A knowledge of petroleum evolution is of critical significance in oil prospecting.First of all, the upper and lower limits of petroleum evolution are of prime importance in the evaluation of an oil-gas bearing area, because the nature and scale of oil-gas are controlled by the type and maturity of kerogen in sedimentary rocks For example, Tertiary oil-bearing basin's in eastern China (including the offshore continental shelf) is in the stage of oil-gas formation and an upper limit of petroleum...

A knowledge of petroleum evolution is of critical significance in oil prospecting.First of all, the upper and lower limits of petroleum evolution are of prime importance in the evaluation of an oil-gas bearing area, because the nature and scale of oil-gas are controlled by the type and maturity of kerogen in sedimentary rocks For example, Tertiary oil-bearing basin's in eastern China (including the offshore continental shelf) is in the stage of oil-gas formation and an upper limit of petroleum evolution can be recognized. The major control of oil-gas nature for this region is the great abundance of terrestrial organic materials and its lower muturity. The marine carbonate strata in eastern China are older in age, and in the stage of oil-gas muturity with a lower limit of evolution. On the basis of the evolution model preliminarily established with respect to a certain region, the lower limit of oil and gas in carbonate district is lower than that of mudstone oil-bearing basins reported from other places in the world, with its petroleum lower limit corresponding to the stage of coke-lean coal or that of pynobitumen. For a correct evaluation, prospecting map in terms of petroleum evolution should be prepared in accordance with the model suitable for that region together with various organic geochemical index.A veiwpoint of petroleum formation, evolution and extinction will provide a deeper insight into the origin of oil and gas.The stages of petroleum evolution must likewise be taken into account if geochemical indexes for oil-generating rocks are to be applied correctly. For instance, OEP and clay minerals of mixed layers can only be taken as oil-generating index in the case of low muturity stage. Application of organic indexes of bitumen A/Corganie is difficult to recognize oil-generating rocks because of the ranity of bitumen A at the starting and ending stages during petroleum evolution. The bulk of organic materials in carbonate rocks are highly possible to be lost during diagenesis. From the consideration of petroleum evolution, during which stage it is lost may exert an influence on the evaluation of carbonate oil-generating rocks. Therefore, the study of sedimentary facies and diagenetic facies is also necessary.

Aeromagnetic survey in People's Eepublic of China has gone a long way since twenty-six years ago. Up to the end of 1978, we had flown about seven million line-kilometers, and the area actually covered amounted to about 7.5 million square kilo-meters (including offshore surveys 1.2 million square kilometers in area). Now, the total number of aircrafts used for aeromagnetic surveys has reached nearly 30 per-year, and correspondingly there have been organized the brigades of aerogeophysical research.Aeromagnetics has played an important role in the search of industrial minerals. Local aeromagnetic anomalies were found in about 20000 localities, of which, 3.5% were later verified as magnetite deposites or other useful metallic ore-bodies. By use of indications given by the aeromagnetic anomalies, more than 240 iron and other metallic deposits have been discovered, of which, 41% are of large or moderate scales. Aeromagnetic surveys also had great successes in the search of oil/gas structures. Almost all of the oil/gas bearing sedimentary basins were covered by aeromagnetic surveys, the area covered amounting to nearly 4.8 million square kilometers (including 1.2 million square kilometers off-shore). In exploration of such well-known oil-fields as Daching, Shengli, Dagang etc., aeromagnetic surveys have played an important role. The effectiveness of aeromagnetic surveys for the study of geotectonics and deep crustal structure was verified, not only on theoretical basis but also in practical applications. By use of aeromagnetic mapping, large deep faults were located. They are important tectonic features and possible indicators of mineralization.Finally, the prospect, of the development of aeromagnetic surveys in China is dis-cussed.

我国的航空磁测工作,已经有二十六年的历史。到1978年底为止,全国已完成了近700万测线公里,实际覆盖面积约750万平方公里(其中包括海域120万平方公里)。现在全国各个部门中,用于航空磁测的飞机,每年可达30来架,建立了相当的航空物探队伍。 航空磁测在矿产普查中发挥了重大作用。圈定的局部航磁异常达20000多处,其中反映和被证实为各种规模的磁铁矿床及其它金属矿床的异常,占总数的3.5%。以航磁异常为线索,新发现的铁矿和其它金属矿达240多处,其中大中型的占41%。 航空磁测在石油构造普查中,也取得了巨大的成绩,几乎是各个含油气盆地都曾被普查过,覆盖的面积达480万平方公里(包括海域120万平方公里),为发现大庆、胜利、大港等著名油田,起了重要的作用。构造磁测在大地构造和深部构造研究方面,不仅从理论上而且从实践上都具有相当的地位,这已为地质界所公认。航空磁测确定的深大断裂带,是非常重要的地质构造单元,也是各种有用矿产普查的重要线索。 最后,作者还提出了对我国航空磁测研究发展工作的意见。

This paper gives us a brief introduction to the complex channel analysis which aims at obtaining the dynamic parameters with the characteristics of surface seismology, such as transient amplitude, transient phase, transient frequency and apparent reflected polarity. It is of great significence either in interpreting the oil-gas reserves and obtaining the lithologic information.

本文概述了复数道分析的目的在于求取表征地震波动力学特征的一些参数——瞬时振幅、瞬时相位、瞬时频率和视反射极性。这对解释油气藏和获取岩性信息有重要意义。 要获得较好的参数剖面,必须正确选择和改进某些计算公式,正确使用合理的处理方法。本文通过对合成记录的处理说明,对瞬时振幅做积分滤波处理可得到光滑可靠的瞬时振幅剖面,并可大大消除由随机干扰造成的假视极性。用反正弦公式代替常用的反正切公式求取瞬时相位,可获得与地震波周期一致的相位剖面,克服了相位畸变。利用经过积分滤波的瞬时振幅对瞬时频率做加权处理,可使瞬时频率更加稳定。 本文借用有限元素表示的射线轨迹法,在6912计算机上对一种常见的构造地质模型作了合成记录,用它计算了瞬时振幅、相位、频率和视极性剖面;分析了这些剖面的特征以及利用这些特征进行地震解释的可能性。 本文还对形成复数道的基本算法——离散希尔伯特变换的各种改进算法进行了比较,计算结果表明,在频率域中做希尔伯特变换较为有利。
