''Terek-3'' a well flowmeter for hot water

Journal Article:

Abstract

For studying ther applicability of an injection well with injection of hot water (with temperature to 150-200/sup 0/C) it is necessary to have well flowmeters which have high sensitivity and performance capacity at this temperature. In developing the well remote flowmeter ''Terek-3'' the All-Union Scientific research and Planning-Design Institute for comprehensive automation of oil and gas industry made a decision to use a drive-less packer developed by the authors of the article for the well flowmeter ''Terek-1'' designed to study high-output wells. Because of the use of the drive-less packer, the sensitivity of the flowmeter was considerably improved and the lower limit of measurements were decreased to 60 m/sup 3//day. In order to reduce friction in the supports of the turbines, agate step bearings and cores were used made of steel 40KKhNM. The upper step bearing was installed in the instrument housing, and the lower in the body of the turbines. This reduces the possibility of its contamination in the measurement process. One should also bear in mind that with an increase in temperature, the viscosity of water diminshes (roughly 5-fold with temperature of 150/sup 0/C). Therefore, with a decrease in the influence of viscosity on the readings of the  More>>

Therefore, with a decrease in the influence of viscosity on the readings of the flowmeter in the instrument, a turbine was used suggested by V. I. Bar-Sliva. In this turbine the blades are separated from the step which guarantees not only the obtaining of the maximum moving momentum but also reduces the influence of the change in viscosity on the operation of the turbine. The impulse output signal obtained with rotation of the turbine with magnet is transmitted on a single-strand cable to a surface apparatus consisting of a condensator frequency meter and universal logging recorder N-381 which guarantees recording of the changed consumption on a diagram tape as a function of depth or time. Experimental samples of the well flowmeter ''Terek-3'' passed state inspection tests.}
