Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. Form the principle of GR logging, calculate volumes in investigating areas taken by borehole, formation, up and low shoulder beds, along with distance between center of gravity of the four unit bodies and detector. Based on the above, the weighting function of each unit body to GR signal contributions are established, thus realizing processing of GR logs with high resolution. The resistivity logging model uses "resolution matching" method to improve the resolution of the logs. After the process, PNN model is made to recognize the oil-gas-water bed. Compared with BPNN, the net work is featured swiftness, accuracy and ease of practical application.

提高密度测井曲线垂直分辨率是通过对重新组合长、短源距探测器响应的算法来提高补偿密度曲线的垂直分辨率，并加入井眼影响校正因子和相关性因子；自然伽马测井模型从基本原理出发，扣除井的影响，计算井筒、地层及其上下围岩所占探测球域体积及其重心到探测器的距离，以此建立各单元体对伽马测井信号贡献的权函数，通过权函数逐层计算不同厚度地层条件下各的单元体权因子，实现自然伽马曲线高分辨率处理；电阻率校正模型应用&分配率匹配&模型，应用低分辨率曲线提高为高分辨率曲线：曲线校正后，利用常规测井资料并且结合校正后的密度、伽马、电阻率等三个对判断油水层有利的指标，通过概率神经网络模型识别储层流体性质，较以前的模型，不仅极大的提高识别正确率，同时与普通神经网络相比较，提高了网络的运行速度和实用性。

During the air phase, the vertical displacement of body gravity of one-foot jump was significantly smaller than two-foot jump.
