Problems solved by technology

Wet process mainly includes absorption method and wet oxidation method, etc. At present, the desulfurization process used in the petroleum industry generally has problems such as complex process, large floor area, difficult operation, large equipment investment and high operating cost, which obviously cannot meet the requirements. Practical requirements for oil and gas field production
[0003] At present, the most used method is to inject a desulfurizer into the pipeline. The desulfurizer is an alkaline solution of hydrogen sulfide in the reducing liquid phase. It is continuously injected into the pipeline according to a certain amount through the chemical pump to neutralize the hydrogen sulfide and generate The effect of neutral salt, but the price of desulfurization agent is relatively high, and it is not easy to store. For the agent accidentally leaked during operation, in addition to certain damage to the human body, it will also cause pollution to the soil
And if the ratio is not proper, the corrosion rate of the pipeline will be accelerated

Abstract

The invention discloses an automatic oil / gas well hydrogen sulfide treatment device which comprises a static mixer, an oxidant inlet, a reduction pipeline, a pH sensor, a reducing agent inlet, a metering pump and a control cabinet, wherein an oxidant is fed into the static mixer from the oxidant inlet and is mixed with an oil / gas well product in the static mixer; fluid obtained after mixing flows into the reduction pipeline from the static mixer; the reducing agent fed from the reducing agent inlet is pumped into the reduction pipeline from the metering pump; the pH sensor is used for transmitting a detected pH value of the fluid in the reduction pipeline to the control cabinet; the control cabinet is used for controlling the rotation speed of the metering pump according to the pH value of the fluid, and used for adjusting the addition amount of the reducing agent. The automatic oil / gas well hydrogen sulfide treatment device has the characteristics of being small in investment, small in size, convenient to mount, low in operation cost, good in automatic control and the like, and the long-term problem that operators can be hurt by leakage as a pipeline is corroded by hydrogen sulfide in the oil exploitation industry can be solved.

Description

technical field [0001] The invention relates to the technical field of oilfield exploitation, in particular to an automatic hydrogen sulfide treatment device for oil and gas wells used for oil and gas well output. Background technique [0002] Hydrogen sulfide is highly toxic, highly corrosive and odorous, and is also the main sulfur-containing component in oil and gas. With the increase of energy demand, the exploration and development of high hydrogen sulfide oil and gas fields in my country has been continuously intensified. Hydrogen sulfide in the output of oil and gas wells not only causes corrosion of pipelines and equipment, but also seriously threatens personal safety. There are many processes for removing hydrogen sulfide in the process of oil and gas field development. However, simple, economical and effective hydrogen sulfide removal technology and equipment are still difficult problems that need to be continuously explored and studied. Oilfield production has t...
