发明名称 METHOD OF EVALUATION OF STATIC AND DYNAMIC LEVELS OF FLUID IN ANNULAR SPACE OF WELL EQUIPPED WITH ELECTRIC CENTRIFUGAL PUMP
摘要 FIELD: oil and gas production. ^ SUBSTANCE: invention refers to oil industry and can be implemented at survey of wells. The method of evaluation of static and dynamic levels of fluid in annular space of a well equipped with an electric centrifugal pump includes evaluating of levels by geo-physic methods. Prior to evaluation of levels a hole is made in a face plate. A perforated plastic pipe narrowed in its lower part and secured on external surface of a flow string is lowered together with the flow string and the pump into the well. Bottom of the plastic pipe is arranged 0.5-1.0 m above the pump; an upper end of the plastic pipe comes out to surface through the hole in the face plate. A gap between the plastic pipe and the hole of the face plate is leak proofed; a measuring tape with a level sensor is lowered inside the plastic pipe. Surface of fluid is contacted; a level is measured and the measuring tape is withdrawn out of the plastic pipe. ^ EFFECT: simplification of measuring procedure of fluid level.
