Drilling an Oil Well through Cementing Equipments

Drilling is a cutting process which is used to drill or make a hole in solid materials. The drilling bit is a rotational cutting tool which is usually a multipoint.

Drilling is the most common machine process and it has been estimated that about 75% of metal-cutting material is removed from all kinds of drilling operations.  In drilling process a circular hole is created which is accomplished with twist drill. An oil well drilling is also carried out through the similar process which is carried out with the help of cementing equipments to hold the well.

Importance of Float Shoe in the Drilling Process

The drilling of an oil well cannot be complete with the help of a float shoe is used in the drilling of oil and gas wells. It is a single cylindrical piece that functions as both a guide shoe and a float collar. The main purpose is to guide the drilling equipment during the entire process without hitching juts like guide shoe. It also has check valve to allow the passage of fluids in one direction only.

The oil drilling process is initiated by setting up the rig. First, from the starter hole the team drills a surface hole right into the pre-set hole. This is the place where the oil trap is located. There are five basic steps to drill the surface hole which is done by placing the drill bit, drill pipe and collar into the hole. Then attach the kelly and turntable to begin the drilling process.

Drilling an oil well is a massive project which is carried out with the help of workers and specialists. The geologists are hired to analyze the features of an area and to check whether there is oil or not. Then they will examine the type of surface which can be rocky, terrain and the type of soil. This also includes different types of field which are magnetic as well as gravitational field of the Earth.

The drilling holes are characterized by their sharp edge on the entranceway and burrs are present on the exit side. Inside the hole there are spiral feed marks. The drilling will be affected by the mechanical properties of the work piece due to presence of residual stress around the hole opening. There is a very thin layer of disturbed and high stressed material on the newly drilled surface.

Thread Lock Compounds

One of the important components which are used to hold the cementing products are the thread lock compounds. It is single component adhesive which is applied on threads of the fasteners like screws and bolts. This prevents leakage, corrosion and loosening. The thread –locking fluid might be applied before or after assembling the cementing equipments depending upon their make.

Cementing is a process that protects and seals an oil well. It is also used to seal a lost circulation zone where there is absence and flow within the well. It is basically used to plug an already existing well.

SledgeHammer Asia is known for its quality cementing equipments which is used for the drilling of an oil well. They help in smooth operation of the process.
