【摘要】 在地震地质条件复杂地区,用单一的地震方法解决油气地质方面的问题有一定的局限性。若有针对性地使用某些非地震方法后,情况就不一样了。在GY凹陷应用高精度重力勘探成果,分析了全凹陷区域构造特征和油气地质情况,在此基础上查证、落实了下第三系内局部构造,并对凹陷含油气远景及地震地质条件进行了评价,取得了良好的地质效果。显示了使用非地震综合物探方法解决石油地质问题的能力与作用。更多还原

【Abstract】 In the area with complex seismic geology condition,the solutions of petroleum geologic problems are limites by the unique use of seismic survey If some non-seismic gcophysica survey was applicd objcetivcly,the situation would bc improved. In GY sag,bused on high aceuracy gracity data, we analysis the regional structure featurcs and pctrolcum geologic information, then delineatc thc local structurcs and cvaluatc hydrocarbon potential and scismic geology conditions. The resnlt is satisfied in geo]ogy,and it indicatcs thc ability and effect of jntegratcd gcophysical survey in solntion of petrolenm geologic problems.更多还原
