The invention relates to a high-paraffin high-temperature high-
salinity oil well microorganism paraffin removing and inhibiting agent and a preparation method thereof, and belongs to the technical field of
tertiary oil
recovery of an
oil field. The
microorganism paraffin removing and inhibiting agent is prepared from the following components in percentage by weight: 5 to 10 percent of
halobacterium salinarium, 5 to 10 percent of hyperthermophilic archaeon, 8 to 15 percent of paraffin-thirsty
bacteria, 20 to 25 percent of industrial brine, 5 to 10 percent of
starch, 0.5 to 3 percent of peptone,0.5 to 3 percent of
yeast extract and the balance of water. The preparation method of the
microorganism paraffin removing and inhibiting agent comprises the following steps: adding the industrial brine, the
starch, the peptone and the water into a
fermentation tank, regulating pH (Potential of
Hydrogen) value of a solution, rising the temperature to 40 to 55 DEG C, uniformly stirring, then heating to 125 DEG C, and sterilizing for 25 minutes; adding the
yeast extract, the
halobacterium salinarium, the hyperthermophilic archaeon and the paraffin-thirsty
bacteria after cooling to 40 to 60 DEG C, fermenting for 48 hours by keeping the temperature be 55 to 60 DEG C, and cooling to
room temperature, thus obtaining the microorganism paraffin removing and inhibiting agent. According to microorganism paraffin removing and inhibiting agent and the preparation method thereof, disclosed by the invention, the problems of low high-temperature high-
salinity tolerance and poor paraffin removing andinhibiting effect of microorganism paraffin removing and inhibiting strains at present can be effectively solved.
