The Study of Embedded Multifunctional Downhole Test System

It is necessary to test the logging instrument during its development and production. Generally, these test tasks need to be completed in the experimental well, which will not only bring a lot of inconvenience for researchers and site workers, but also waste a lot of manpower and material resources. The embedded multifunctional down hole test system can replace experimental well to complete simulation logging, which facilitates the development, test and adjustment of the logging instrument. First, this paper introduces the main control circuit design of the test system. Secondly, it proposes the design plan of the main modules. Finally, the paper proposes the design flow and main data structure of the software development. Developed with SDI framework and component technique based on MFC, the test system has the function of command sending, data acquisition, displaying and so on. Oil field test shows that this system has good performance in acoustic signal acquisition and processing, and has the characteristic of plug and play, real-time control and so on.
