电吸附方法在油气勘探中的试验研究

阐述电吸附方法在油气勘探中的应用原理 ,指出任何油气藏周围都存在一个强弱不均的天然电场、氧化还原场及地球化学场 ,而与油气藏伴生的金属元素在这些物理化学场的共同作用下会发生溶解并向地表迁移 ,于地表形成后生地球化学异常。异常空间形态呈顶部晕或环带晕特征。通过在已知油田上方野外采集与常规化探相同的土壤次生晕样品 ,在室内的特殊装置内通电后 ,籍吸附介质捕集能够电运移的元素离子 ,经测试分析获得指示油气藏上方向的明显异常。又在未知区的电吸附异常区内经钻井验证获得高产工业油井 ,证实电吸附方法对寻找油气藏具有一定的有效性。

AN EXPERIMENT STUSY ON APPLICATION OF ELECTRIC ADSORPTION METHOD TO OIL AND GAS EXPLORATION

The article introduces application theory of electric adsorption method in oil and gas exploration and points out that there is a natural electric field,oxidation-reduction field and geochemical field uneven in intensity,surrounding oil and gas pool.Metallic elements associated with oil and gas pool will be solved and transported up to the surface,forming supergene geochemical anomalies under the co-processes of these physical-chemical fields.The anomaly shape in space shows characters of top halo or ring halo.Soil samples simialar to that of routine geocemical exploration were taken above the known oil field and put in special device in lab.The electronically transported ions were trapped using absorption medias after turning on the power.Clear anomaly that indicates oil and gas pool below was received through determination.A highly productive industrial oil well has been found by boring test on an unknown electronic absorption anomaly area.It is therefore proved that electric absorption method is effective in oil and gas exploration.
