一种新型气锚已经设计出来，并对其进行了现场测试。由于这种气锚采用了将叠板弹簧置于气锚套筒和套管内壁之间，而将气锚套筒靠在套管内壁上的偏心结构，气锚进口开在液体浓度较高的套管内壁处，因而效率有所提高。对气体干扰影响泵效的油井，这种偏心气锚可能会显著提高产量。 A new type of gas anchor has been designed and field tested. Because this air anchor adopts the laminated spring to be placed between the gas anchor sleeve and the inner wall of the sleeve, and the gas anchor sleeve abuts against the eccentric structure on the inner wall of the sleeve, the gas anchor inlet is opened at a higher liquid concentration The inner wall of the casing, so the efficiency has improved. Gas disturbances affect the pump efficiency of the well, which can significantly increase the yield of gas anchors.
