发明名称 SYSTEM FOR MEASURING DRILLING MECHANICAL LOADS (VARIANTS)
摘要 <p>The invention relates to a system for measuring mechanical loads applied on a drill pipe during drilling comprising a measuring part provided with a body thereof formed by a part of the drill pipe, an internal pipe which has a specified length and is fixed, by the first end thereof; inside the body, wherein a sealed chamber is formed between the body inner surface and the outer surface of the internal tube, at least one first measuring projection is embodied inside said sealed chamber on the body inner surface, at least one second measuring projection is embodied on the outer surface of the internal pipe projection, the number of the second measuring projections corresponds to the number of the first measuring projections and a measurable spacing gap is formed between the first and second measuring projections. The inventive system also comprises a sensor for measuring the spacing gap between the first and second measuring projections and a remote computer device for calculating loads applied on the drill pipe during drilling on a basis of data about the size of the measurable spacing gap received from said sensor.</p>
