APPLICATION OF OIL PRODUCING TECHNOLOGY OF HUFF AND PUFF INJECTION OF MICROBE IN INDIVIDUAL WELL IN HUABEL OIL FIELD

This paper briefly introduce the development history and increase productivi-ty mechanism of microbe oil recovery technology, as well as the application of this technolo-gy in Huabei oil field. By analyzing the effect of this technology applied in 3O comparab1e testing wells, the applicable range and effective features of the oil producing technology of huff and puff injection of microbe in individual well as well as several problems deserved to be paid attention to when choosing well are summed up. This paper also points out that the indoor bacterial species screenlng technology ls the key of success of microbe oll recovery, that the reasonable determination of microbe injection amount and perlod are the important factors affecting economic benefit. This paper finally points out that the technology of huff and puff injection of microbe in individual well is a good stimulation method for the "potato"reservoirs of small fault block and with poor communication and low formation temperature.
