摘要:
四川長寧-威遠國家級頁巖氣示范區開發過程中,套管變形問題突出,嚴重影響頁巖氣開發效益,F場測井數據顯示,斷層滑移引起的套管剪切變形是一類重要的套管變形形態。建立了斷塊滑動引起套管剪切變形的三維有限差分模型,分階段對斷塊滑動進行模擬,并對模型正確性進行了驗證。引入內徑的凈減小量的概念表征套管變形程度,對套管鋼級、套管壁厚、固井水泥彈性模量和水泥環厚度進行了敏感性分析。結果表明:增大套管鋼級、加厚套管壁厚、降低固井水泥彈性模量、增大水泥環厚度都能減輕套管變形。前兩種方法可以增大套管抵抗變形的能力,但效果不佳;后兩種方法用“以柔克剛”的方法吸收斷塊滑移的影響,進而有效減輕套管變形。該研究成果對解決套管變形具有一定的理論指導意義。
Abstract:
Casing deformation has become one of the most critical issues for the shale gas exploitation in the ChangningWeiyuan demonstration area, Sichuan province, which adversely affects the economic development of shale gas. Field data shows that casing shear deformation caused by hydraulic fracturing induced fault sliding is the most common form. In this work, the threedimensional finite difference model of casing shear deformation caused by block sliding is established. Then the block sliding procedure is simulated in stages after the model is calibrated. The concept of the net reduction of the inner diameter was introduced to characterize the degree of casing deformation, and sensitivity analysis was performed on casing steel grade, casing wall thickness, elastic modulus of cement, and thickness of cement sheath. The results show that the methods of increasing casing steel grade, thickening casing wall, reducing elastic modulus of cement, and increasing cement sheath thickness can alleviate casing deformation. The former two methods can promote the deformation resistance ability of casing, but the effect is limited. While the latter two methods can decrease the deformation resistance ability of casing by absorbing the effect of block sliding, thereby effectively reduce casing deformation. The research results have certain theoretical guiding significance for solving casing deformation.
