1. The larger the diameter of a reamer, the larger the errorAppropriately reduce the outer diameter of a reamer according to the specific situation, reduce the cutting speed, appropriately adjust the ...

The main parameters of the operation control of rock reamer are the push-pull force applied to the reamer by the drilling rig (pull force in the case of reverse reaming, and thrust force in the case o...

Ⅰ. Reaming constructionWhen laying small-diameter pipelines (communication, power, etc.) with horizontal directional drilling rigs, it is usually possible to drag the pipelines back while expanding t...

The reaming design includes reaming grading, the selection of reamer, assembly of reaming drill tool, assembly of clearing drill tool, drilling pressure, torque, rotate speed, and mud displacement, et...

The tricone drill bit is metal sealed rolling bearing, which can stably drill at medium and low drilling pressures with medium and high speeds. It is an ideal choice for the upper section of the well....

The tricone drill bit is a device specially used in petroleum drilling engineering. It can cut the underground rock through the cutting wheel and break it through the cone to achieve downward drilling...

The popular types of drill bits are Drag bits, Tricone bits, and PDC bits.1. Drag bitDrag bit price is cheaper than Tricone bits and PDC bits, in some shallow water well drilling with soft formation, ...

Polycrystalline Diamond Compact Bit is also named PDC bits, diamond bits. Base on the difference in raw materials, it has Matrix body bit and Steel body bit. You can contact with our sales representat...

1. The three cone bit adopts a floating bearing structure. The floating element is made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance. The ...

We all know that there are different stratums when using the three cone bit. Therefore, the manufacturing of the three cone bit requires much attention, otherwise, it will not be able to deal with var...
