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 -
How to select and maintain oil drill pipe?
Oil drill pipe is an important component in oil drilling, and its selection and maintenance are critical to the success and safety of drilling operations. The following will introduce several key points in the selection and maintenance of oil drill pipes. Selection of oil drill pipe 1.Material se...Read more -
How to use torque anchors correctly?
Torque anchor is a new type of special anchor for screw pump anti-separation. When used in the well, the anchor does not need to be lifted up or down to lower the seat seal. It has good centering performance and keeps the oil pipe and sucker rod in a vertical downward state to avoid eccentric wea...Read more -
Classification of oil and gas well increase production techniques
Oil and gas well increase productio technology is a technical measure to improve the production capacity of oil wells (including gas wells) and the water absorption capacity of water injection wells. Commonly used methods include hydraulic fracturing and acidification treatment, in addition to do...Read more -
What is Thru-tubing Inflatable Bridge Plug technology?
Technology introduction: During the production process, oil and gas wells need to perform section plugging or other workover operations due to the increase in crude oil water content. The past methods...Read more
