CSC Production Square Kelly and Hexagonal Kelly

Kelly is located in the top of the drill string, with square and hexagonal. In rotary drilling, when it's drilling, kelly connected with square bushing and rotary bushing, transfer the ground rotary torque to drill pipe and to drive the drill bit, bearing the weight of drill string. In the drilling of the turbine and drilling motor, the weight of drill string and the counter torque are supported

What are the different types of OCTG pipes?

OCTG is an acronym for Oil Country Tubular Goods. OCTG is tubing used in oil and gas production. The pipeline is used to produce oil and gas onshore and offshore. Oil Country Tubular Goods is a range of rolled metal products such as drill pipe, casing and tubing, Pup joints, connections and fittings for oil and gas production activities. These OTCG products are manufactured according to the specifications set by API (American Petroleum Institute)

What are the production steps for casing and tubing pup joints?

Introduction and function of drill pipe

Drill pipe is the hollow, thick-walled pipe that transmits drilling fluid and torque through the wellbore to the drill bit on the rig

OCTG Tubular API-5CT EUE Tubing Pipe introduction

API-5CT EUE Tubing Pipe The API external-upset-end (EUE) tubing pipe is broadly used due to the fact that is a good, serviceable interconnection in the majority of wells.

Casing Coupling and Tubing Couplings specifiction

Couplings are used to hold the neighboring joints together during axial tension or compression.The common oilfield API-5CT casing couplings include J55, K55, N80 and P110 in accordance with API 5CT/5B, can be classified as STC (short thread), LTC (long thread) BTC (buttress thread) and premium connections.

What is the difference between J55, K55, N80-1, N80Q, and P110 of commonly used oilfield API-5CT casing steel grades?

Commonly used oilfield API-5CT casing steel grades are J55, K55, N80-1, N80Q, P110. Casings are mostly used in oil well drilling. According to the API-5CT standard, pipes can be divided into STC (short thread), LTC (long thread) and BTC (support thread) and their joints. Oilfield casing is placed in the wellbore and held in place to prevent subterranean formation and wellbore collapse and also to allow drilling mud to circulate and be extracted. Sleeves are typically manufactured with external dimensions ranging from 114.3mm to 508.0mm.
