●浮阀稳定器（FWL型）：浮阀稳定器多用于井底型稳定器中，在防止井斜的同时当发生井喷、井涌时，浮阀阀盖
自动将水眼关闭防止井喷事故的发生。浮阀稳定器具有强度高，过流面积大耐高温高压，既有稳定器作用，又能控
制井底液流，起防堵阀作用。
Float valve stabilizer is mainly used in near bit type stabilizer while working for preventing from borehole
deflection, when blowout or well kick takes place, the float valve stabilizer will automatically shut off inside
bore of tool to ***oid the accident. The tool owns features such as high strength, large flowing area, high
temperature resistant and high pressure resistant, etc. Not only as a stabilizer but also can play anti-clongging valve
role in controlling downhole liquid flowing .
