Description
Technical Field
The invention relates to the technical field of underground operation, in particular to an electric control oil bag flow collecting type flow water content tester.
Background
The production profile logging data is an important basis for the formulation and adjustment of an oilfield development scheme, and the water content measurement is one of important parameters of the production profile logging. At present, the method widely applied to the measurement of the water content of the oil-water two-phase flow of the vertical oil well in the oilfield production is mainly an impedance type water content meter. The impedance type water content meter works originally to determine the water content by measuring the ratio of the conductivity of the oil-water mixed phase in the well to the conductivity of the water phase in the well. When the collecting umbrella is opened, the liquid inlet is opened, and the conductivity of the oil-water mixed phase is measured, which is called a mixed phase value; when the collecting umbrella is folded, the liquid inlet is sealed, and the instrument is used for measuring the conductivity of the water phase in a sampling state, which is called the total water value. The ratio of the full water value to the mixed phase value is the relative response of the water content, the size of the relative response of the water content reflects the size of the water content of the fluid to be measured, and the accurate measurement of the full water value is a key factor of the water content measurement. The umbrella is required to be continuously supported and folded in the well logging process, so that the unstable risk of the instrument is increased; if the liquid inlet can not be completely closed when the umbrella is closed, the oil phase fluid enters the sampling tube, so that the full water value can not be measured normally, the water content measurement is failed, and accurate liquid production profile logging data can not be obtained.
In addition, when the existing water content meter adopts a turbine flowmeter to measure fluid flow, low-flow measurement cannot be performed due to the requirement of starting displacement, in order to increase the fluid flow speed, a flow collecting umbrella is generally adopted to collect oil-water mixed phase liquid into a central flow hole, and a water content sensor and a turbine flow sensor are arranged in the central flow hole, so that measurement work can be completed. Because of the existence of the collecting umbrella, the test can only be stopped point by point in the underground logging process, and the test is very difficult for the oil layer with a very close adjacent distance.
