从电测资料看河南XD矿井突水原因

通过对该区区域水文地质特征，地质构造特征的综合分析，结合地面电测对区内构造，岩溶裂隙发育规律的解释结果认为：ＸＤ矿井恰好处在一强含水带区域内，煤层的开采势必破坏地层间原有的水力均衡状态，在其薄弱地带形成突水。     

三维直流电阻率的非线性反演成像

研制了直流电经数据解释的全三维反演成像方法。由于反演算子是严重不适定的，所以我们采用正则化算法来解释这些反演问题，为了得到高分辨率成像和一种精确而的反演方法，利用非线性正则化反问题的准凸面特性，并选取最佳正则化参数，反演算法能单独解释地面数据，单孔数据，跨孔数据，或者这些数据的任意组合，得到了综合数据组的高分辨率的成像。

介绍了针对地球物理勘探所面对的世界性难题－“矿与非矿的有效区分”开展的研究和取得的突破性进展，以及广西泗顶铅锌矿外围的应用成果。     

小创造

在电法勘探中,电活员的工作不但要求准,而且要求快,以前电活员工作时,在通话时接通司机,当测量时要立刻并联上测量电极而且要求接触良好,这样工作时电话员的工作很紧张,湖北电法队在开展技术革命中‘就地取材’的创造了小小接线盘,携带既轻便,用起来也方便。 线路图如下:     

苏联近年来在电法勘探方面的工作

目前,地质调查工作中的电学方法具有极其重大的意义,几乎在各种地质勘探工作中找不出不采用电法的工作,只是使用的程度不同而已.虽然电法勘探在苏联发展的时期较短,这种方法在1924年才首次得到运用,但是,无论在理论方面和实际运用方面,它已迅速地发展起来了.     

大功率激电和瞬变电磁法在青海锡铁山深部找矿中的应用

为了在锡铁山铅锌矿的外围深部找矿勘查中提供深部地球物理信息，首次将大功率激电和大功率瞬变电磁法应用于接地条件十分恶劣、地形复杂的锡铁山地区。采用原长春地质学院研制的大功率设备，对供电电极和常规供电方式进行了改进，使供电电流达到10A以上，保证了大功率激电得以在该地区的实施。并于第28勘探线向南延伸部位发现一低阻高极化激电异常和瞬变电磁异常，由于这两种方法的异常可相互验证，再结合矿山外围地质研究工作．推断该异常为深部铅锌矿体所引起。这一新发现为矿山外围找矿提供了深部地球物理依据。

on-Seismic Surveying on Steep High Structural Zones： An Example of Hetianhe Gas Field

Mashan is a typical area, complex on the surface,steep of the formations and complicated with the structures. It is very difficult to carry out seismic surveying. The preliminary result of the seismic prospecting indicated that only monoclines exist in the area. Drilling discovered Hetianhe gas field. After integrating non-seismic (gravity, magnetic and electromagnetic) prospecting, it was revealed that there exist two rows of structural highs, which were proved by the later seismic surveying. The paper analyzed all the data in the area and recognized that the integrated prospecting to be carried out in a complicated area is effective and necessary.     

Comprehensive Information Interpretation in Oil and Gas Exploration—An Example of Buried-Hill Oil and Gas Field in the Jizhong area

The petroleum geophysical and geological comprehensive interpretation with whole-information of gravitational, magnetic, electrical and seismic methods has played an important role in the exploration and development of the buried-hill oil and gas pools in the Jizhong area, including the oil pools in the weathering surface of the buried-hill with “oil generated in the Cenozoic and accumulated in thePaleozoic”, and the gas pools in the buried-hill with “oil generated in both the Cenozoic and the Paleozoic, accumulated in the Paleozoic and sealed by the Mesozoic”. In recent years,high-precision gravitational and magnetic surveying and continuous electromagnetic profile (CEMP) prospecting were carried out on the Yangcun Slope that had been preliminarily recognized as a monocline in the Paleozoic structural-stratigraphy. After the geophysical and geological comprehensive interpretation with whole-information of gravitational,magnetic, electric and seismic data, the gas-bearing buriedhill zone of Matou-Huanghuadian was discovered.     

The Role of Gravity, Magnetic and Electric Prospecting Techniques in the Geological Survey of the Qiangtang Basin

The Qiangtang basin is one of the large-scale basins in China, which is located in the high-altitude and cold area. In 1994 the preliminary gravity, magnetic and electric prospecting work was undertaken in this area. Over three years the gravity, magnetic and electric reconnaissance work had been completed. The integrated interpretation of complex gravity, magnetic and electric data had identified the boundary of the basin. The relationship between the basin and mountains is a south-north ramp structure. The basin structure consisted of one uplift and two sags, five depressions and two arches. The complex evaluation showed that the regions of Baitanhu and Youyiquan in the Qiangtang basin were considered to be the most perspective ones in sense of oil-gas bearing.
