The drilling jar supplied by Dongying Lake Petroleum Technology co.,ltd is a downhole stuck‑free tool designed for use with drill strings in challenging wells. It incorporates a ZSJ up‑jar that operates by hydraulic pressure and a ZXJ down‑jar that relies on a mechanical friction mechanism. The up‑jar’s impact force can be varied by adjusting the hydraulic load, while the down‑jar is set to a fixed load before deployment and cannot be readjusted in‑hole. Both jars are engineered to work together or independently, providing flexibility for directional, complicated or deep‑well operations.
The jars are fabricated from high‑strength carbon steel, typically grade 4140, to withstand high impact energies. Industry practice places the impact energy of similar jars around 3000 J, with operating pressures between 10 and 30 MPa. Standard dimensions are about 120 mm in diameter and a weight near 45 kg, which fits the common drill‑string size range. They comply with API RP 7G specifications, a recognised standard for downhole tools.
Oilfield service companies use these jars to release drill‑string blockages and to protect equipment during drilling of directional and deep wells. Buyers should confirm the exact maximum load rating and compatible drill‑string dimensions with the supplier before placing an order. Trade terms such as MOQ, Incoterms and payment conditions are not disclosed in the listing and must be negotiated directly. Shipping is typically arranged in wooden crates, one jar per crate, and the supplier’s response rate is currently 0 percent, so prompt follow‑up is advisable.

Sourcing Drilling Jar from Dongying Lake Petroleum Technology co.,ltd - China Import Guide
Buyers should obtain the exact maximum jarring load rating and confirm compatibility with their drill‑string dimensions. Request the supplier’s technical data sheet that lists hydraulic pressure limits and impact energy. Verify that the jars meet API RP 7G and that the material grade matches high‑strength carbon steel. Ensure the unit’s dimensions fit the intended wellbore size.
Logistics: typical shipment in wooden crates, one jar per crate. Incoterms, lead time and payment conditions are not disclosed and must be agreed directly. Confirm whether the supplier can arrange freight forwarding from the port nearest Dongying City and whether they accept letters of credit or advance payment.
Quality checks: arrange third‑party inspection to verify material grade, impact energy and hydraulic load adjustment range. Request test reports for API compliance and for the actual jarring force. Ensure that the inspection certificate and packing list accompany the freight to streamline customs clearance.
