摘要

为了提高稠油油藏开发效益,与新疆油田合作,优选了混源采油菌组合,采用单井吞吐的生产方式,分2批对21口稠油开发井进行了微生物开采矿场试验。结果表明,所选用的采油菌组合对胶质、沥青质含量高的稠油作用效果显著,经采油菌作用,作业区的稠油粘度大幅度降低,在停止注蒸汽的情况下,大多数试验井都能达到经济产能,试验得到了较高的投资回报率。认为稠油微生物开采技术值得在新疆油田的稠油开发中加以推广。

Abstract

To improve the recovery ratio of oil and the production benefits of heavy oil reservoirs, Southwest Petroleum Institute and Xinjiang Oil Field cooperated to carry out the mineral field experiments of microbial enhanced oil recovery (MEOR) for heavy oil. In the experiments working bacteria or petroleum bacteria from different places were chose, and the mode of production was individual well injecting-extracting. There were 21 product wells of heavy oil in the two times. Through the influence of working bacteria, the viscosities of heavy oil were decreased greatly. With little or no hot vapor, most test wells had reached for economic productivity. High products  investments ratio had been got in the experiments. According to the results of the experiments, the working bacteria selected can obviously degrade heavy oil rich gum and asphaltene. And the mineral field experiments have many advantages, such as little investment, fast returning, greatly profits and so on. Practices have proved that MEOR of heavy oil is worth applying and generalizing in Xinjiang Oil Field.
