Ⅰ. Manufacturing process of PDC cutterThe manufacturing process of PDC cutter mainly includes two stages:1. Manufacture of PDC cutter: The PDC cutter is sintered at high temperature (1000～2000℃) and hig...

Ⅰ. Selection of PDC cutter material1. Reasonable selection of PDC granularityThe choice of PDC grain size is related to the processing conditions of the tool. For example, when designing a tool for f...

1. Development of PDC cutterAs a superhard tool material, diamond has been used in machining for hundreds of years. In the process of tool development, from the end of the 19th century to the middle o...

PDC Core bits play an important role in geological exploration and are commonly used in the drilling construction industry.Ⅰ. Introduction of PDC Core bitThere is no significant difference between PD...

1. What is the purpose of a reamer?A reamer is a rotary tool with one or more teeth that is used to remove small layers of metal from a hole's machined surface. The hole is reamed to a specific si...

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....
