钻进方向 meaning in Chinese
direction of drilling
Examples
- In order to geosteering , log - geology model of target formation should be built according to logging data and the interpreting result of wells nearby . geosteering parameters model is created to build simulative curves . compared these curves with logging curves , the position and drilling direction of the bit can be found combined with the concrete geological situation
要实现地质导向，首先要根据邻井的测井资料及其解释结果建立目标层测井地质模式，然后通过建立地质导向参数的预测模型构造相应的模拟曲线，将模拟曲线与实测曲线进行对比，结合具体地质情况，确定钻头在目标层中的位置及其钻进方向，及时调整井眼轨迹，使其始终保持在目标层中物性最好的部位。 - This study made a conclusion ? amely in order to realize following the geological target while drilling , on the basis of making a better geological and drilling design for horizontal well , we must make full use of mwd , lwd and integrate logging to carry out lithfacy identifying in real time , the lwd interpretation and formation evaluation , to set up geological model of target formation , to select geosteering marked formation and compare simulative curves with lwd curves f to fix on the drilling direction of bit upper and declination , the position in target oil - gas layer , to revise borehole track in real time , to make it extend in reservoir better interval as possible
研究认为，在做好水平井地质设计和钻井设计的基础上，要实现随钻跟踪地质目标钻井，必须充分利用随钻测量、随钻测井和录井等资料，从实时岩性识别、随钻测井解释和地层评价、目标层地质模型建立、导向标志层的选取及模拟曲线对比等方面入手，确定钻头上下倾钻进方向及在目标层中的位置，以实时调整井眼轨迹，使其尽可能在储层物性较好的部位延伸。 - 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。
