In viewpoint of the lack of enough basic data of foreign oilfields, under the conditions of insufficient core data, no constrains of seismic interpreted cross and fault data, the rational fine 3D geological model has been established by fine oil reservoir characterizing technique including the contrast results of individual layers, second well logging interpretation and so on.

针对国外油田多数基础资料不全，必须在缺乏取心资料，无地震解释层面及断层数据约束的条件下，运用层序地层学小层对比结果和二次测井解释等精细油藏描述技术，并插入虚拟井控制井间构造，进而建立了合理的精细三维地质模型，为该油田的储层预测及数值模拟提供了基础数据，并在实际应用中取得了良好效果。

Also the board which is setted at personal computer directly access tomemory unit without passing through floppydisk. lt is obvious that this method is, faster than floppy disk owing to entirely electric signal procedure. Ourtherwise, the ROM is eliminated the virus interfere during normal operation.

本卡插於PC上时可在开机后立即将DOS从CARD上载入记忆体内，而不须从磁碟机上载入，由於该卡无机械动作全为电子信号之处理，因此其速度较磁碟机为快，且由於ROM为仅读，故不怕ROM DISK被病毒所侵袭，不怕一开机时即遭到病毒干扰。
