استخدام أدوات ضبط الجودة في صيانة معدات آلات حفر آبار النفط

Abstract EN

This research contains practical applications of some quality control tools in maintaining drilling rigs equipment.

First a statistical study of mechanical breakdowns for four drilling rigs during one and half year have been done, and charts of these breakdowns have been drawn, comparison between each two rigs which have the same type and capacity was made.

After that, Pareto charts have been drawn to determine the equipment which has the biggest ratio of breakdowns.

Then an Ishikawa fishbone diagram has been drawn for the most important equipments which have been determined by Pareto charts to focus on the most iterative and effective breakdowns, thus, determine their reasons.

A modern computerized programs have been used in drawing these charts.

Furthermore, all failures that had caused breakdowns have been programmed according to date and duration of breakdowns then charts of these breakdowns have been drawn using Excel Program.

QI macros 2009 program has also, been made for drawing all charts related to quality (Pareto chart, Ishikawa fishbone diagram).

Finally, obtained data have been analysed by applying quality control tools.
