1. Introduction Down-hole self-contained combined tool GEO-6 makes registration of 6 parameters: pressure P, temperature T, gamma-ray GR, fluid flow-meter Q, collar locator CCL, thermoindication STI. Using the tool allows you to:  To produce a research of injection wells in operation at a pressure at the wellhead without stopping of the injection and the formation water spout.  Research the wellbore, including the upper fresh water aquifers.  Receive the log well data from PC directly at the well.  Reduce the duration of the well research significantly due to the exclusion of works to pressure relief and upload of recovery injection mode. Information is received from the sensors to the memory block of down-hole tool where stored for measuring time. Power is supplied by a lithium battery or accumulator. After working the tool information is read into the PC. Then you can explore the results and control data on the screen as a standard log data in the time format. After combining of tool GEO-6 data with depth data it can be formed a single file of depth format (LAS). If necessary, all the data is issued to the printer in the standard form.
