Dezhou Jingmei Petroleum Machinery Co. Ltd., located in the Economic Development Zone of Dezhou, Shandong, China, manufactures the QYZ type hydraulic drilling jar. The product family includes three models - Qyz121, Qyz165 and Qyz203 - each featuring an upward and downward jarring mechanism that releases stuck drill stems. According to the supplier data, the jars deliver a maximum working load of 635 kN and a maximum tensile load of up to 3 835 kN for the Qyz121 model. Stroke lengths range from 2‑1/4 in (Qyz121) to 3 in (Qyz203).
All jars are fabricated from a sulfur‑resistant alloy, a material choice that improves durability in H₂S‑rich environments common to oil‑field work. The connection size is a standard 3‑inch NC thread, allowing compatibility with typical drill string components. Typical hydraulic pressure rating for jars of this class is around 200 bar, and a conventional unit weighs roughly 100 kg, providing a balance of strength and handling ease. The design prioritises stable operation, ease of maintenance and safety during jarring cycles.
The hydraulic jars are suited to a range of well‑conditioning operations, including stuck‑pipe recovery and pressure‑testing in vertical and deviated wells. Primary buyers are drilling contractors and service companies that require reliable jarring tools for offshore and on‑shore projects. The supplier lists a minimum order of one piece, offers custom packing per the buyer’s request, and can supply up to 600 sets per year; however, buyers should confirm lead times, Incoterms and payment conditions directly with the manufacturer.

Before placing an order, verify the model number, maximum working and tensile loads, and the material grade against the technical data sheet provided by the supplier. Request a material test report for the sulfur‑resistant alloy and confirm that the 3‑inch NC connection matches your drill string specifications. These checks reduce the risk of incompatibility during well operations.
Logistics should be clarified with the manufacturer: ask for the expected lead time, preferred Incoterms (e.g., FOB Qingdao or CIF Shanghai) and the payment method they accept. Because the supplier lists a minimum order of one piece, discuss bulk packaging options if you require multiple jars, and obtain a detailed quotation that includes freight, insurance and handling charges.
Arrange for a pre‑shipment inspection by an independent third‑party agency to verify dimensional tolerances, thread integrity and material certification. Request the shipment documents - test report, material certificate and conformity declaration - before the container departs. Upon arrival, conduct a visual check and, if possible, a functional test to ensure the jar operates within the specified load and stroke parameters.
