Title: An automatic control system and method for bottom hole pressure in the underbalance drilling
Inventor: YANG CHUNGUO
IPC: E21B21/08
Filed: 2004-10-28
Abstract: This invention provides an automatic control system and method fox bottom bole pressure (BHP) in the underbalance drilling. It relates to a computer automatic control technology. The automatic control system according to the invention includes a processing module for the BHP based on the mechanisms of hydraulics. The BHP in the underbalance drilling is calculated from the acquired standpipe pressure (SPP), the calculated circulating pressure loss in the drilling tools, drill bit pressure drop and the fluid column pressure in the drill string. The resulting BHP is then compared with the set pressure value of the system. In case that the BHP is higher or lower than the set pressure, an instruction to regulate throttle valve opening will be issued in order to bring the BHP back to the set pressure range and complete BHP monitoring and control, The automatic control system and method according to the invention enable real-time tracking of the changes in BHP and achieve accurate and timely adjustment and control of BHP. The automatic control system and method improve the level of automation in the underbalance drilling process, and also enhance the reliability and safety in the underbalance drilling operation, which have wide foreground for application.

Patent CA-2489696-A1 (CA)
Inventor: KIELLAND PETER
IPC: B65B25/00
Filed: 2004-12-20
Abstract: A folded paper label for insertion inside the transparent cover of a "Slimline Jewel Case" containing a digital "Compact Disk" ("CD"). The label is adapted for displaying printed text though the case's transparent hinged edge by means of a spine panel, folded at right angles to the label's larger face panel, thereby permitting said label to fit inside of said cover with its spine panel visible through said edge. A pair of corner cutouts formed through the label's main and spine panels may be provided for improved clearance around the cover's hinges.  To enable a standard office printer to fully exploit the label's small spine panel, a full-sized "carrier page" may be provided for transporting said label through the printer while avoiding said printer's inaccessible hardware margins. A patch of low-tack, repositionable adhesive on said carrier page is used to temporarily affix it to the blank label and a coordinated word processing template is used to compose and print label text right up to the paper's edge. In another embodiment, the label information is printed directly onto the label without using a carrier page.  In this simpler embodiment, the software template exploits the hardware margin characteristics of certain printers by positioning the label's spine portion towards the printer's accessible center portion, thereby enabling text to print flush to the label's edge. In yet another embodiment, a foldout portion adjacent to the label's spine portion serves as a spacer for distancing said spine portion at a known distance from the printer's hardware margin.
