摘要： 建场测深是一种采用大功率人工场源激发,具较高分辨率和勘探精度的电法勘探新技术。建场测深剖面对陆东地区石炭系内幕结构反映较为清晰,其电性结构揭示上石炭统发育上、下2 套火山岩序列,中间为沉积岩层间隔,并能够反映火山岩序列内部岩性的横向变化及火山构造的发育情况。不同地区石炭系残留程度不同,相应的地层电性结构存在明显差异。在北疆石炭系勘探领域,建场测深技术具有较好的应用效果,为地震勘探起到重要补充作用。

Abstract: Electric field sounding is a new technique for electric prospecting by means of high power and artificial field source shot with high resolution and accuracy. Its profile can be applied to clear reflection of the Carboniferous structures in LuDONG area in Junggar basin. There exist two sets of volcanic sequences in upper and lower parts of the Upper Carboniferous, sedimentary stratum in the middle. The lateral variation of lithology within the volcanic sequences and the development of their volcanic structures are also reflected in it. The study shows that in different areas the Carboniferous is in different degrees of remains which cause that obvious differences occur in corresponding electric structure of volcanic rocks. It is suggested that the electric field sounding technique as an important supplement process is of good applicable results for the Carboniferous explorative domain in North Xinjiang.

Key words: Junggar basin, LuDONG area, field sounding, Carboniferous, volcanic rock
