  geological questions
This contribution gives an example about their potential in establishing concentration gradients within minerals for geological questions.
      
Important geological questions were postulated in the 1880s and 1890s.
      


A great deal of important achievements have been gained in Qaidam basin by exploration for oil and natural gas since 1950s,the exploration practice in recent years have shown that the degree of prospecting for oil and natural gas is low,and many geological questions are still not solved.According to the integrated analysis for the evaluation,the depositional characteristics and the law of oil and natural gas accumulation Upper Palaeozoic,Mesozoic and Cenozoic strata all have great resource potentialities.Thus,the...

A great deal of important achievements have been gained in Qaidam basin by exploration for oil and natural gas since 1950s,the exploration practice in recent years have shown that the degree of prospecting for oil and natural gas is low,and many geological questions are still not solved.According to the integrated analysis for the evaluation,the depositional characteristics and the law of oil and natural gas accumulation Upper Palaeozoic,Mesozoic and Cenozoic strata all have great resource potentialities.Thus,the exploration for oil and natural gas must be enhanced,and great breakthrough will be gotton in the future.

经过40多年油气勘探开发工作,柴达木盆地取得了许多重要成果。但是,近年来的勘探实践表明,全盆地的油气勘探程度仍然很低,许多地质问题有待深入认识。从盆地演化、沉积特征及油气富集规律的整体来看,上古生界、中生界及新生界都具有很大的资源潜力。因此,必须进一步加强油气勘探,力争在近期获得新突破。

Much more attention is paid to walkaway VSP in view of its unique observation form and its importance to solve geological questions.Walkaway VSP forward modeling is an effective tool for theoretical study and wave field identification.Based on the ray theory,a walkaway VSP ray tracing modeling program has been developed,which could model not only p wave and s wave alternativly but also composite wave field of p and p sv wave.It can be used to complicated structure.Some synthetic examples have been proven...

变偏移距VSP方法以其独特观测方式及解决地质问题的能力而倍受人们关注。变偏移距VSP正演模型是理论研究、波场识别的得力工具。本文以射线理论为基础,研制了变偏移距VSP射线追踪模型程序,它既可以单独模拟P波、S波,也可以模拟P、P-SV波的复合波场,可以适应复杂介质情况。给出的几个例子,说明本方法具有快速、灵活、实用的特点。
