A kind of gas of often association during hair.
In oilfield exploitation procedure, hydrogen sulfide problem occur, there are mainly two types of situations：One is oil reservoir sulfide hydrogen itself,
Oil reservoir contains always hydrogen sulfide due to Flurial deposit reasons, the crude oil of institute's output；One is the secondary hydrogen sulfide during oil reservoir development
Problem, i.e. oil reservoir itself not sulfide hydrogen, but due to water filling, thermal recovery etc., change the property on crude oil or stratum, make originally not
Hydrogen sulfide containing crude oil becomes sour crude oil.Hydrogen sulfide all has high harmfulness to people and equipment, at the same can to downhole tubular goods and
Collection transmission pipe network causes heavy corrosion, directly affects oilfield safety production.
The safety exploration of sulfide hydrogen oil gas field and security development are gradually taken seriously, to ensure equipment and personnel safety, carrying
High crude quality needs to reduce hydrogen sulfide content, or even removing hydrogen sulfide in exploitation of oil-gas field, the defeated, processing procedure of collection.Cause
This, the exploitation of the improvement of hydrogen sulfide gas Treatment process and new technology in oilfield exploitation procedure is high sulfur-bearing oilfield life always
In production one of the problem of urgent need to resolve.
Currently used sulfur method has：Physical desulfurization, chemical desulfurization, biological desulphurization, wherein chemical method are the most frequently used
Method, the chemical substance that can be reacted with hydrogen sulfide, including alkali, peroxide, formaldehyde, nitrite and a plurality of types of
Amine, these substances can convert hydrogen sulfide to other sulphur compounds.In actual use, it needs to be asked according to hydrogen sulfide to be solved
The property of topic, medium, process characteristic select hydrogen sulfide removal scheme
Invention content
The purpose of the present invention is to provide a kind of hydrogen sulfide scavengers, can be sent out with hydrogen sulfide oily, in gas and water by effective
Biochemical reaction achievees the purpose that remove hydrogen sulfide, it is ensured that oil gas field is kept the safety in production.
The object of the present invention is achieved like this：A kind of hydrogen sulfide scavengers, including host agent, adjuvant, synergist and water；Its
Mass percentage is：Host agent is 10-30wt%, adjuvant 10-15wt%,；Synergist is 1-5wt%, remaining is water；Host agent
It is s-triazine, adjuvant system polyethylene polyamine substance, synergist system metal ion chelation agent.
Present invention is mainly used in oilfield exploitation procedure, hydrogen sulfide in Produced Liquid, natural gas, associated gas, casing gas
Removal.The specifically used method of the present invention：For production system, the present invention can be directly added into oil, Wellbore of Gas Wells；For collecting defeated system
System, the present invention can be directly added into gathering line, injection pipe network by medicine system；For natural gas, associated gas and other Containing Sulfurs
Hydrogen, the present invention can also be matched with desulfurizer, air-washer, achieve the purpose that remove hydrogen sulfide.The present invention passes through
Absorption, reaction, remove the hydrogen sulfide in oil gas field production process Crude Oil, sewage, associated gas, casing gas, it is ensured that personal safety,
Prevent the generation of hydrogen sulfide poisoning event, reduce harm of the hydrogen sulfide to production equipment, reduces pollution of the hydrogen sulfide to environment.
The hydrogen sulfide scavengers host agent that the present invention selects is triazine substance, is nitrogen-containing basic substance, can be with hydrogen sulfide phase
Interaction converts hydrogen sulfide to innocuous substance；To improve hydrogen sulfide scavengers liquid phase sulfur limitation effect, increase in the present invention more
Ethylene polyamine substance increases metal ion chelation agent as synergist as adjuvant；Adjuvant, synergist selection, proportioning can
To require to adjust according to specific hydrogen sulfide removal, in the hope of obtaining best hydrogen sulfide removal effect.In conclusion energy of the present invention
It is chemically reacted with hydrogen sulfide oily, in gas and water by effective, achievees the purpose that remove hydrogen sulfide, it is ensured that oil gas field safety
Production.
