微生物勘探技术在呼和地区生物气勘探中的应用

Application of Microbial Technology for Oil and Gas Exploration in Hohhot Area

采用油气微生物勘探技术(MPOG),对呼和地区进行了油气微生物勘探研究。通过对工区油气微生物勘探的研究,完成了工区内油和气的微生物异常区的圈定,结果显示微生物异常与工区内已完钻井的含气情况基本符合;同时结合区内的油气藏压力、地表条件、样品特性等各种因素进行了讨论;分析表明,MPOG比较适合在该盆地内运用。最后再以微生物异常为主要前提,结合区内现有的资料(如钻井、测井和录井等资料),对呼和地区的油气远景进行了评价,并给出了如下结论:呼和地区的油气远景较差,异常显示较好的区域位于工区中心,建议加强对该地区所取得的各种资料进行详细综合研究,特别是和3井与和4井之间所在的异常区进行重点研究。

Microbial prospecting technology for oil and gas(MPOG) exploration was studied in Hohhot Area.By studying the MPOG technique,the area of microbial anomalies of oil and gas was completed.The result showed that the microbial anomalies and the gas-bearing conditions in the operation area were consistent,and discussion was carried out in combination with reservoir pressure,surface conditions,sample characteristics,etc.The analysis indicated that the microbial prospecting technology was more suitable for the basin exploration.Based on the main premise of microbial abnormalities,and in combination with drilling and logging data and well log,the oil and gas-bearing prospects of Hohhot Area are evaluated The results show that in Hohhot Area the exploration prospects of oil and gas are poor,and the region with better anomaly display is located in the center of the operation area.It is proposed that a comprehensive study should be carried out on various data and information of the area in a detailed and comprehensive way,especially the study of the anomalous region between the Well 3 and 4.
