Abstract

The invention provides a device and process for detecting the content of toxic gas in oil field formation water, and the process is realized by utilizing the device for detecting the content of toxic gas in oil field formation water, and comprises the following steps: the oil field formation water enters a temperature control device according to actual formation pressure and formation temperature; oil field formation water flow enters a hydrogen sulfide sensitive element, a mercury sensitive element and a radon gas sensitive element in the process of passing through the temperature control device, and hydrogen sulfide, mercury and radon gas in the oil field formation water are detected in the hydrogen sulfide sensitive element, the mercury sensitive element and the radon gas sensitive element. And detection is completed when the content values of hydrogen sulfide, mercury and radon gas displayed on the display screen are stable. The device and the process can quickly, accurately and quantitatively determine the content of toxic and harmful gases such as radon gas, mercury and hydrogen sulfide dissolved in the oil field formation water, and related operators can formulate preventive measures in advance according to the determined toxic and harmful gas content result, so that oil and gas safety exploration, development and production and the life health of the related operators are ensured.

Description

technical field [0001] The invention relates to a device and a process for detecting the content of toxic gas in oilfield formation water, and belongs to the technical field of oil and gas exploration and safe production. Background technique [0002] With the expansion of oil and gas exploration to deep and unconventional fields, more and more oil and gas resources have been discovered, developed and utilized, which has greatly eased the tense situation of China's natural gas supply. However, these deep formation waters contain more or less toxic and harmful components, and some of them seriously exceed the standard, posing a threat to safe production and life and health. Among them, hydrogen sulfide has attracted attention due to its abnormal smell, and many natural gas with high hydrogen sulfide content have been desulfurized. But radon and mercury have not attracted much attention. The existence of radon gas will not only cause corrosion of equipment, reduce pipeline o...
