海洋油气化探干扰因素及抑制方法研究

运用相关分析的方法，对我国某海域海洋油气化探指标及干扰因素指标进行研究，指出该区主要干扰因素为海底沉积物中的碳酸盐含量。分析认为，海底油气化探指标的干扰因素主要取决于海底沉积物沉积上的差异性，在化探指标与干扰因素呈明显相关的基础上，利用线性回归方式，对该区的化探指标进行校正，消除了干扰因素的影响，提高了化探异常的可信度。

A STUDY OF DISTURBING FACTORS AND THEIR SUPPRESSION IN MARINE IIYDROCARBON GEOCHEMICAL EXPLORATION.

By means of correlation analysis, the authors studied the indicators of hydrocarbon geochemical exploration in a given sea area and their disturbing factors. It is found that the most important disturbing factor in this area is carbonate contents in sea-bed sediments. Through analysis, the authors concluded that the disturbing factors of oil-gas geochemical exploration in marine environment depends mainly on the differences of sedimentation of sea-bed sediments. Based on an obvious correlation of geochemical prospecting indicators and disturbing factors, the authors processed these indicators by means of linear regression analysis. The results showed that this kind of data processing may not only suppress efficiently the effects of disturbing factors, but increase the reliability of hydrocarbon geochemical prospecting nomalies as well.
