Description
Technical field
The invention belongs to oil-gas field hydrogen sulfide and administer technical field, particularly relate to the method that a kind of oil field is administered agent and administered hydrogen sulfide with hydrogen sulfide.
Background technology
The existence of oil field hydrogen sulfide is to operating personnel's health, life security, and the safe operation of petroleum installations all has great hazardness; The existence of hydrogen sulfide also can cause the obstruction of stratum and pipeline, increases the desulphurization cost of downstream processing factory, influences the quality of processed oil.Therefore, solving the hydrogen sulfide problem is the top priority that oilfield safety is produced, and is the important behave that guarantees the oilfield safety High-efficient Production.
The origin cause of formation of hydrogen sulfide can be divided into two big classes: a class is a biogenesis, mainly is to be produced by sulphate reducing bacteria (SRB) metabolism sulphate reducing; Another kind of is abiotic origin, produces by vitriol thermochemistry reductive action or by magmation.
At present, still there is not a kind of method of administering different origins hydrogen sulfide simultaneously.The general method of administering biogenesis hydrogen sulfide is to adopt sterilant, this method cost height, and can not kill sulphate reducing bacteria fully, bacterium is developed immunity to drugs.And the method for administering abiotic origin hydrogen sulfide normally adopts the chemical desulfurization agent, this method is cured the symptoms, not the disease, and can not solve the output problem of hydrogen sulfide, and part chemical desulfurization agent cost height, and the danger that causes fire or blast is arranged, and full production of oil supply neoasozin caused new hidden danger.
Summary of the invention
The present invention is for solving the method that the technical problem that exists in the known technology provides a kind of oil field to administer agent and administer hydrogen sulfide with hydrogen sulfide.
The present invention administers agent by add hydrogen sulfide in oil-field flooding or production system, can activate beneficial microorganism such as nitrate reduction bacterium (NRB) on the one hand, make it and sulphate reducing bacteria generation competition exclusion effect, thus the activity of inhibition sulphate reducing bacteria, the generation of control hydrogen sulfide; On the other hand, hydrogen sulfide is administered agent can make part have the metabolic process generation alienation of the sulphate reducing bacteria of alienation metabolic function, and nitrate/nitrite replacement sulfur hydrochlorate is as electron acceptor(EA), thereby avoids producing hydrogen sulfide; In addition, hydrogen sulfide is administered the desulfurization microorganism (DSB) that agent can also activate the oil reservoir origin, in its metabolic process the hydrogen sulfide conversion is removed.Therefore, change microbial ecological, can realize treating both principal and secondary aspect of disease oil field hydrogen sulfide problem to control the hydrogen sulfide generation or to utilize microbial metabolism to transform hydrogen sulfide.
One of purpose of the present invention provide a kind of have can administer oil field different origins hydrogen sulfide, instant effect, become the oil field of characteristics such as body, safety non-toxic, environment protection are good to administer agent with hydrogen sulfide.
It is to solve the technical scheme that the technical problem that exists in the known technology takes to be that agent is administered with hydrogen sulfide in oil field of the present invention:
