摘要
井中化探技术作为一种新的油气监测和早期评价的地球化学录井技术越来引起人们的关注。东海某探井的井中化探成果表明，各指标在纵向的梯度变化呈上低下高井与地层含油气特征有关，化探异常井段与油气储层密切相关；钻井剖面的生、储、盖层在化探指标上有着不同的显示和特征。现场预测的油气层，经测试有5层获高产油气流，取得令人满意的效果。
The well geochemical prospecting method as a new technique has been paid more and more attention on oil and gas monitering and evaluating in well geochemical logging. The geochemical results of a well in East China Sea have shown that;the values of each geochemical indictor in the well geochemical profile appear vertical gradient variation (higher values in the lower part and lower in the upper part) and relate to the oil and gas-bearing formation;geochemical anomalies relate closely to the reservoir:and the geochemical indicators have different features for source rock. reservoir rock and cap rock in the well profile. The well geochemical prospecting has obtaind good results in which five formations have been tested with highly-productive oil and gas flows.
