| 摘 要： | 油气微生物勘探（MPOG）是地表油气藏评价的一个分支，主要研究近地表土壤层中微生物异常与地下深部油气藏的相关关系，它以成本低廉，简便快速，多解性小的特点，在镇泾油田得到充分的验证。在镇泾油田内，以微生物异常为基础，结合已有的区域油气地质、钻井和测井等资料，对微生物异常区域进行分析研究，重点解释说明了镇泾油田红河105—1057井区长821小层与油气异常的关系，并圈定出2个异常区，其异常连片分布，异常区的异常平均值较高，反映本工区内油藏控制面积较大。本工区天然气微生物异常整体水平较低，且基本上与油藏微生物异常区吻合，异常区零星分布，表明本工区的天然气多系原油溶解气。最后对工区油藏分级评价，并根据微生物勘探结果和地质特征等综合因素，在工区部署3口建议井。

| Abstract: | Microbiological prospecting technology for oil and gas(MPOG) is a branch of surface reservoir evaluation,it mainly studies the correlation relationship between the microbiological anomaly in the sub surface soil layer and the reservoirs in deep underground.It was successfully used in Zhenjing Oil Field for its low cost,simplicity,convenience and low ambiguity.In Zhenjing Oil Field,based on the anomaly of micro-organisms,combined with regional geological data,drilling and logging,etc,the authors carried out an analysis in abnormity of micro-organism,mainly explained the relationship between long 821small layer in Zhenjing Oil Field,Red River 105—1057 well area and the oil or gas abnormal.Two anomaly display areas of oil and gas were determined.Its abnormality was distributed in sectors.The abnormal average of the abnormal area was higher,reflecting large area of reservoir control in the working area.The overall level of abnormality of gas microbe in the working area is lower,and is basically consistent with the reservoir microbial abnormal area.The scattering of gas in the abnormal area indicated that gas in the working area was mostly oil dissolved gas.Finally,the authors gave a grading evaluation for reservoir in the working area,and according to the results of microbial prospecting and geological characteristics and other comprehensive factors,three suggesting wells were deployed in the working area. |
