FIELD: oil and gas industry. ^ SUBSTANCE: device for consumption control of fluid circulating through the well that contains estuarine detachable pipe branch with adapter and drain pipe includes fluid consumption control means. Note that fluid consumption control means is made in a form of flow-metre, installed at well output and connected between adapter of estuarine detachable pipe branch and drain pipe of the well. The length of flow-metre is L0, it is equipped with input area of LIN length and output area of LOUT length that together with flow-metre form measuring assembly. Note that LIN length is selected not less than 3.2 of L0, LOUT length is selected not less than 2L0, and measuring assembly is located at an angle (2070) to horizontal axis of drain pipe. ^ EFFECT: improvement of fluid consumption control accuracy. ^ 3 cl, 1 dwg |
