摘要:
 油气井酸化施工后，井内返排液体中夹带的酸性刺激性气体，经静态喷淋净化后，均未达到排放标准，整体净化效率低，严重污染环境，威胁人身安全。为提高喷淋净化装置对酸性气体的净化效率，研究了一种以叶轮为主要部件的动态喷淋净化装置。通过理论计算气液接触面积，验证了动态喷淋装置净化气体的高效性。采用流体力学计算方法，对动态喷淋的叶轮结构进行了优化设计，优选出叶片数为6个、倾斜角为40°的叶轮，获得16 r/min转速的动态喷淋净化装置。大港油田X井采用该装置处理后的酸性气体净化效率由4906%提高到9588%，较静态喷淋提高了9543%，满足油气田作业现场对酸性气体的净化要求，实现了作业现场小型、喷淋效果高效的目的，具有广泛的实用性。
Abstract:
 The acidic irritant gas contained in the liquid flowing back from the oil&gas well after the acidizing operation usually fails to meet the emission standards after being treated by static spraying purification. The low overall purification efficiency leads to serious environmental pollution and personal safety threats. To improve the efficiency of the purification system, a dynamic spraying purification device with impeller as the main component was designed. By theoretical calculating the gasliquid contact area, the high gas purification efficiency of the dynamic spraying device was verified. With the hydrodynamic calculation method, the impeller structure was optimized. The impeller with 6 blades and 40° inclination angle was selected to form the dynamic spraying purification device with the optimal rotation speed of 16 r/min. Since this device has been used in well X of Dagang Oilfield, the purification efficiency of acid gas is increased from 4906% to 9588%, 9543% higher than that of the static spraying purification treatment, meeting the requirements for acid gas purification and achieving the goal of small footprint and high purification efficiency at wellsites, which has a wide range of practicability.
