What are the main systems of oil drilling RIGS?
1.Lifting system: In order to lift and lower the drilling tools, run casing, control the drilling weight, and feed the drilling tools, the drilling tools are equipped with a lifting system. The lifting system includes winches, auxiliary brakes, cranes, traveling blocks, hooks, wire ropes, and var...Read more -
What are the causes of high-pressure corrosion in petroleum machinery?
1. Polysulfides in petroleum cause high-pressure corrosion of petroleum machinery Most of the petroleum in our country contains a lot of polysulfides. During the oil extraction process, petroleum machinery and equipment are easily corroded by the polysulfides in the petroleum when they come into ...Read more -
Stabilizer Blade Hardfacing Type
To meet a variety of drilling conditions, we have 6 types of hardfacing to choose from. HF1000 Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling. HF2000 Trapezoidal tungsten carbide in...Read more -
Extension and development direction of Mud Motor
1. Overview Mud Motor is a positive displacement downhole dynamic drilling tool which is powered by drilling fluid and converts liquid pressure energy into mechanical energy. When the mud pumped by the mud pump flows through the bypass valve into the motor, a certain pressure difference is formed...Read more -
What is the main function of the blowout preventer?
In oil and gas drilling construction, in order to safely drill through high-pressure oil and gas layers and avoid out-of-control drilling blowout accidents, a set of equipment – a drilling well control device – needs to be installed on the wellhead of the drilling well. When the press...Read more -
The functions and classification of hydraulic cement retainers
The cement retainer is mainly used for temporary or permanent sealing or secondary cementing of oil, gas, and water layers. The cement slurry is squeezed through the retainer into the well section of the annulus that needs to be sealed or into the cracks in the formation, pores to achieve the pur...Read more -
What are the classifications and applications of oil drilling hoses?
Oil drilling hose is a special pipeline device used in oil field drilling operations. It undertakes the important task of transporting media such as drilling fluid, gas and solid particles, and is an indispensable part of the oil drilling process. Oil drilling hoses have the characteristics of hi...Read more -
Causes and solutions of drilling sticking
Sticking, also known as differential pressure sticking, is the most common sticking accident in the drilling process, accounting for more than 60% of sticking failures. Reasons for sticking: (1)The drilling string has a long static time in the well; (2) The pressure difference in the well is larg...Read more -
Maintenance measures for drilling machinery and equipment
First, during daily maintenance, attention should be paid to keeping the surfaces of mechanical and petroleum machinery equipment dry. During normal use of these equipment, some sediments will inevitably be left behind. The residue of these substances will increase the wear and tear of the equipm...Read more -
Drilling sand bridge stuck and accident treatment
Sand bridge stuck is also called sand settling stuck, its nature is similar to collapse, and its harm is worse than sticking stuck. 1.The reason of sand bridge formation (1) It is easy to occur when drilling with clean water in soft formation; (2)The surface casing is too little, and the soft s...Read more -
Why do we need to use casing centralizer?
The use of casing centralizer is an important measure to improve the quality of cementing. The purpose of cementing is twofold: firstly, to seal off the well sections that are prone to collapse, leakage, or other complicated conditions with casing, so as to provide a guarantee for the continuatio...Read more -
Method of checking balance of pumping unit
There are three main methods to check the balance of pumping units: observation method, time measurement method and current intensity measurement method. 1.Method of observation When the pumping unit is working, directly observe the start, operation and stop of the pumping unit with eyes to judge...Read more
