Underground three-phase self-adaptive separation device

The invention relates to an underground three-phase self-adaptive separation device. The underground three-phase self-adaptive separation device is characterized by comprising a three-phase separation unit and a plurality of two-phase separation units mounted on the three-phase separation unit. The underground three-phase self-adaptive separation device is scientific and reasonable in design, can ensure thorough separation of three phases, prevents gas from entering an oil well pump, improves the pump efficiency of the oil well pump, meanwhile, can be suitable for continuous and intermittent separation, can satisfy the demands of different yields and oil-gas ratios, and is wide in application range. 本发明涉及一种井下三相自适应分离装置，其特征在于：包括三相分离单元及若干安装于三相分离单元上的两相分离单元。本发明设计科学合理，可以确保三相的彻底分离，防止气体进入抽油泵，提高抽油泵的泵效；同时能够适用于连续及间歇分离，且能够满足不同产量及油气比的需要，适用范围广泛。
