Small and medium size vibroseis has been successfully used to generate quality data from shallow to middle depth in areas with unfavorable surface conditions and environment-protected regions adjoining to cities. However, it fails to generate desirable data in areas with deep targets and in serir and shingle zones. Beginning with a comparison between vibroseis and dynamite sources on their principles and advantages, this paper compared the fundamentals of vibroseis of large, medium, and small sizes. These three...

Small and medium size vibroseis has been successfully used to generate quality data from shallow to middle depth in areas with unfavorable surface conditions and environment-protected regions adjoining to cities. However, it fails to generate desirable data in areas with deep targets and in serir and shingle zones. Beginning with a comparison between vibroseis and dynamite sources on their principles and advantages, this paper compared the fundamentals of vibroseis of large, medium, and small sizes. These three different sizes of vibroseis were used in 2-D seismic data acquisition in Yanqi Basin. The results show that only large-tonnage vibroseis can yield quality seismic data in areas where targets are buried deeply, or in the serir and shingle zones.

中小型可控震源的应用,弥补了炸药震源在地表条件差及城市环保区无法施工的缺陷,在中浅层勘探中取得了较好的效果,但是,对于目的层埋藏较深的地区和反射品质较差的戈壁砾石区,则效果不是太好。从可控震源与炸药震源的原理及优势对比入手,分析和比较大、中、小可控震源的技术方法,并在新疆焉耆盆地二维采集中使用这三种震源进行试验,结果说明在目的层埋藏较深的地区和反射品质较差的戈壁砾石区,只有使用大吨位可控震源才能取得高品质的地震资料。

The structure styles of Middle Triassic Leikoupo formation, in central Sichuan basin, are roof slip contraction structure, which primarily is a ramp-flat thrust accompanied by close fault-bend fold with low highness. The structure styles are formed by conjunct action of regional compression and salt diaper that is caused by soft salt and gypsum within Leikoupo formation and underlying Jialingjiang formation. Analysis the processing results and corresponding field geometries for Lei11 reflection at three different...

The structure styles of Middle Triassic Leikoupo formation, in central Sichuan basin, are roof slip contraction structure, which primarily is a ramp-flat thrust accompanied by close fault-bend fold with low highness. The structure styles are formed by conjunct action of regional compression and salt diaper that is caused by soft salt and gypsum within Leikoupo formation and underlying Jialingjiang formation. Analysis the processing results and corresponding field geometries for Lei11 reflection at three different blocks, including 2-D old and new data with different acquisition parameters, and 3-D data with prestack and poststack migration. We suggest that it is imperative to select suitable acquisition and processing techniques for structure characteristic of Leikoupo formation. It must take 3-D seismic exploration and prestack migration when structure is consists dense folds with low highness, it is enough to take 2-D normal seismic acquisition and processing techniques when the structure is relative simple.

川中地区中三叠统雷口坡组地层在其内部和下伏嘉陵江组的盐岩、膏岩等软地层的盐底辟作用以及区域 上的挤压作用共同影响下,形成了以坡坪式逆冲断层为主,密集的低幅度断弯褶皱相伴生的薄皮逆冲构造样式, 使得该区多个区块的地震资料构造成像质量不理想。雷一1亚段的白云岩层段与其上下围岩的波阻抗差较小, 地震反射表现为弱反射特征,雷一1顶面反射品质较差,反射层位难以准确识别,构造解释的难度很大。为此,在 3个不同区块内,对雷一1反射的目标处理结果及相应的采集参数进行了包括不同采集参数的二维新、老资料, 三维叠前、叠后偏移处理等在内的对比分析。结果表明,应根据雷口坡组地层的构造特征选择采集和处理技术, 即当构造形态呈密集的低幅度强烈褶皱和断裂时,必须采用三维地震勘探及叠前偏移等技术;当构造较简单时, 采用二维常规采集处理技术,即可获得较高品质的资料。

Constraint joint inversion of magnetotelluric and seismic data versus simulated annealing algorithm is used in Western Asia. The studied area was difficult to seismic prospecting, construction and the reflection quality was not good especially in the complicated piedmont structural are-a. Therefore, joint inversion technique was carried out u-sing CEMP data, seismic data and gravity & magnetic data as well to solve the distribution of deep target and basic structural features. Basic physical-geological models of the studied area were built in accordance with physical properties study. Then the constraint synchronous joint inversion technique of magnetotelluric and seismic data versus simulated annealing algorithm and the sequent joint inversion using gravity & magnetic data and the final integrated interpretation were put forward, the velocity, electrical, density and magnetic structures of the studied area were determined, which provided reliable bases for geological structure studies. The beneficial structural zones were also illustrated with the geology materials. The application of joint inversion was proved effective using different geophysical data.
