Oil and gas integrating instrument

Abstract

An oil and gas integrating instrument mainly aims to solve problems of complicated structure, poor metering precision, poor stability and the like of an oil and gas integrating instrument in the prior art. The oil and gas integrating instrument is characterized in that an MSP430F437 type chip, a 24C256 type chip, a PCF8563 type chip, a 74HCI165D type chip, an RSM485S type chip and an LTC4411 type chip are connected to form a detected data processor of the integrating instrument; a liquid level detector of the integrating instrument comprises a buoy, a central tube made of an austenitic stainless steel material, an annular hollow floater and a plurality of reed switches; a pair of cuboid neodymium iron boron magnets is symmetrically fixed onto the inner wall of the floater, and balls are embedded on outer side walls of the magnets; and the floater is sleeved on the outside of the central tube, a plastic liner tube is arranged inside the central tube, and the reed switches are distributed in the central tube at intervals. The oil and gas integrating instrument is simple in structure, elements are replaceable, and the oil and gas integrating instrument further can be connected with an upper computer to remotely transmit data, and has the advantages of high metering precision, good stability and the like.

Description

technical field [0001] The invention relates to a metering device for oil well liquid production which is used in conjunction with a separator in an oilfield metering station. Background technique [0002] 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. That is to install a glass tube liquid level meter with a length of about 80cm and a connecting pipe with the separator on the oil-gas separator in the metering station. According to the relationship between the rising height of the water in the glass tube and the oil volume in the separator, the weight of the oil in the separator can be obtained, and the time required for the liquid level in the glass tube to rise can be measured to calculate the production of the oil well. In this way, the glass tube measures oil by manual watch timing and manual conversion, which is labor-intensive and has human errors. In addition, th...

Problems solved by technology

After a period of application, it is found that this existing instrument has the following problems: since the existing magnetic inversion liquid level gauge is directly used to measure the liquid level, and the structure of the magnetic inversion liquid level gauge has not been adaptively improved, in this The performance of the measurement and storage circuit designed on the basis of this mechanical structure is not good, which leads to the complex structure of the final instrument and the low stability of the instrument, and the measurement accuracy is very poor.
