Single-well water-containing-rate remote metering device and transmission method of single-well water-containing-rate data

Abstract

The invention provides a single-well water-containing-rate remote metering device and a transmission method of single-well water-containing-rate data. The single-well water-containing-rate remote metering device can achieve single-well on-site on-line continuous metering and is small in metering error, low in manufacturing cost, high in metering speed and capable of saving labor and material resources. The device comprises a water-containing analysis instrument composed of a probe, a radio frequency signal generator, a center processor, a data storage and an RS 485 communication port. The center processor is connected with a remote transmission module. According to the transmission method of the single-well water-containing-rate data, the single-well water-containing-rate remote metering device is arranged in each well, the center processor stores a water-containing-rate curve mathematical model in advance, the water-containing-rate in a wellhead production fluid is measured and transmitted to a data center server through the remote transmission module, meanwhile, the measured data are uploaded to a central control room through the RS485 communication port, the measured water-containing-rate data are collected in real time, remote zero calibration and parameter configuration are carried out, then the data are transmitted to a host of a user through the Internet, and a manager can learn about and monitor single-well water-containing metering operations remotely.

Description

technical field [0001] The invention relates to a single well water content remote metering device and a water content data transmission method. Background technique [0002] The automatic metering technology of water content in the produced fluid of single well in oilfield is a complex metering technology, which has been blank since the oilfield was exploited. Today, when digital oilfields are established, the problem of automatic monitoring and measurement of water content in single well produced fluid has become more and more prominent. Mainly manifested in: [0003] a. At present, the traditional manual method is still used to measure water cut in single well production. This method takes a long time for sampling and testing, is labor-intensive, and consumes a lot of manpower and material resources. [0004] b. The traditional manual method does not detect the geological changes in the well in time, so the guidance of oil production lags behind. [0005] c. The manua...
