Description
Technical field：
The present invention relates to hydrogen sulfide in a kind of oil well production process to eliminate suppressing method, is stored up particular for since water filling changes
Sulfate reducing bacteria increases the place of the hydrogen sulfide gas and associated erosion object that generate caused by layer and flow string initial condition
Reason method.
Background technology：
The hydrogen sulfide gas generated in oilfield process is serious to the normal Influence of production in oil field, by taking large oilfield as an example,
Due to the output of hydrogen sulfide, hydrogen sulfide safety in production claimed range is greatly exceeded, causes more mouthfuls of oil wells to be forced to stop production, or even envelope
Well causes great economic loss, while also causing great personnel safety hidden danger in process of production.Being directed at present should
Class well, major measure are that the mode of period lye well-flushing is taken to maintain to produce, i.e., periodically right according to hydrogen sulfide safety in production needs
Production hydrogen sulfide oil well takes lye well-flushing, and the mode for removing hydrogen sulfide maintains to produce, and has the spies such as duty cycle is short, operation is dangerous
Point cannot fully meet the needs of oil field production, especially for some faster wells of the hydrogen sulfide speed of response, without good
Administering method.It is badly in need of carrying out relevant technology research, solves influence of the hydrogen sulfide to production.
Mainly there is following two the mechanism of generation hydrogen sulfide in oilfield exploitation procedure：One is since stratum is rich in vulcanization
Hydrogen or associated minerals composition cause to form hydrogen sulfide and ferrous sulfide scale, another kind during oil gas extraction to be due to water filling
Sulfate reducing bacteria grows the corrosion product generated in journey.At present both at home and abroad for produce hydrogen sulfide gas well processing mode mainly with
After output based on desulfurization, but this method can not implement oil well production；Liu Guangcheng (oil gas field environmental protection, 2014,24,20)
Et al. report and add competitive bacteriostatic agent in well, add the absorption patterns such as activated carbon to Bohai Sea oil field in crude oil storage tank
Hydrogen sulfide improvement plays the role of preferable, and Yan Zhong et al. (oil and gas chemical industry, 2010,06,21) is reported in water filling
The mode that fungicide is added in system controls the generation of hydrogen sulfide；Present invention is particularly directed to by sulfate reducing bacteria grow institute
The hydrogen sulfide of generation eliminates the side of sulfate reducing bacteria and its related saprophytic bacteria by well, oil well synthesis using efficient germicide
Method is inherently eliminated the source of hydrogen sulfide generation, compares existing administering method, while strengthening water well treatment measure,
To oil well by the way of strengthening improvement, removal of hydrogen sulfide source of generation has and administers what more thorough, the quick, term of validity was grown
Feature.
Invention content：
The purpose of the present invention overcomes the shortcomings of the prior art, and provides a kind of elimination inhibition oil well life of energy highly effective and safe
The generation of hydrogen sulfide in production especially inhibits bacteria breed and the hydrogen sulfide that generates, the oil well production process with good result
Middle hydrogen sulfide eliminates suppressing method.
The purpose of the present invention can be achieved by the following technical measures：
This method includes to the treatment measures of tubular column of water well and water filling near wellbore zone and to oil well pipe and its near wellbore zone
Treatment measures are carried out at the same time；
The treatment measures to tubular column of water well and water filling near wellbore zone include the following steps：
(1) biostatic agent that mass concentration is 1%~10% is filled to stratum near wellbore zone 2m；
(2) biostatic agent that mass concentration is 1%~5% is filled into Full water well cylinder；
(3) well is closed, is reacted 24~48 hours；
(4) into Full water well cylinder, the period fills biostatic agent；When injecting water delaunay triangle to oil well, if oil well produces
Go out concentration of hydrogen sulfide and is not reduced to 20mg/m3When, then increase biostatic agent filling periodicity, adds the period according to effective response for water flood
Time calculates, and formula is：
NAdd the period=TFlood-response time/ the period
(5) wait for that oil well hydrogen sulfide content is reduced to 20mg/m3Afterwards, the addition concentration of biostatic agent is adjusted to 10~
30mg/L；
It is described that oil well pipe and its near wellbore zone treatment measures are included the following steps：
(a) biostatic agent that mass concentration is 1%~10% is squeezed to oil-well strata near wellbore zone 4m；
(b) biostatic agent that mass concentration is 1%~5% is filled into the full pit shaft of oil well；
(c) oil well is closed, reaction is gone into operation after 24~48 hours；
(d) into oil well full pit shaft, the period fills biostatic agent；When injecting water delaunay triangle to oil well, if oil well produces
Go out concentration of hydrogen sulfide and is not reduced to 20mg/m3When, then increase biostatic agent filling periodicity, adds the period according to effective response for water flood
Time calculates, and formula is：
NAdd the period=TFlood-response time/ the period
(e) wait for that oil well hydrogen sulfide content is reduced to 20mg/m3Afterwards, the addition concentration of biostatic agent is adjusted to 10~
30mg/L；
