摘要

摘要: 下钻速度通过影响井筒有效压力而引起地层裂缝宽度变化，造成井漏隐患.结合下钻井深、钻具组合、地层岩石物理参数、钻井液性能，考虑下钻速度和钻井液可压缩系数等参数，建立了井筒压力瞬变与裂缝变形耦合作用的数学模型.模型采用有限元有限体积耦合方法进行求解，并利用四川盆地威远区块自X井龙马溪组硬脆性页岩地层数据验证了其可靠性.结果表明： ① 下钻速度从0.5 m/s增加到2.0 m/s时，井筒压力从86.0 MPa增加到106.6 MPa，裂缝宽度从0.478 mm增加到0.881 mm. ② 裂缝宽度随下钻井深、钻柱环空比的增加而增加.下钻速度为0.5 m/s时，下钻井深从1 500 m增加到5 500 m，裂缝宽度从0.432 mm增加到0.478 mm；钻柱环空比从0.59增加到0.65，裂缝宽度从0.463 mm增加到0.487 mm.③ 下钻速度从0增加到1.5 m/s，下钻井深为1 500 m时，裂缝宽度从0.4 mm增加到0.474 mm；下钻井深增加到5 500 m时，裂缝宽度从0.5 mm增加到0.624 mm；裂缝宽度随下钻速度增加而增加，下钻速度超过1.0 m/s后，增加趋势更加显著；且随着下钻井深增加，裂缝宽度的增加幅度越大.本研究为优化下钻操作参数提供了理论依据，对预防钻井过程中的井漏事故具有重要指导意义.

Abstract: The trippingin speed affects the wellbore effective pressure, leading to changes in formation fracture widths and posing a risk of mud loss. The trippingin speed and drilling fluid compressibility, along with the well depth, the bottomThe trippingin speed affects the wellbore effective pressure, leading to changes in formation fracture widths and posing a risk of mud loss. The trippingin speed and drilling fluid compressibility, along with the well depth, the bottomhole assembly, the formation petrophysical parameters, and the drilling fluid properties were incorporated to build a mathematical model coupling wellbore pressure transients and fracture deformation. The model was solved with the finite elementfinite volume coupling method and validated with data from the hardbrittle shale formation of the Longmaxi formation in the Zi X well of the Weiyuan Block in the Sichuan Basin. The results show that, i. when the trippingin speed increase from 0.5 m/s to 2.0 m/s, the wellbore pressure will increase from 86.0 MPa to 106.6 MPa, while the fracture width will rise from 0.478 mm to 0.881 mm. ii. Bigger fracture widths go with greater trippingin depths and higher drill string annular ratios. At a trippingin speed of 0.5 m/s, when the tripping depth increases from 1 500 m to 5 500 m, the fracture width will rise from 0.432 mm to 0.478 mm; when the drill string annular ratio increases from 0.59 to 0.65, the fracture width will rise from 0.463 mm to 0.487 mm. iii. As the trippingin speed increases from 0 to 1.5 m/s, at a tripping depth of 1 500 m, the fracture width will rise from 0.4 mm to 0.474 mm; at a tripping depth of 5 500 m, the fracture width will rise from 0.5 mm to 0.624 mm. Bigger fracture widths go with higher trippingin speeds, and the rising trend will be more pronounced once the trippingin speed exceeds 1.0 m/s; further, this rise becomes more pronounced with greater tripping depths. This study provides a theoretical basis for optimizing trippingin operation parameters and offers an important guidance for preventing mud loss incidents during drilling.hole assembly, the formation petrophysical parameters, and the drilling fluid properties were incorporated to build a mathematical model coupling wellbore pressure transients and fracture deformation.
