Siphon type petroleum single well metering device for oilfield exploitation

Abstract

The invention provides a siphon type oil single well metering device for oilfield exploitation, and relates to the technical field of metering devices. An upper tank body is fixedly mounted at the top of the left end of the supporting table; a lower tank body is fixedly mounted at the top of the right end of the supporting table; the bottom of the rear end of the supporting table is fixedly in butt joint with a weighing table. An upper siphon is vertically mounted at the right end of the inner cavity of the upper tank body; a lower siphon is vertically mounted at the left end of the inner cavity of the lower tank body; the upper end of the upper siphon is in butt joint with a buffer tank; and the lower end of the buffer tank is fixedly butted with a metering cylinder. The platform scale is arranged in the weighing table and can be used for weighing the weight of discharged petroleum, so that the weight of the discharged petroleum is conveniently compared with the measured volume, on one hand, whether metering is accurate or not can be determined through mutual comparison, on the other hand, whether the petroleum density is consistent with the conventional petroleum density or not can be reversely deduced, and therefore the oil quality is determined, and the problem that measurement is prone to being inaccurate is solved.

Description

technical field [0001] The invention relates to the technical field of metering devices, in particular to a siphon-type oil single-well metering device for oilfield exploitation. Background technique [0002] Single-well metering is the most critical basic work in the construction of standardized and digital oilfields. It is an important link in the simulation and dynamic analysis of oilfield production and operation of reservoir data values. The production plan has important guiding significance. [0003] In the process of single well measurement, because the oil is easily solidified due to temperature changes, the flow process is extremely unstable, and the time is fast and slow, resulting in inaccurate measurement. At the same time, even if the measurement is inaccurate Problems are often difficult to detect in time, and there is a lack of comparative data. SUMMARY OF THE INVENTION [0004] In view of this, the present invention provides a siphon-type oil single-well ...
