CHIP RESISTANT BUTTONS FOR DOWNHOLE TOOLS HAVING SLIP ELEMENTS |
摘要 |
A slip element installable about a downhole tool apparatus for use in anchoring a downhole tool in a wellbore comprising the slip element having at least one slip button made of a metallic-ceramic composite material comprising an effective percentage by weight of a preselected titanium compound whereby the slip button is resistant to chipping upon setting yet has favorable drillability characteristics upon drilling the downhole tool from a wellbore. The slip element may include at least one slip element made of a non-metallic material such as a laminated non-metallic composite material. Preferably at least one slip button is made of a metallic-ceramic composite material comprising less than about 75% by weight of titanium carbide having a density ranging between about 5 to 7 grams per cubic centimeter. Furthermore, the subject slip button is cylindrically shaped and is installed in at least one slip element at a preselected angle and extends outwardly at a preselected distance from a face of the slip element.
