井中油气化探异常模式及现场快速评价系统

井中化探有效地解决了近地表化探较难回答的生、储、盖及烃类垂向微渗逸等问题。使油气化探工作从近地表研究油气渗逸“痕迹”和晕圈异常进而预测目的层在平面上的位置转向直接对目的层进行研究和预测。为了适应现场快速及时预报及进一步完善井中化探方法系列，设计和编制了与井中化探方法系列相应的评价软件系统，通过在塔北某井现场检验，效果良好

GEOCHEMICAL ANOMALY PATTERNS AND A QUICK SITE EVALUATION SYSTEM IN WELL GEOCHE MICAL PROSPECTING FOR OIL AND GAS

Well geochemical prospecting has effectively solved the problems of the generating, reservoiring, sealing of oil and gas and the vertical microseeping of hydrocarbons, that are diffcult to answer for surface geochemical exploration. This makes geochemical prospecting turn from the study of seeping "trace" and halo anomalies of hydrocarbons in near surface to a direct research and prediction of the target distribution. In order to adapt a quick prediction of hydrocarbon information in time and allow the well geochemical prospecting technique more perfect, a series of methods for well geochemical prospecting and corresponding evaluation softwa system are designed and compiled. The technique has been proved to be effective by testing a well in Tabei.
