Successfully control low-efficiency wells to explore new ways

News from Sinopec News Network on June 23, news came from Gudong Oil Production Management District 4 that the Shengli Oilfield Petroleum Engineering Technology Research Institute's microbial well GO8-20XN109 heavy oil well in this area has implemented microbial single-well huff and puff tests, and the oil has increased by 10 Multiple times, water cut decreased by 18.

Microbial single-well huff and puff technology is to inject nutrients into the reservoir to activate the endogenous microorganisms in the reservoir, allow them to grow and metabolize in the reservoir, and then act on the near-well zone, restore its permeability, improve the fluidity of crude oil, and ultimately improve Technology of recovery factor

In response to this situation, the Institute of Microbiology has actively combined with the technical personnel of the Geology Institute and the Technology Institute of the oil production plant to construct an internal and external composite throughput process that does not move the microbial throughput of the pipe string according to the physical properties of the block reservoir, the nature of the crude oil and the structure of the microbial flora of the oil reservoir.

Laboratory research results show that under the conditions of the test block reservoir, the oil seepage resistance is reduced by 67%, realizing the effective production of crude oil under low-energy conditions
