Abstract

The invention discloses a data downloading device which comprises a downloading handle and a centralizer assembly. The downloading handle comprises a handle body, a downloading connector and a downloading cable, the handle body comprises a body head end, a body tail end and a body middle part, the downloading connector is installed at the body tail end and can rotate, the downloading cable is connected with the downloading connector at the body tail end and used for transmitting data, an O-shaped ring is arranged on the handle body and used for centralizing and locking the downloading handle, the centralizer assembly comprises a centralizer, a communication connector and an annular groove, the downloading connector is connected with the communication connector, and the O-shaped ring is embedded into the annular groove. The downloading handle can rotate, so that the downloading handle is not limited in direction during plugging or pulling and is convenient and quick to use and convenient to plug and pull. The O-shaped ring in the device is embedded into the annular groove, and the downloading handle can be effectively prevented from dropping from an instrument.

Description

technical field [0001] The invention relates to the field of downhole data downloading, in particular to a data downloading device. Background technique [0002] my country is a large country with very rich oil and gas reserves, and has a large number of oil and gas fields and oil and gas production enterprises. During the exploration and development of oil and gas fields, logging is required after drilling to understand the oil and gas content of the formation. [0003] The acquisition of traditional geologging data is to use cables to put instruments into the wells for measurement. However, in some cases, such as highly deviated wells or horizontal wells with wells whose inclination exceeds 65 degrees, it is difficult to use cables. Put the instrument down. In addition, the well wall is not in good condition and is prone to collapse or blockage. It is also difficult to obtain well logging data at this time. Since the drilling fluid is circulated during the drilling proce...
