What is a Drilling Jar?
A Jar is a specialized tool used in oil drilling to free stuck drilling tools. It works by storing energy under tension and releasing it instantaneously to generate a powerful shock wave that acts on the stuck drill string, loosening and freeing it. Based on the operating mechanism, jars are main...Read more -
What Are the Common Types of Drill Bits in Drilling Operations?
The drill bit is a key component of drilling equipment. Its main function is to break rocks and form boreholes, and it is also one of the primary drilling tools. The specifications and shapes of drill bits should vary according to different working environments and geographical conditions. During...Read more -
Causes and Solutions to WOB Transfer Loss in Drilling
Concept, Phenomena and Hazards of WOB Transfer Loss Concept: During drilling, excessive friction between the drill string and wellbore wall prevents the weight on bit (WOB) from being transmitted to the drill bit—instead, the entire WOB is consumed by the drill string. This manifests as no pen...Read more -
What is Long Auger Drill and Short Auger Drill?
Long auger drills and short auger drills are two common drilling tools, mainly used for drilling operations in loose formations such as soil and sand-gravel. Their core difference lies in the length of the auger flights and applicable scenarios. I.Long Auger Drill (Full Auger Drill) 1.Wo...Read more -
What to Note in Corroded Tubing Fishing Operations?
In the oil and gas industry, the fishing of corroded tubing is a crucial yet challenging task. As tubing often succumbs to corrosion due to factors like harsh downhole environments, chemical reactions with fluids, and electrochemical processes, its structural integrity weakens, leading to breakag...Read more -
What are the Common Thread Types of Downhole Tools ？
Drill Pipe Thread Types Drill pipe threads connect drill string components and transmit torque, with Internal Flush (IF) and Regular (REG) as the most common types (IF, FH, REG1, Full-Hole FH, XH are rare in tool workshops). Core Differences: IF has 4 threads per inch (TPI, thick threads, small ...Read more -
