由于稠油段油层原油的粘度高 ,重烃组分所占比例大 ,因此造成采出井采出困难。为了寻求一种有效的微生物菌种对此类油层进行处理 ,在喇嘛甸油田东部过渡带地区稠油段油层 4口井进行吞吐试验 ,并研究了该菌种在油层中的生长、繁殖、降粘、增油等状况 ,同时对其试验效果进行了评价 Due to the high viscosity of crude oil in heavy oil reservoirs and the large proportion of heavy hydrocarbon components, it is difficult to mine production wells. In order to find an effective microbial strain to treat such reservoirs, we conducted the stimulation test on four wells in the heavy oil reservoir in the eastern transitional zone of Lamadian Oilfield and studied the growth, propagation and decline of the strain in the reservoir Sticky, increased oil and other conditions, while its test results were evaluated
