发明名称 OIL OR GAS WELL PRODUCTION MONITORING DEVICE
摘要 FIELD: oil-and-gas industry. ^ SUBSTANCE: oil or gas well production monitoring device comprises self-contained geophysical instruments mounted below production pump with the help[ of anchors in intervals of analysed beds. Right above top anchor a guide funnel is fixed with its upper part accommodating stem on lugs and its lower part housing contact sleeve to cable terminal to be connected thereto. Top and bottom cylinders are fixed above and below extraction pump with their funnels directed upward and downward, respectively. Note here that one of the funnel walls is arranged vertically at the distance of 3 to 5 mm from the cylinder outer wall. Tube is arranged between top and bottom cylinders in funnels holes to accommodate geophysical cable with contact rod to move therein. Note also that bells are arranged above guide funnel and top cylinder cowl, each with diametre smaller than that of cowl by two diametres of geophysical cable, plus 10 to 15 mm. ^ EFFECT: higher accuracy of data. ^ 3 dwg
