[0033] 1. Screening of microorganism indoor strains

[0034] pass +5-18 For well crude oil analysis, use emulsification dispersion test and growth test test to compound suitable oil production microbial strains from a series of strains.

[0035] After compounding with different strains and media, etc., the strains suitable for the crude oil of the well are determined according to the growth of microorganisms and the effect of emulsifying and dispersing crude oil.

[0036] After screening experiments, the final determination GV6 for +5-18 Well huff and puff strains.

Abstract

A method is about microorganism throughput producing oil. First, microorganism indoor bacterial is filtrated after well is washed by heat water and is about 5 days in normal state. The ahead fluid of Xm3 nutrient fluid should be injected before microorganism bacterium liquid is injected. Microorganism bacterium liquid about X ton is injected into stratum, and the process of injecting bacterium is from high concentration to low concentration. Xm3microorganism nutrient fluid is injected for preparing postposition liquid after pouring bacterium is finished. Well is closed 5days. Well is closed 5days. The effect of the invention is: the method of microorganism throughput producing oil insures the microorganism bacterium breeding at certain number in deep well to achieving the goal of filling strata hole, solving jam by the metabolite generated by full fusion of base oil, clearing away wax and increasing oil, improving oil production.

Description

technical field [0001] The invention belongs to an oil recovery method, in particular to a microbial huff and puff oil recovery method. Background technique [0002] Microorganisms are low-level organisms with various types, tiny bodies and simple structures. Microorganisms generally refer to small organisms with a body size of less than 0.1 mm. The tiny characteristics of individuals enable microorganisms to obtain five characteristics that higher organisms cannot possess, namely, small size and large area, fast absorption and transformation, vigorous growth and reproduction, strong adaptability to frequency variation, and distribution Wide variety. [0003] Research on microbial oil recovery methods began in the 1920s. In 1926, Beckmann proposed the application of microbial activities to enhance oil recovery. Since 1954, mine field tests have been successively carried out in the former Soviet Union, Poland and other countries and regions, and certain test results have be...
