Abstract

Disclosed is a simple measurement device for oil field well-head liquid levels. The measurement device mainly solves the problems that no device in the prior art can be used for conducting simple measurement of oil field well-head liquid levels. The measurement device comprises quick connectors at the left end and at the right end of an oil field bypass valve, hoses at two ends, rotating connectors at two ends, ball containing tee joints at two ends, direct current inductance approach switches at two ends, a non-metallic circular pipe, metal balls and a passing speed meter, wherein stopping wires are arranged inside ball containing tee joints; quick connectors at two ends respectively correspond to and are sequentially connected with hoses, rotating connectors at two ends and ball containing tee joints at the left end and the right end; the non-metallic circular pipe is connected between ball containing tee joints at the left end and the right end; metal balls are arranged inside ball containing tee joints at the left end and the right end; signal output ends of direct current inductance approach switches at two ends are connected with corresponding input ends of the passing speed meter; and the connection mode of ball containing tee joints in a pipeline is a rotating structure, i.e., ball containing tee joints at the left end and the right end are in a T-shaped structure which can be rotated to be inverted. The measurement device is simple in structure, convenient to carry and capable of achieving quick and simple measurement of oil field liquid production volume.

Description

technical field

[0001] The invention relates to a device applied in the field of oil well fluid production measurement. Background technique

[0002] At present, the oil well production measurement methods commonly used in oilfields mainly include: glass tube oil measuring orifice plate gas measurement, tipping bucket oil measuring orifice plate gas measurement, two-phase separation measurement method and three-phase separation measurement method, working condition data analysis method, etc. Glass tube oil measurement is a traditional method commonly used in domestic oil fields, accounting for more than 90% of the total number of oil wells. The advantage of this method is that the equipment is simple and the investment is low. However, due to the conversion of production by intermittent oil measurement, the error of the crude oil system is relatively large, about 10% to 20%. The tipping bucket is mainly composed of oil gauge, counter and so on. When one bucket is full, tu...
