0000009889 00000 n We are glad to introduce this refreshed version of the site, with improved accessibility, updated content and new features. This additional strength provides the required torque for drilling to extended depths or in more demanding environments. I determine the refaceability of a connection by referencing the pin or box bench mark and if a bench mark is not present (some machine shops dont re-apply bench marks when recutting) I measure the pin length or box counterbore length to assess refaceability. I won't be talking about connections for casing or tubing. Also at the time, API took the most popular older connections, gave them a new thread and new name and stuck them into the lineup. The longest & major section of the Drill String Componentsis the Drill Pipe. They were originally a proprietary product of Hughes Tool Company and are easily recognized by their shallow 90 degree thread angle. hVmO0+ !2&4*-cVP (-KB1!K|>q@5c4fw7;/*;>r3xg|bzx?d65lEvE.qegi6+l[d@ZHk]+'wX#H]K-Z21F]*J^ Cleaning and Transporting Your Scanner. %PDF-1.5 Team uniforms and spirit wear. % All rights reserved. 0000088212 00000 n Yet, this applies to the pipe, and NOT to the connections.

At Odfjell Well Services we constantly hear from people who ask us why certain drill pipes don't go together. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network. l Drill Pipe. Our DS is interchangeable with the following API thread connections: DS38 NC38DS40 NC40DS46 NC46DS50 NC50DS55 5 1/2 FH High TorqueConnections DT Connections DT connections are double shoulders connections with API thread pro les. This allows smoother fluid flow with minimized turbulence and energy loss inside the connection. Example 1) I inspected the drilling tools including drill collars, hevi-wate drillpipe, subs and miscellaneous directional tools on a rig drilling horizonal wells in the Edson and Hinton area between August of 2015 to December of 2020. Examples of this are Vam Eis, DSTJ, GPDS, etc. The wide range of connections naturally brings up the question about compatibility. Through design optimization and balancing of stresses, the connections enhanced fatigue resistance eliminates the need for cold-rolling drill pipe connections. Rejected a total of 12 subs (mostly saver and drill thru subs), 3 drill collars, and 5 hevi-wate drillpipe for excessive thread or seal damage. The minimum strength can be converted to a more usable strength in pounds by multiplying the minimum yield in psi by the cross-sectional area of the metal. Every day, the oil and gas industrys best minds put more than 150 years of experience to work to help our customers achieve lasting success. It is for reference only and should not be construed as a recommendation. - Ensure 360 DEGREES of coverage of the threads and torque shoulders. Example2) I inspected the drilling tools on this rig drilling horizontal wells in the Edson and Hinton area between August of 2017 to April of 2021. They are the load flank and the stabbing flank. 35 likes. 58 0 obj <>stream Uniform wear and a minimum wall thickness of 80% of original wall thickness.

That is a refacing rate of under 6% and reject rate for machine shop recuts due to mechanical damage of under 2%. With the same outside diameter and inside diameter, our DT connection torque capacity is about 40% higher than the API connection. RSC's come in two sub-categories: Study the schematic for drill pipe tool joints below to gain a better understanding of what we are talking about: > Read also: How to choose the right drill pipe. Standard makeup torques in PAC drill collars cause a pin neck tensile stress of 87,500 psi, compares to 62,500 psi in a similar sized NC connection. 0000018152 00000 n Tool joint upset type is a part of the drill pipe specifications (specs). In general, D/Ps joints are available in three length ranges: API Drill Pipe Specifications (specs) is generally described 6 items. Although similar to other API connections, these connections incorporate an internal secondary torque shoulder. They offer good clearance, but often at the price of alarmingly low tensile and torsional capacity. 5,295 were here. All Full Hole connections were made obsolete by API in 1968, to be superseded by NCs. In addition, monitoring of the first 108,000 connection inspections showed Delta requires 3.1 times fewer recuts than XTmeaning cheaper repair bills, fewer pipe movements for repair, and simply less pipe needed as contingency. )2ah2B0vYL]7:`P2pwnPUAXeR=TXK;:%-YyGK~=fOvmK3Jtb%(7nlJ`sy4%=[ In all the years I have inspected drilling tools I have never seen a seal that has been filed cause washouts. <>>> Since downhole stress can be additive to makeup stress, PAC connections are that much closer to failure even as they pass through the rotary.
