Abstract:Even in the same block, the difference in lithology distribution is small, but there is still a big difference in the distribution of the central wells and the edge wells in the block at the same level of depth. This is because we need to find data points of the same stratum depth instead of being disturbed by data points of horizontal depths. According to this problem, we propose two GMM algorithms based on EM: multi-layer GMM and two-layer GMM. The feature of multi-layer GMM is that even if there are edge we… Show more
