According to the large-depth double-roller logging winch, a bearing cable is wound around a cable roller assembly, a cable connector of the bearing cable is sequentially wound around a cable arrangement device and a guide pulley assembly to be connected with a sensor assembly, a cable roller rotates to change the wire outlet amount of the bearing cable, and then the sensor assembly is lifted or lowered. The cable arranging device is arranged in front of the cable roller assembly and used for guiding the bearing cable to be stably and orderly wound and released on the cable roller assembly. The guide pulley assembly is arranged above the cable roller assembly and used for guiding the bearing cable. The sensor assembly is used to perform well wall measurements. The two bearing cables are connected to the two ends of the fixing frame, stable lifting of the sensor in a large depth range is guaranteed by synchronously controlling take-up and take-out of the two bearing cables, the structure of a winch is greatly simplified, and the space of the winch is saved. And the torsion releaser is arranged to release the torsion, so that the stability of the sensor is ensured.
本发明公开了一种大深度双滚筒测井绞车,承重电缆盘绕于电缆滚筒组件上,承重电缆的电缆接头依次绕排缆器和导向滑轮组件与传感器组件连接,电缆滚筒转动自身以改变承重电缆的出线量,进而提升或下降传感器组件。排缆器设置于电缆滚筒组件的前方,用于引导承重电缆平稳有序地在电缆滚筒组件盘绕和释放。导向滑轮组件设置于电缆滚筒组件的上方,用于引导承重电缆。传感器组件用于执行井壁测量。使用两根承重电缆连接到固定架的两端,通过同步控制两根承重电缆的收线和出线保证了传感器在大深度范围内的平稳升降,极大简化了绞车结构,节省了绞车空间。设置扭力释放器,将扭力进行释放,保证传感器的平稳。
