Title: Method for reducing viscosity loss by means of regulating and controlling microbial community structure composition in polymer prepared from water produced by oilfield
Inventor: WEI LI
IPC: C09K8/582
Filed: 2021-05-24
Abstract: A method for reducing viscosity loss by means of regulating and controlling microbial community structure composition in a polymer prepared from water produced by an oilfield. An ecological viscosity loss stabilizer mother liquor is prepared by means of using (by mass fraction) 15-25% of a nitrate, 1-5% of a nitrite, 1-2% of a stabilizer, 0.1-0.5% of nutrient elements, and the balance of tap water or water produced by an oilfield for polymer preparation. By means of adding a nitrate and a nitrite, the ecological niche of denitrifying bacteria can be improved, the ecological niche of sulfate-reducing bacteria is reduced, and the community composition of microorganisms in an injection allocation system is changed, so that the number of sulfate-reducing bacteria in the injection allocation system is decreased, the viscosity loss of a polymer is reduced, and the effective viscosity of the polymer is ensured. Furthermore, the sulfate-reducing bacteria in the injection allocation system can be effectively inhibited, and no harm is caused to beneficial bacteria in an oilfield system.

Abstract: A blockchain-based sub-account transaction processing method and system, a computer device and a storage medium. A terminal receives a private key of a user and transfer information which comprises a sub-account address, the sub-account address comprising a primary account address; signs the transfer information by means of the private key to obtain a transfer information ciphertext; and sends to a blockchain node a transfer request which comprises the transfer information ciphertext and a public key. The blockchain node acquires the corresponding sub-account address and the primary account address according to the transfer request; and determines, according to the sub-account address and the primary account address, whether the sub-account is a sub-account of the user. According to the method, multiple accounts of the user are structured to a primary account and multiple sub-accounts, the sub-account address comprising the primary account address. The multiple accounts use the same private key to avoid the situation where multiple private keys are mixed up or forgotten. By determining, according to the sub-account address and the primary account address, whether a sub-account is an account owned by the user, an account theft can be detected in time, and user loss is avoided.
