Problems solved by technology

Due to the continuous increase of the freezing depth of the wellbore, the number of freezing holes is also increasing, and the brine temperature during the measurement is basically -30°C or even lower. If all the freezers are measured one by one, it will not only take time and effort, but the working environment of the workers is extremely poor. At the same time, due to the inevitable leakage of some salt water during measurement, it will cause environmental pollution.

Abstract

The invention relates to a saline flow detection device of a freezer, which is especially applicable to the freezing-method shaft sinking construction. A vaporizer is sealed and communicated with a liquid distribution ring by a pipeline; the liquid distribution ring is sealed and communicated with the feeding pipe of each freezer via the pipeline and a valve; the drainpipe of each freezer is respectively sealed and communicated with a liquid accumulation ring via the pipeline and the valve and is respectively sealed and communicated with the detection ring via a hose and the valve; and the detection ring is sealed and communicated with the vaporizer by a flowmeter and the pipeline. According to the saline flow detection device, time and labor are saved, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to a device for detecting the brine flow of a freezer, which is particularly suitable for use in well drilling construction by freezing method. Background technique [0002] In drilling construction by freezing method, the brine flow rate of each freezer is an important technical index, and a reasonable brine flow rate is the key to ensure the freezing effect. The process remains basically uniform. Therefore, it needs to be tested every about one month or so. In the past, the detection method of brine flow was: pull out the hose of the brine circuit of the freezer, insert the brine flow meter, open the valve, read the flow of brine, pull out the flow meter, install the hose of the freezer circuit, and then measure the next freezer . Due to the continuous increase of the freezing depth of the wellbore, the number of freezing holes is also increasing, and the brine temperature during the measurement is basically -30°C or even low...
