摘要:
針對四川盆地巖氣開發過程中出現的套管變形問題,在定量分析了壓裂液浸泡過程中頁巖強度隨時間變化規律的基礎上,建立了頁巖強度折減條件下的套管-水泥環-地層組合體三維數值計算模型,分析了頁巖強度降低對套管變形的影響,并對影響套管變形量的因素進行了分析。計算結果表明:頁巖強度發生折減時,會產生垂向位移,從而導致套管在垂向上產生變形。頁巖強度降低幅度越大,套管變形量越大;隨著巖性界面傾角的增加,套管變形量先線性增加后緩慢增加;增加套管鋼級以及降低徑厚比對于降低套管變形量有一定的效果。
Abstract:
Aiming at the casing deformation in the process of shale gas development in the Sichuan Basin, based on quantitative analysis of the law of shale strength with time during fracturing fluid immersion, the casingcement sheathformation assembly considering the shale strength reduction was established, the influence of shale strength reduction on casing deformation were analyzed, and the factors affecting casing deformation was analyzed as well. The calculation results show that when the shale strength is reduced, vertical displacement will occur, which will cause the casing to deform vertically. The greater the decrease in shale strength, the greater the casing deformation. With the increase of the lithological interface inclination, the casing deformation increases linearly and then slowly. Increasing the steel grade of the casing and reducing the ratio of diameter to thickness have a certain effect on reducing the deformation.
