In a drilling rig , the drill line is a multi-thread, twisted wire rope that is threaded or reeved through in typically 6 to 12 parts between the traveling block and crown block to facilitate the lowering and lifting of the drill string into and out of the wellbore. To make a connection is to add another segment of drill pipe onto the top the drill string. A segment is added by pulling the kelly above the rotary table, stopping the mud pump, hanging off the drill string in the rotary table, unscrewing the kelly from the drill pipe below, swinging the kelly over to permit connecting it to the top of the new segment which had been placed in the mousehole , and then screwing this assembly into the top of the existing drill string. Mud circulation is resumed, and the drill string is lowered into the hole until the bit takes weight at the bottom of the hole. Drilling then resumes.

The drilling line is reeved over a set of crow block and down to another set of sheaves known as travelling block. The hook connected to travelling block is used to suspend the drilling load. The drilling line is reeved around the blocks several times in order to meet required load. Static Derrick Load. Static derrick load equates to summation of fast line tension, dead line tension and hook load.

Wu, Z.. On most onshore rigs, weight on bit WOB is usually obtained from the deadline hook load measured by deadline the sensor installed on the deadline of the block-and-tackle system. To obtain a more accurate WOB, a measurement tool, called torque and tension sub TTS , has been developed to measure the load below the quill of a top-drive system. Theoretically, the load from the TTS, called the TTS hook load, is more accurate than the deadline hookload because the TTS measurement is not affected by the friction between the drilling lines and sheaves and the top drive rails. The downhole weight on bit DWOB is a key parameter in optimizing rate of penetration ROP and drilling optimization because accurate DWOB plays a very important role in improving the overall performance of a bit run. The objective of the work presented herein is to acquire rig parameters such as sheave efficiency, static weight of travelling block and friction between top drive and the rail by using theoretical analysis and regression analysis of acual drilling data.

This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below.

A traveling block is the freely moving section of a block and tackle that contains a set of pulleys or sheaves through which the drill line wire rope is threaded or reeved and is opposite and under the crown block the stationary section.

 - Через пятнадцать минут все страны третьего мира на нашей планете будут знать, как построить межконтинентальную баллистическую ракету. Если кто-то в этой комнате считает, что ключ к шифру-убийце содержится еще где-то, помимо этого кольца, я готов его выслушать.  - Директор выдержал паузу. Никто не проронил ни слова. Он снова посмотрел на Джаббу и закрыл.  - Танкадо отдал кольцо с умыслом. Мне все равно, думал ли он, что тучный господин побежит к телефону-автомату и позвонит нам, или просто хотел избавиться от этого кольца.

Парень загородил ему дорогу. - Подними. Беккер заморгал от неожиданности. Дело принимало дурной оборот. - Ты, часом, не шутишь? - Он был едва ли не на полметра выше этого панка и тяжелее килограммов на двадцать.
