wireline overshot price

Using a wireline system, core is recovered quickly by retrieving the inner tube directly through the drill string. The rods remin in the hole until the bit needs to be replaced. This has big cost advantages when drilling deep holes for mineral exploration.

The Wireline Releasable Overshot is a slip type overshot used to retrieve a fish lost in the well bore that does not have a conventional fishing neck.

Once latched onto a fish the overshot can be released by jarring downwards provided the overshot has a solid footing upon which the core can be driven against.

The Wireline Releasable Overshot is composed of the top sub, cylinder, nut, main spring, mandrel, auxiliary spring, adapter sleeve, slips etc., simple structure,easy to use.

Overshots are a key component of wireline coring systems. To retrieve the core sample, the overshot is lowered into the hole on a wire cable until it comes in contact with the spearhead point on the head assembly. Positive latching lifting dogs securely attach, and the inner tube assembly is pulled from the hole to retrieve the core. V-lock Overshots Hole Products" V-lock overshots are safe, reliable, fast, and easy to use. The automatic safety feature is designed to reduce the chance of an accidental release. When the inner tube assembly is attached and lifted, the lifting dogs automatically retract into position. No extra manual steps are required to activate the safety feature, thus reducing the potential for human error. Standard Overshots Hole Products" standard overshots feature a manual safety lock pin. Once the core filled inner tube is hoisted above the top of the drill rods the safety lock pin can be inserted through the overshot head and under the spearhead point. This will allow the operator to hoist and remove the core sample from the inner tube.

Overshots are lifting devices used commonly in wire-line drill jobs. The overshot is dropped using a cable into the inner tube assembly where it lifts up the drill rods from the drill holes. Doing so eliminates the need to couple or uncouple rod strings each time the core needs retrieval.

overshots include spare parts of eye bolt, cable swivel collar, thrust bearing, castle nut, cotter pin, grease fitting, cable swivel body, jar staff, jar tube, hex nut 3/4 UNC, washer, nord lock, cap, ezy lock O/shot, spring, ezy lock O/shot, sleeve, ezy lock O/shot, compression spring, ball 11/32”, ezy lock overshot head, lifting dog, plain pin 1/2”*2-1/8”, spring pin 1/4”*2”, locking pin, set screw, 3/8 UNF*3/4 nyloc, locking sleeve.

One variation of the overshots is the continuous tubing model. This type of overshot is fitted with a grapple system that turns 340 degrees and is ideal for catching slick-wall fish. The overshot also provides circulation back to the fish while pulling out the drill rods. Circulation is restored by using a highly pressurized pack-off which is fitted above the overshot.

The second type of overshots is the hydraulic release model. This one is a bit more advanced and uses set-down weight and differential pressure to activate it mechanically. The overshot pumps fluids into the fish and tools below before latching onto them and pulling. This prior fluid injection washes away debris and any other particles from the surface of the fish making latching easy and the grip tighter. The set-down weight and differential pressure mechanism makes this overshot perfect for horizontal fishing projects.

Another popular overshot in drilling projects is the 150 Release overshot. It uses a huge bore with wire-line tools for fishing out parted drill pipes and their collars. The 150 Release overshots come in different strength levels for varied applications in drill sites. On the other hand, the 70 type overshots are used where the 150 release overshot is not applicable. The 70 type overshot is more accurate in pulling out drill rods that are a bit too narrow to be latched with the 150 overshot.

Two other overshots currently in the market today are the Type 10 and Type 20 overshot. The type 10 overshot is specially designed to retrieve tubular fish 2 inches in diameter. This same overshot can also be used for retrieving 1 5/8 inch drill rods as well, but on a much smaller 2 3/8 tube. The type overshot evenly distributes loads on tool and fish thanks to the internal helix construction that is tapered to provide a 360 degree wall contact. For the 20 Type overshot, this one comes in handy when the fish" top is too short for the 10 Type overshot to pull. The 20 Type grapple fastens to the bottom of the tool thus makes this overshot successful for most projects that use short-neck drill rods.

Technology continues to see newer inventions of the overshots being released to perform even more specific jobs with unparalleled accuracy. Other kinds of overshots you will find in the market include the Chinese Standard Wire-line overshot, HQ overshot, WLP overshot, NQ overshot and the WLH overshot.

The Series 10 Sucker Rod Overshot is a small, rugged tool designed for engaging and retrieving sucker rods, couplings, and other items from inside tubing strings.

Series 20 Short Catch Sucker Rod Overshots are designed for conditions when sucker rods, couplings, and other portions of a fish are too short for retrieval with a standard overshot.

The Hydraulic Release Overshot was designed to aid in the recovery of a stuck fish in a horizontal drilling application where normal rotation for release is not obtainable.

The Series 150 Releasing and Circulating Overshot consists of three main external parts: a Top Sub, a Bowl, and a Guide. Internal catch and pack-off parts are determined by the diameter of the fish. Each assembly is designed for a maximum catch diameter.

A Series 160 Side Door Overshot is recommended when fishing for cable tools or conductor lines in cased holes. The side door overshot is run in on tubing or drill pipe.

The dependable Hydraulic Wireline Jar utilizes a hydraulic system that permits controlled jarring in measuring line or stranded wireline operations when electrical continuity below the jar is not required.
