- 摘要:
将钻井平台产生的废弃水基钻井泥浆进行高效、无害化处理对生产过程至关重要。以四川蓬深X井钻探作业中产生的废弃水基钻井泥浆为研究对象,进行化学强化固液分离研究。通过实验研究系统探讨了单一试剂、两种或三种试剂复配的破胶剂对泥浆固液分离效果的影响。在单因素实验中,单独加入石灰CaO的固液分离效果最佳,用量为0.8 g/50 mL;在两种试剂协同作用的双因素实验中,硫酸亚铁FeSO4和CaO的用量应控制在0.6 g/50 mL;在三种试剂复配的正交实验中,影响分离效果的因果主次顺序为FeSO4>CaO>PAC。研究发现,最优化条件下,PAC、FeSO4和CaO的配比为0.3∶0.4∶0.15,所得的清液密度为1.038 g/mL。可为钻井平台产生的废弃水基钻井泥浆的高效、无害化处理提供技术支撑。
The efficient and harmless treatment of waste water-based drilling mud generated by drilling platforms is essential to the production process. An experimental study is conducted on chemically enhanced solid-liquid separation of water-based drilling mud produced in a well drilling operation in Pengshen, Sichuan. The effects of gel breaker with single reagent, two or three reagents on solid-liquid separation of mud are systematically discussed through experimental research. The results showed that in the single factor experiment, the solid-liquid separation effect of adding quicklime alone is the best, with a dosage of 0.8 g/50 mL; in the twofactor experiment of the synergistic effect of the two reagents, the dosage of FeSO4 and CaO should be controlled at 0.6 g/50 mL; in the orthogonal experiment of the three reagents, the order of causality that affects the separation effect is FeSO4>CaO>PAC chloride. It is concluded that under the optimal conditions, the ratio of PAC, FeSO4 and CaO is 0.3∶0.4∶0.15, and the density of the clear liquid obtained is 1.038 g/mL. The study can provide technical support for the efficient and harmless treatment of water water-based drilling mud produced by the drilling platform.
