摘要
针对油田产出液中普遍存在的高含气和小粒径气泡难以有效分离的问题,提出了一种基于惯性预分离和旋流分离原理的新型气液分离器结构。通过采用Plackett-Burman试验设计方法,确定了影响分离效率的关键结构参数,建立了结构参数与气液分离效率之间的数学关系模型,并基于PB试验优化结果,进一步分析了入口角度对气液惯性-旋流分离器分离性能的影响。研究结果表明,结构参数的显著性由高到低的顺序为:溢流管伸入长度>锥角>柱体长度>柱体直径>溢流管直径>底流管直径。在入口角度为100°时,惯性预分离效果最佳,气液分离效率达到97.02%。
Aiming at the difficulty in separating the high gas content and small particle size bubbles in the produced fluid of oil field,a new gas-liquid separator structure based on inertial pre-separation and cyclone separation principle was proposed and Plackett-Burman(PB)experimental design method was used to determine the key structural parameters affecting the separation efficiency,including establishing the mathematical relationship model between the structural parameters and the gas-liquid separation efficiency.In addition,based on the PB test results,the influence of the inlet angle on the separation performance of the gas-liquid inertial-cyclone separator was analyzed.The results show that,the order of significance of structural parameters from high to low is the overflow pipe extension length>cone Angle>cylinder length>cylinder diameter>overflow pipe diameter>underflow pipe diameter.When the inlet Angle is 100°,the inertial pre-separation effect becomes the best and the gas-liquid separation efficiency can reach 97.02%.
