摘要:
为解决准噶尔盆地硬脆性页岩地层井壁失稳的问题，在分析准噶尔盆地硬脆性页岩矿物组成与组构特征的基础上，根据多元协同井壁稳定理论，提出了以多尺度致密封堵为核心的协同稳定井壁技术对策，构建了多尺度致密封堵水基钻井液YHDF-1和YHDF-2。矿物组成和组构特征分析结果得知，准噶尔盆地硬脆性页岩地层井壁失稳与“微裂缝–裂隙–孔隙”的多尺度特征密切相关，加强封堵微纳米尺度缝隙，提高抑制页岩表面水化的能力，发挥合理密度钻井液有效应力支撑井壁的作用，才能协同强化稳定井壁。性能评价结果表明，多尺度致密封堵水基钻井液YHDF-1和YHDF-2可耐150 ℃高温，其400 mD砂盘的PPA滤失量分别为17.8和13.2 mL，可使页岩的渗透率降低90%以上。钻井液YHDF-1和YHDF-2分别在准噶尔盆地的D-72井和D-12井进行了现场试验，钻井过程中均未出现井壁失稳现象，试验井段平均井径扩大率均小于10.0%，电测均一次成功。研究和现场试验结果表明，多尺度致密封堵水基钻井液YHDF-1和YHDF-2具有优异的封堵防塌性能，可以解决准噶尔盆地硬脆性页岩地层井壁失稳的问题。
Abstract:In order to solve the problem of wellbore instability in hard and brittle shale formations in Junggar Basin, the characteristics of mineral compositions and structural fabric of shale were analyzed, and the technology strategy with multi-scale tight plugging as the core was proposed according to the multivariate synergistic principle for wellbore stability. Furthermore, water-based drilling fluids (YHDF-1, YHDF-2) with multi-scale tight plugging were developed. From the analysis results of the mineral compositions and structural fabric characteristics, it is known that the wellbore instability of hard and brittle shales was closely related to its multi-scale characteristics of “microfracture–fissure–pore”. Therefore, the wellbore stability could be enhanced by plugging micro-nano scale fractures, improving shale hydration inhibitive ability, and offering effective stress support of drilling fluids with reasonable density. Performance evaluation results showed that YHDF-1 and YHDF-2 drilling fluids could withstand a high temperature up to 150 °C, and their PPA filtration volumes in a 400 mD sand disc were 17.8 mL and 13.2 mL respectively, with the shale permeability reduced by above 90%. YHDF-1 and YHDF-2 drilling fluids were applied in the drilling operation of Well D-72 and D-12 in Junggar Basin, and no wellbore instability occurred during the drilling process. The average well diameter enlargement rate was lower than 10% in all the test well sections, and the electrical logging was achieved successfully at a time. Research and field tests show that YHDF-1 and YHDF-2 drilling fluids exhibit excellent performance in plugging and collapse prevention, and can be used to deal with the wellbore instability of hard and brittle shale in Junggar Basin.
