阿拉新气田东部汤池构造油气微生物评价应用研究

Research of Allah Fields of Oil and Gas Microbiological Evaluation in Tangchi Eastern

油气微生物勘探法(MPOG)是地表勘探法的一个分支,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。在阿拉新气田东部汤池构造区,以微生物异常为基础,对微生物异常区域进行了分析研究,初步评价了该井区内的油气资源潜力。结果表明:工区内微生物异常分布非均匀,但有五处相对较大的微生物异常区,且连片性较好,表明油气潜力较大;异常区由南向北呈由弱变强的趋势;且工区内基本为油异常,气异常几乎为背景值状态,结合区域地质资料给出了勘探建议。并部署了了五口评价建议井。

Microbiological prospecting technology for oil and gas （MPOG） is a branch of surface reservoir evalu ation, it mainly studies the correlation relationship between the microbiological anomaly in the subsurface soil layer and the reservoirs in deep underground. It can be based on anomaly detection of microorganism, can be evaluated and forecast oil and gas underlying the existence and nature of possession. Microbiological anomaly area was ana lyzed based on the microbiological anomaly in Allah Tangchi tectonic zone east of gas fields. The results showed that heterogeneity of microbiological anomaly exists with five relatively large areas, which lace is well. Which oil and gas potential of the larger. The direction tendency of microbiological anomaly from south to north revealed a weak to strong trend. Combining with geological background, favourable gas bearing area has been predicted andfive ap praisal Well is proposed.
