Crude oil water content measuring device and method based on radio frequency method

Abstract

The invention relates to a crude oil water content measuring device and method based on a radio frequency method. A left connecting pipe is arranged at the left end of an inner pipe, and a right connecting pipe is arranged at the right end of the inner pipe; an antenna protective sleeve with one end stretching into the right connecting pipe is arranged on the wall of the right connecting pipe, a radio frequency antenna is arranged in the antenna protective sleeve, a plug is arranged at one end, located in the inner pipe, of the antenna protective sleeve, a seal ring is arranged between the antenna protective sleeve and the wall of the right connecting pipe, an outer sleeve pipe is arranged outside the inner pipe, and a displayer and a radio frequency measuring device connected with the displayer through a wire are arranged on the outer sleeve pipe; the crude oil water content measuring device comprises a radio frequency signal generator, a signal amplification unit, a radio frequency power detection unit, a measuring resistor, a signal conditioning unit and a controller. The crude oil water content measuring device is reasonable in design, simple in structure, high in measuring accuracy, wide in range and suitable for all large oil fields.

Description

technical field [0001] The invention belongs to the technical field of measuring devices or equipment, and in particular relates to a measuring device for the water content of crude oil based on a radio frequency method. Background technique [0002] In the process of crude oil production, in order to reasonably and efficiently estimate the production capacity of oil wells, evaluate the working status of oil wells, and allocate the cost of manpower and material resources reasonably, many measurement parameters have been formulated as evaluation standards. Among them, the water cut of crude oil is an important reservoir data of oil wells, and it is also the main production parameter. Whether the measurement of water cut data is accurate directly affects whether the production status of each production layer can be grasped and understood in a timely and accurate manner, so as to use this as a basis to guide production, take effective measures or improve the process to rational...
