Description: The test tool for high temperature, high pressure oil and gas wells live test tube, it has overcome the previous full-bore formation testing tool shortcomings and deficiencies, with the nature of innovation in the structure and performance, not only in general under downhole conditions the test is more convenient, secure, reliable, accurate, and more adapted to high temperature, high pressure, deep, stratigraphic test wells, wellbore conditions require not only low, but also broadens the formation testing and other underground operations (such as perforating, acidizing, fracturing lure spray discharge, cementing operations, etc.) compatibility. |
