The invention discloses a logging winch electric control system with a power capstan, which comprises a main winch electric control system, a power capstan electric control system and a capstan electric control system which are connected through a cable, and the cable extends to a derrick through a ground pulley and finally reaches an oil well; the main winch electric control system achieves ultra-deep well logging operation through cooperative control with the power capstan electric control system and the capstan electric control system. The invention further discloses a method for controlling the logging winch by using the electronic control system. According to the electric control system, the electric control system of the logging winch with the power capstan is used for reducing the cable tension on the roller, and the cooperative control problem of the main winch and the power capstan in logging of reservoirs exceeding ten thousand meters is solved.
本发明公开了带动力绞盘的测井绞车电控系统,包括主绞车电控系统、动力绞盘电控系统和绞盘电控系统,三者之间通过电缆来衔接,电缆通过地滑轮延伸至井架,最后到达油井;主绞车电控系统通过与动力绞盘电控系统、绞盘电控系统协同控制来实现超深井测井作业。本发明还公开了使用上述电控系统控制测井绞车的方法。本发明电控系统利用带动力绞盘的测井绞车电控系统降低了滚筒上的电缆拉力,解决了超万米储层测井中主绞车与动力绞盘的协同控制问题。
