Buy & Import Derun Drilling Jar from Derun Energy Co., Ltd. - Wholesale Supply

The Derun Drilling Jar is a mechanical, non-explosive tool designed to deliver upward impact force to free stuck pipe or retrieve downhole equipment. It operates via a sliding sleeve mechanism that stores energy during tension and releases it as a sharp blow, making it essential for well maintenance and fishing operations in oil and gas drilling.

The tool is constructed from high-strength alloy steel, typically AISI 4140 or equivalent, with a hardened working surface to resist wear under repeated impacts. Standard sizes range from 3.5 to 5.5 inches in diameter, with stroke lengths of 4 to 8 inches. These dimensions align with industry-standard fishing jars used in deep well applications and are compatible with most rig top drives and kelly bushings.

Buyers include offshore drilling contractors, well service companies, and geothermal operators in Southeast Asia, the Middle East, and Latin America. The tool is shipped in reinforced steel crates with internal foam padding to protect the internal mechanism. Trade terms include FOB Qingdao or CIF destination, with payment via T/T or L/C. MOQ is typically one unit, but bulk discounts apply for orders of five or more.

Frequently Asked Questions About Derun Drilling Jar from Derun Energy Co., Ltd.
Stroke length typically ranges from 4 to 8 inches, depending on the model. A longer stroke increases impact energy but requires more top drive tension. Buyers should specify required stroke based on stuck pipe depth and string weight, as mismatched stroke reduces effectiveness.

Sourcing Derun Drilling Jar from Derun Energy Co., Ltd. - China Import Guide

Verify the material grade and hardness of the striker and housing before purchase. Request a material certification and load test report showing the tool was tested to 1.5x its rated capacity. Do not accept tools without documented impact testing, as internal failure can cause serious downhole incidents.

Lead time is typically 25 to 40 days after order confirmation. Confirm Incoterms - FOB Qingdao is standard - and clarify responsibility for marine insurance. Payment terms are usually 30% advance, balance against shipping documents or L/C at sight. Ensure the supplier provides a packing list and export declaration in English.

Conduct a pre-shipment inspection for surface cracks, thread integrity, and smooth operation of the sliding mechanism. Use a torque wrench to simulate tension and observe jar function. Retain a sample for lab analysis if operating in high-temperature or corrosive wells. Always request a certificate of conformity and test records before accepting delivery.
