Title:
METHOD FOR INHIBITING BIOGENIC HYDROGEN SULFIDE IN OIL FIELD
Document Type and Number:
WIPO Patent Application WO/2023/246505
Kind Code:
A1
Abstract:
The present invention relates to a method for inhibiting biogenic hydrogen sulfide in an oil field. A synergistic inhibition system combination agent containing Bacillus licheniformis GW1 is added into an oil field system, wherein the Bacillus licheniformis GW1 has been deposited in the China General Microbiological Culture Collection Center on October 20, 2021, and has the deposit number of CGMCC No. 23631. Compared with the prior art, in the present invention, when Bacillus licheniformis GW1 and an activator nitrate are added, the inhibition rate of hydrogen sulfide can reach not less than 90.81%; on this basis, the inhibition effect is enhanced after the synergistic inhibitor is added, and the inhibition rate of hydrogen sulfide can reach 99.37% at most; and a system constructed by the inhibition bacterium, the activator and the synergistic inhibitor of the present invention can effectively reduce the content of hydrogen sulfide in the oil field system and has the advantages of a good inhibitory effect, low economic costs, and a simple injection system, etc.
