Introduction to Reamer

1. Types of reamer

There are many types of reamer, mainly including expansion and contraction wellbore reamer, sliding keyway reamer and fixed rib reamer with carbide. These tools are different from spiral stabilizers. Their upper and lower inclined shoulders are welded into a cone with carbide welding rods, which have the performance of cutting, reaming and breaking keyways. Another common reamer is similar to a general stabilizer, but shorter than a general stabilizer, and its working surface is about 20cm. This reamer has a slope to help the drill bit break free from the keyway. Wellbore expanders vary in shape and size. Their main function is to expand the reduced wellbore diameter so that drilling tools such as drill bits and stabilizers can pass smoothly.

2. The role of reamer

The reamer plays a very important role in the oil drilling process. During the drilling process, the wellbore diameter will gradually decrease. If the wellbore is not expanded in time, the drill tool will get stuck or unable to pass, thus affecting the drilling progress. The reamer can effectively expand the wellbore and ensure the smooth progress of the drilling process. In addition, the reamer can also destroy the keyway, allowing the drill to pass through the wellbore more smoothly.

 

3. The importance of the reamer

The reamer is one of the indispensable tools in the oil drilling process. During the drilling process, the change of the wellbore diameter is inevitable. If the wellbore is not expanded in time, the drill will get stuck or unable to pass, thus affecting the drilling progress. The reamer can effectively expand the wellbore and ensure the smooth progress of the drilling process. Therefore, the quality and performance of the reamer are crucial to the smooth progress of drilling.

 

In short, the reamer is an important tool in the oil drilling process, which can effectively expand the wellbore and ensure the smooth progress of the drilling process. When choosing a reamer, it is necessary to select the appropriate type and specification according to the actual situation to ensure the smooth progress of drilling.
