FIELD: oil and gas production. ^ SUBSTANCE: measuring probe for oil and gas well and/or casing consists of main case and measuring device. As the measuring device there is used at least one robot arm attached to the main case and at its free end equipped with a rotary contact tip of a polygonal shape facilitating successive contact between surface of the tip and internal wall of the oil and gas well and/or casing without slip. Also, the tip is equipped with at least one sensor recording response of geological formation to a signal, emission of which directly to geological formation is performed via contact points. ^ EFFECT: more accurate and fast measurements in well and casing. ^ 19 cl, 1 dwg |
