CASING PATCHES. Operation

Transcription

1 Overview Logan High Pressure Type L Packer Type Casing Patches are designed to engage and seal off a properly prepared casing string. The Casing Patch design leaves the operator with a casing string that has a fullbore internal diameter. Logan High Pressure Type L Packer Type Casing Patches will not restrict the bore of the casing and are available in popular casing sizes from 4-1/2 to 13-5/8 inches OD. Larger size Casing Patches are available upon request. The Logan High Pressure Type L Packer Type Casing Patches are available in 7,000, 10,000, and 12,000 psi working pressure ratings. All are designed to seal both internal and external pressure. Logan also manufactures a High- Pressure Casing Patch that is rated at 15,000 psi working pressure. Lower and higher-pressure Casing Patches of this design are available upon request. Logan High Pressure Type L Packer Type Casing Patches are available with or without five-foot extension subs. Construction The tool is very similar in design and construction to the Logan Series 150 Overshot. A Top Sub, Bowl, and Guide make up the outer components of the assembly. A Basket Mill Control Packer, Basket Grapple, four Logan Type L Packers, Packer Protector, and Shear Pins are components inside the assembly alloy steel is used in the manufacture of the major load bearing components. The Type L Packers are made of a blend of hydrogenated nitrile (HBNR) material that is compatible for service with most drilling and completion fluids, and is resistant to gas invasion and abrasion. They are rated at 275 F (dry, with no circulation) and at 325 F (with partial circulation). Operation Proper preparation of the casing to be patched is important to the success of the Logan High Pressure Type L Packer Type Casing Patch. The casing should be washed over to remove scale and splits and the pipe sized for a uniform sealing surface. The properly assembled Casing Patch should be lowered to the top of the fish. Slow rotation combined with slow lowering is important to the operation of the assembly. Once the fish has entered the Casing Patch, slowly slack off the rotation until the Packer Protector bottoms out against the shoulder in the Top Sub and the casing is fully engaged in the patch. Apply a tensile load to the Casing Patch to set the grapple. The slips should then be set on the running string. To test the patch, slowly engage the mud pumps so as not to slug the packers with excessive pressure. Then bring the pressure up to the desired test pressure.
