油井液面测量可以了解油井的供液能力,确定机采泵的沉没度,制定合理的油井工作制度。由于安全环保需要,在井口以下100-200米深度处安装有封隔器,因此采用现有地面测试仪器无法对机采井液面进行监测。需要开展固定式过封隔器液面监测技术的研究。目前,国内外油气井的液面监测主要是声波测试,测试时将仪器与井口连接器,并和井下套管连通,利用无弹头子弹引爆所产生的声波在沿油套环形空间向井底传播时,遇到回音标、节箍、油
Oil well level measurement can understand the liquid supply capacity of the well, determine the degree of submergence of the pump and formulate a reasonable oil well working system. Because of the need of safety and environmental protection, the packer is installed at the depth of 100-200 meters below the well head, so the existing ground test instrument can not monitor the level of the machine-made well. Need to carry out fixed over packer level monitoring technology research. At present, the liquid level monitoring of oil and gas wells at home and abroad is mainly sound wave testing. When testing, the instrument is connected with the wellhead connector and connected with the downhole casing. The sound wave generated by the detonation of the bullet without projectile propagates downhole along the annular space of the oil sleeve Encountered echo standard, Festival hoop, oil
