Abstract
本发明涉及的是一种潜油直线电机式气井同井注采装置及其注采工艺，其中潜油直线电机式气井同井注采装置包括潜油直线电机、油管、上柱塞、气液分离器、下柱塞泵，油管位于套管内，油管下端连接潜油直线电机，潜油直线电机下端连接气液分离器，上柱塞设置于油管中，上柱塞之上为水柱，上柱塞下端连接活塞杆，活塞杆下端穿过气液分离器连接下柱塞泵的下柱塞一，下柱塞泵入口位于气液分离器中，封隔器连接在下柱塞泵外筒二下端，用于隔离注入层和采出层。本发明利用潜油直线电机作为注入泵的动力源，利用与上部油管中一定高度的水柱在上柱塞上产生方向向下的压力作为辅助动力源；通过上冲程和下冲程的交替进行，实现气液混合物的有效分离和注入。
