| 摘 要： | 经近几年试验,我们提出用土壤吸附硫化氢气体作指标,勘查油气田新方法.并将它和相态烃法、自然电位法相配合,在已知油气田开展了试验,取得令人十分满意的效果.油气藏中含有大量硫化氢气体及含硫有机化合物.油气垂直微渗漏到近地表时,硫化物气体也随伴而至.运移过程中,硫化氢气体及含硫化合物在细菌及氧气作用下会发生一系列复杂的化学变化,如生成硫酸盐等,但经已知油气田试验结果表明,在油气藏上方近地表土壤中仍保留有明显的硫化氢气体异常,而且异常形态有一定的模式,有环状、半环状、片部和带状等不同形态.异常均和下伏油气藏或断裂构造相吻合,表明硫化氢气体测量法是勘查油气田的有效方法.更引人注目的是,它和相态烃、自然电位异常吻合的很好,异常均出现在油藏上方,表明综合使用这三种方法将会取得更好的找油气效果.

| Abstract: | Based on tests conducted in recent years. the anchors advance a new method forexploration of oil and gas fields with soil-adsorbed hydrogen sulfide as an index. Combiningthis method with phase state hydrocarbon method and self-potential method, the authorsobtained satisfactory results over some known oil and gas fields. In oil and gas accumulations, there are large quantities of hydrogen sulfide gases and sultur-bearing organic compounds. When oil and gas approach the surface through vertical micropercolation, sulfide gasesalso reach such place. In the process of migration, a series of complicated chemical changesof hydrogen sulfide gasas and sulfur-bearing compounds would tabe place under the action ofbacteria and oxygen, forming for example sulfate. Nevertheless, tests have proved that innear-surface soils over oil and gas accumulations there remain obvious anomalies of hydrogensulfide gases, which assume anular, semi-anaular, sheet and zonal shapes. The anomlies agreewith the underlying oil and gas accumulations or fault structures, suggesting that hydrogensulfide survey may be used in the exploration of oil and gas fields.Moreover, these anomaliesare in good accord with phase state hydrogen anomalies and self-potential anomalies, with allof these anomalies appearing over the oil and gas accumulations. All this shows that theintegrated utilization of these three methods would yield more satisfactory rosults. |
