Abstract

The invention provides a 15000-meter extremely-deep well logging winch system. The 15000-meter extremely-deep well logging winch system comprises a supporting device arranged on the ground and located above an oil well, a top sheave arranged at the top of the supporting device, a wellhead device, a ground sheave, a main winch and a power winch used for bearing loads of a logging cable and a downhole instrument. The main winch comprises a first rack, a roller, a first transmission device and a first brake mechanism; the power winch comprises a second rack, a driving wheel, a second transmission device and a second brake mechanism; the driving wheel is provided with a rope groove used for winding a logging cable. By means of the 15000-meter extremely-deep well logging winch system, the tension of the logging cable can be reduced when the logging cable is wound around the winch roller, then the force generated on the winch roller is reduced, and the overall size is not changed or even reduced on the premise that the capacity of the winch roller meets the requirement; therefore, the capacity and the strength of the roller can meet the requirement for the strength of the wound 15000-meter logging cable, and the requirement for 15000-meter logging operation is further met.

本发明提供一种15000米极深井测井绞车系统，包括设置在地面上且位于油井上方的支撑装置、设置在支撑装置顶部的天滑轮、井口装置、地滑轮、主绞车和用来承受测井电缆和井下仪器的载荷的动力绞车；主绞车包括第一机架、滚筒、第一传动装置和第一刹车机构；动力绞车包括第二机架、驱动轮、第二传动装置和第二刹车机构；驱动轮上设置有用于缠绕测井电缆的绳槽。通过本发明的15000米极深井测井绞车系统，能够减小测井电缆在缠绕至绞车滚筒上时的测井电缆张力，进而减小对绞车滚筒产生的力，使绞车滚筒容量在满足要求的前提下整体体积不变甚至减小，从而能够使得滚筒的容量和强度满足缠绕15000米的测井电缆强度的需求，进而满足15000米的测井作业需求。
