【摘要】 该文对天然气田上方的重磁电等异常特征在成因上进行了分析,结合正演模型对不同规模的气田引起的重力响应幅度作了精细计算。以某气田为例,通过与已知地质、钻井和地震等对比分析,指出了重磁电等综合资料在天然气勘探方面的积极意义。综合勘探在优选目标和提高勘探成功率等领域具有重要的意义。更多还原

【Abstract】 The paper analyzed the reasons of anomalous gravimetric and electromagnetic feature above gas field, finely computed the amplitude of gravimetric response caused by different scale of gas field by forward modeling. The paper also pointed out the active meaning of gravity and electromagnetic data in the aspect of natural gas exploration by taking some gas field as an example and by correlation with known geologic, drilling and seismic data. Integrative exploration has important meaning in optimizing targets and increasing the successful rate of exploration.更多还原
