Two key points in high resolution seismic prospecting for coal are (1) to design reasonable acquisition parameters for exploration tar- get,and (2) to preserve useful high frequency components as many as possible during data processing.In the coal seismic exploration in CH basin,we used the following reasonable acquisition parameters. lms sampling interval,235m maximum offset,10m group interval and 16-250 Hz frequency band.In seismic data processing,high-pass filte- ring,band-pass filtering and time-variant filtering are respectively used according to different normal reflection times(to times);the length of deconvolution operator ranges from 60 or 70 samples;white noise accounts for 10-15%;and particularly,refined velocity analysis,true amplitude recovery and migration technique are applied to data pro- cessing.Coal seam can be approximately located using instantaneous information,interval velocity,reflection coefficient and bright spot. Furthermore,the minor fault whose throw is only half phase,uncon- formity and palaeochannel can be clearly shown on the high resolution seismic section.

在煤田高分辨率地震勘探中,首要的问题是针对研究的对象设计合理的采集参数,在资料处理过程中要尽量保持已采集到的高频有效信息。在CH盆地的煤田地震勘探中,采样间隔选为1ms,最大炮检距为235m,道距为10m,接收频宽为16—250Hz。在资料处理中,针对不同的t_0时间,分别实施高通、带通和时变滤波;反褶积因子长为60、70个样,白噪因子为10~15%;注重精细速度分析、真振幅恢复和偏移技术的应用。利用瞬时信息、层速度、反射系数和亮点显示,能够近似地识别出煤层的空间位置。此外,利用高分辨率地震剖面还可识别出错动半个相位的断层,并清楚地显示地层不整合接触关系和古河道的形态。

This paper discusses problems about the realization of software and the disposition of hardware of the self—tuning control over the temperature in the furnace and the experi- ments.Specifically,the problems include the following aspects:data collection,identifica- tion,emulation and a series of specific problems in software development of self—tuning, real-time control. Through the tho kinds of practical experiments of self-tuning control and PID con- trol,the experiment results show that the stable performance of controlling temperature by self-tuning control is better than that by PID control.Furthermore,the self-tuning con- trol is easy to realise on a microcomputer and doesn't often need manually adjusting parameters.Thus,the self-tuning control has great value of wide applications.

Exploration and development in Dongxin area have been done for more than 20 years, The subsurface geological structure and fault system in this area were not ascertained in many years because of the complicated subsurface geological structure and troublesome surface conditions, so that drilling exploration often failed. Consequently, threedimensional seismic exploration was conducted in this area. First,field acquisition parameters were correctly determined by comprehensively analysing known geological materials, geophysical, data and other conditions in this area. Then some surface obstacles were effectively avoided by taking 17 different field layouts, thus ensuring complete subsurface three-dimensional data point network and uniform multiplicity. Five new hydrocarbon-bearing blocks and 18 new seismic highs in old hydrocarbon-bearing blocks have been discovered by interpreting these three-dimensional seismic data. 102 wells of 107 completed wells have industrial oil flows, success rate being above 95%.

东辛地区已勘探开发20多年,但由于地表和地下地质情况复杂,该区的地质构造形态和断裂系统始终没查清楚,经常造成钻探失误。为此,在该区进行了三维地震勘探工作。首先,根据已知地质及物探资料,结合该区具体情况,严格选择了地震资料野外采集参数。然后在施工中采用了17种野外观测系统,有效地避开了地表某些障碍物的影响,从而保证了地下三维观测点网的完整性和覆盖次数的均匀性。利用这块三维地震资料,发现新含油区块5个,在原含油区块中发现新高点18个。在已完钻的107口井中有102口井见到工业性油流,钻探成功率在95%以上。
