实际钻进 meaning in Chinese

actual drilling

This paper , based on normalizing well logging data while drilling and correcting depth into true vertical depth and calculating reservoir parameters and etc , combining the practical ease of mobei oilfield , extracted logging and geological pattern characteristic of target oil - gas formation and geosteering mark formation , and used bp neural network and regressive analysis to create predicting mode of geosteering parameter to build relevant contrast curve ; adopted geometry geosteering method to fix on die drilling direction of bit upper and declination , the position in reservoir , to judge the real drilling case . all finely solved the problem to follow the geological target while drilling for three horizontal well these methods improve the drilling horizontal well ability by using the techniques to follow the geological target while drilling , and then it is convenient and practicable
本文在开展随钻测井资料的标准化和斜井校正及储层参数解释与含流体性质判释等工作的基础上，结合研究工区莫北油田的实际情况，提取了目标油(气)层和导向标志层的测井地质模式特征，并采用bp神经网络法和回归分析法建立了地质导向参数的预测模型、构造了相应的对比曲线；采用几何导向法确定钻头上下倾钻进方向及其在目标层的位置，以判断实际钻进地层情况，很好地解决了研究工区三口水平井的随钻跟踪地质目标的问题。
