摘要:
API 5C3未考慮套管的制造工藝及缺陷對套管抗擠強度的影響,已不能準確地預測套管實際抗擠強度。API/ISO工作組針對API 5C3存在的不足,修訂了現行API 5C3標準,給出了含制造缺陷的抗擠新模型,大大提高了套管強度計算的科學性。研究中發現,ISO抗擠新模型并不適合所有壁厚段套管強度的計算,為此,在研究和評價ISO新抗擠模型的基礎上,提出了考慮制造缺陷的抗擠強度計算新模型。通過與ISO/TG提供的上百個實物擠毀數據對比驗證,本文所給出計算式的計算精確度明顯好于API 5C3擠毀公式及ISO新模型,為套管強度的設計提供了新的參考依據。
Abstract:
The influence of manufacture technology and manufacturing imperfections on casing collapse resistance strength is not included in API 5C3 standard, so the actual casing collapse resistance strength cannot be predicted accurately by API 5C3 standard. API/ISO working group revised the current API 5C3 standard and proposed the new collapse resistance strength model with manufacturing imperfections, which upgrades the casing strength calculation accuracy significantly. The study on the ISO collapse resistance new model disclosed that it could not be used to predict the collapse resistance strength for all casing thickness. On the base of ISO collapse resistance new model, a new formula for predicting the casing collapse resistance strength was presented. Numerical and experimental comparisons show that the predictive values calculated by the new formula were proper and reliable, and the calculation accuracy is higher than that of API 5C3 standard and ISO new model. It supplied a new reference in casing designs.
