overshot packer made in china

Fishing tool is a special fishing drilling tool used to retrieve fallen objects from the borehole. At any stage of the operation, the drill rig operator will encounter unexpected situations, such as falling drill string, stuck pipe, missing drill bit, etc. The equipment that falls into the well is called "fish" or "trash", and the tools used to remove the equipment are called "fishing tools." Sometimes it may be necessary to use "fishing tools" to retrieve older wellbore equipment, such as packers, liners, tubing, or any stuck objects in the well. The drilling tools for fishing must be retrieved from the borehole in order to continue drilling operations.

Overshot is a very common fishing tool. The main fishing object is a smooth tube fish, which belongs to the external fishing type (i.e. catching the external surface of the fish).

Taper tap and die collar are common fishing tools for fishing the inner hole of the string. They are used for fishing the inner hole with holes such as tubing, drill pipe, casing milling pipe, packer, water distributor, etc. It is made of high-quality alloy steel and especially heats treated. It has the advantages of high strength, high toughness, and simple buckle making.

The RedSeal Dual Overshot Packer has been developed to provide a dual seal barrier in surface drilling systems used on jack-up and platform applications.

The RedSeal Dual Overshot Packer has been developed to provide a dual seal barrier in surface drilling systems used on jack-up and platform application. The system provides the operator with a primary and secondary seal system to mitigate potential environmental spills.

The system has been developed with a similar design philosophy to the RedSeal Packer system developed for drilling riser telescopic joints but does not include a facility for refill of the packer online as the seal element is a static seal and not subject to the dynamic motion associated to the RedSeal Packer system. Physically the RedSeal Dual Overshot Packer is shorter than traditional single packer systems allowing the system to be utilised in riser systems where stack-up heights are critical.

RedSeal Dual Overshot Packer can be supplied with a dedicated control system to monitor seal actuating pressure and (upon actuating pressure loss to primary seal element) switch automatically to the secondary seal, thereby minimising any environmental impact.

The Retrievable Bridge Plug(RBP) is a high-pressure packer style bridge plug used for multiple selective zone treating and testing operations. The RBP is designed to set in tension or compression, which makes it ideal for shallow applications to test wellhead for deep, high-pressure applications. The plug is designed with a large internal by-pass to prevent swabbing when running and retrieving. The by-pass closes during the setting of the plug and opens prior to releasing the upper slips to equalize pressure when unsetting.

Oil well completion tools include: Subsurface safety valve, wireline retrievable subsurface safety valve, single string production packer, dual strings production packer, ESP packer, mechanical set packer, permanent packer, compensation device, bridge plug, sliding sleeve, nipples etc.

Parveen is specialized in design and supply of Completion tools like Production packers Bridge plugs and their accessories by using the well established quality management system that meets API and ISO standards.

Packer is a mechanical device with a packing element installed in a designed receptacle, used for blocking fluid (liquid or gas) communication through the annular space between conduits by sealing off the space between them”.

A Packer is usually set just above the producing zone to isolate the producing interval from the casing annulus or from producing zones elsewhere in the wellbore.

Parveen offers a complete line of production packers and accessories — from standard packers to specialized designs for the most hostile environments. Our packers are designed as per API 11 D1 Validation Grade V6-V0 and Quality Control Grade Q3-Q1.

In addition to providing a seal between the tubing and casing, other functions of a packer are as follows:Prevent downhole movement of the tubing string, generating considerable axial tension or compression loads on the tubing string.

Mandrel is a main component of a packer that contains the end connections and provides a conduit through the packer. It is subjected to direct exposure to flowing fluid hence its material selection is a very vital decision. Primarily used materials are L80 Type 1, 9CR, 13CR, 9CR1Mo. For more corrosive and sour services Duplex, Super Duplex, Inconel are also used as per the requirement.

The slip is a wedge-shaped device with wickers (or teeth) on its face, which penetrate and grip the casing wall when the packer is set. There are different types of slips designs are available in packers like dovetail slips, rocker type slips bidirectional slips depending upon packer assembly requirements.

The cone is beveled to match the back of the slip and forms a ramp that drives the slip outward and into the casing wall when setting force is applied to the packer.

Packing element is the most important part of any packer and it provides the primary sealing purpose. Once the slips have anchored into the casing wall, additional applied setting force energizes the packing-element system and creates a seal between the packer body and the inside diameter of the casing. The primarily used element materials are NBR, HNBR or HSN, Viton, AFLAS, EPDM etc. Most popular element system are permanent single element system with expansion ring, three piece element system with spacer ring, ECNER element system, Spring loaded element system, Fold back ring element system.

Lock ring play a vital role in packer’s function. The purpose of a lock ring is to transmit axial loads and allow unidirectional motion of packer components. The lock ring is installed into the lock ring housing and both move together over the lock ring mandrel. All setting force generated due to tubing pressure is locked into packer by lock ring.

As the name implies Permanent Packers cannot be retrieved, but can be destructively removed (i.e. milling).The permanent packer is fairly simple and generally offers higher performance in both temperature and pressure ratings. In most instances, it has a smaller outside diameter (OD), offering greater running clearance inside the casing string than do retrievable packers. The smaller OD and the compact design of the permanent packer help the tool negotiate through tight spots and deviations in the wellbore. The permanent packer also offers the largest inside diameter (ID) to make it compatible with larger-diameter tubing strings and monobore completions.

PARVEEN Model D Production Packers provide excellent clearance for run-in while the PARVEEN Model “F” Production Packers offer a larger seal bore. The two models carry different pressure ratings noted later in this document. PARVEEN Packers are designed for differential pressures up to 10,000 PSI.
