API DRILLING JAR FOR OILFIELD
QJ—K type drilling jar while drilling is a fully mechanical jar with integrated upper and lower strikes. It has the advantages of simple structure, short length, convenient maintenance and disassembly.
QJ-A type drilling jar while drilling is also a kind of all-mechanical jar. Its structural features are that the release force can be adjusted on-site, the setting is accurate, and it is easy to disassemble and assemble, which is suitable for drilling while working under various circumstances.
QY—A type drilling jar while drilling is a fully hydraulic type drilling jar while drilling with upper and lower strikes. It has many advantages such as simple operation, large shock force, convenient adjustment, high connection strength, stable performance, safety and reliability, and easy maintenance. This product does not cause false shocks when drilling, drilling, receiving a single or touching the bottom of the well, and its hydraulic delay allows the operator to dynamically adjust the size of the upper and lower strike force. Fully sealed oil bath lubrication helps reduce wear and increase service life. In addition. Its position in the drill string assembly is relatively free, and it can be placed in various positions such as tension, neutral point, and compression. It can meet the needs of drilling operations under various operating conditions such as land and sea.
YJ-A type drilling jar while drilling is also a kind of jar with up and down. It uses the principle of hydromechanics, which overcomes the shortcomings of pure hydraulic jars or mechanical jars. The advantages of both are absorbed. The position in the drill string is relatively free, and it can be placed in various positions such as tension, neutral point and compression, and the operation is simple. Easy to use. The mechanical locking and hydraulic delay work together during the upward stroke. The mechanical locking device can prevent tool wear and false vibration during drilling operations. The locking force can be adjusted at the wellhead. The hydraulic delay action allows the operator to adjust the magnitude of the upward strike force; the downward strike process has only a mechanical effect. Its release force can also be adjusted at the wellhead. In addition. This product has a compact structure and high connection strength. Reliable sealing. Fully sealed oil bath lubrication is beneficial to reduce wear and improve service life. Is an advanced new underground accident handling tool.
The split type drilling jar while drilling includes SS type upper drill while drilling (hydraulic) and SX type lower drill while drilling (mechanical). They can be used together. It can also be used separately in accordance with the needs of downhole operation. It is one of the indispensable tools for drilling operations such as directional wells and complex wells.
CS type super striker is an advanced hydraulic salvage tool. It is compared with the up-drilling device. It has the advantages of simple structure and stable performance. It can be used together with the shock accelerator to obtain a more significant shock effect. It is a new type of upward shock tool in drilling engineering such as petroleum and geological exploration.
DX-A ground striker is a new type of ground shock tool improved. Compared with similar products, it breaks through the limitations of the working principle, overcomes the shortcomings of unstable product release force, and parts are easy to burn to death. The down force can be adjusted at the wellhead at any time. The setting is accurate, safe and reliable.
KX type open hammer and BX type closed hammer are a tool commonly used in drilling and fishing operations. The structure is simple and the work is reliable. It can be saved by the weight of the drill string and the elastic extension of the drill string. The elastic energy creates a strong downforce, and it hits the stuck drill to deal with the downhole accident.
The ZJS type shock accelerator is used in conjunction with the jar, especially in directional wells, horizontal wells or shallow wells with limited drill string elongation, which have deep wells and high frictional resistance. In addition, the shock accelerator can absorb the rebound impact of the drill string after the shock, can protect the tool and drill string, and reduce the drilling cost. It is an advanced card release tool that is safe, reliable, simple to operate and easy to use and maintain.
KYJ-A type air-while-drilling jar is a new type of hydro-mechanical type drilling jar while drilling. Its design and manufacture fully considers some problems that seriously affect drilling, such as high temperature, high torque and corrosion, and is suitable for including underbalance. All drilling operations, including drilling, can also be used for special salvage operations after adjusting the release force. This type of shocker has four remarkable characteristics: first, the upper and lower strikes are integrated, the overall structure is simple, reasonable, safe and reliable; second, the mechanical principle and the hydraulic principle are fully optimized and combined, with simple operation, large shock force, Convenient adjustment, high connection strength, stable performance, easy maintenance, etc. Thirdly, the product will not erroneously vibrate when drilling, starting and drilling, receiving a single or touching the bottom of the product, and its hydraulic delay allows the operator Dynamically adjust the size of the upper force. Fully sealed oil bath lubrication is beneficial to reduce wear and improve service life. Fourth, its position in the drill string assembly is relatively free, and it can be placed in various positions such as tension, neutral point, and pressure, making it suitable for various types of work including land and ocean (in
