Drilling Equipment
Oilfield Equipment
This is a article that is going to cover oilfield equipment. The are many part to a drilling rig. I want to cover in this article is the top part of a drilling rig . There are far to many parts of a rig to cover, so I am just going to give a summary of the top of a drilling rig.drilling equipment I am going to explain a few article's covering the Rig from top to bottom. The top being the crown block to the bottom being the drill bit.
The crown block is a piece of equipment that is located a the top of the rig. This is were a the country's flag is placed. The crown block is a piece of equipment that uses pulley to to hold the weight of all the pipe that is going down the hole. A pulley system is used to divert the massive amount of mass that the crown block has to support. The traveling block or pulley systemwill be connected with a wire rope to a traveling block. This is all supported by a big metal mast. The mast is what looks like a antenna tower in the distance.
A traveling block has almost the same function a crown block. The purpose of the traveling block is to use pulleys to divert a huge amount of equipment mass that will be lowered down the dill hole. To give you an idea of the price of a crown block, they range from about $14,000 USD to all most $80,000 USD. The weight that a traveling block can hold will be from about 400,000 thousand pounds up to 900,000 pounds.This example should give and idea about the huge amount of equipment weight that is lowered down a drilling rigs hole. Of course this is for the land rigs.
The traveling block in then connected to a top dive. There are 2 different types a rigs a top drive and a rotary table/Kelly. The Top drive drilling rig is one that uses a power swivel or top drive in order to do the drilling. A rotary table or Kelly does the same thing but is located on the rigs main plat form. The Top drive will be used by the traveling block. The top drive land rig is more pricey but is considered to be a more efficient land rig , taking less people to use.
