المقدمة
يلعب مقياس كينلي™، وهو أداة متخصصة تستخدم في صناعة النفط والغاز، دورًا حاسمًا في الحفاظ على سلامة آبار النفط وسلامتها. تم تصميم هذا المقياس متعدد الأصابع لتوفير قياسات تفصيلية لقطر الغلاف الداخلي (ID)، مما يساعد على تحديد المشاكل المحتملة التي يمكن أن تؤدي إلى التسربات، وانفجارات البئر، والتلف البيئي.
مقياس كينلي™: نظرة أعمق
مقياس كينلي™ هو أداة يتم نقلها إلى أسفل البئر باستخدام سلك أو أنبوب ملفوف. يتكون عادةً من أصابع متعددة ذات نوابض تتمدد للخارج، ملامسة جدار الغلاف. يتم تجهيز كل إصبع بمستشعر يقيس بدقة المسافة من محور الأداة المركزي إلى جدار الغلاف.

5. How is the Kinley Caliper™ deployed in a wellbore?
a) It is attached to a drilling rig. b) It is lowered on a wireline or coiled tubing. c) It is pumped down the wellbore. d) It is installed permanently in the casing.
b) It is lowered on a wireline or coiled tubing.
Scenario:
You are an engineer working on a well project. The Kinley Caliper™ data reveals a significant reduction in casing inner diameter (ID) in a specific section of the wellbore.
Task:
Possible Causes: * **Corrosion:** Internal corrosion can eat away at the casing wall, reducing the inner diameter. * **Pitting:** Localized corrosion forming pits on the casing wall can also reduce the overall ID. * **Scale Build-Up:** Mineral deposits can build up on the inner casing surface, reducing the ID. * **External Damage:** Mechanical damage from tools or debris could have caused a dent or deformation reducing the ID. Potential Risks: * **Tubing Hang-Up:** The reduced ID might make it difficult or impossible to run tubing through the well. * **Cementing Issues:** Reduced ID could affect the effectiveness of cementing operations. * **Leakage:** The weakened casing due to corrosion or pitting can lead to leakage. * **Blowout:** In extreme cases, severely compromised casing could lead to a blowout. Actions to Take: * **Further Investigation:** Run additional logging tools like a caliper log, ultrasonic inspection, or a production logging tool to further assess the damage and its extent. * **Well Intervention:** Consider remedial actions like: * **Casing Repair:** Depending on the nature and severity of the damage, a casing repair operation may be necessary. * **Casing Replacement:** In cases of severe corrosion or damage, a replacement of the casing may be required. * **Well Abandonment:** In extreme cases, if the well is considered unsafe or beyond repair, well abandonment might be the only option. * **Risk Assessment:** Conduct a thorough risk assessment to understand the full implications of the reduced ID and plan for safe and effective mitigation.
