Abstract: Disclosed embodiments relate to MPD well drilling methods, for example detecting fluid gains or losses even in transient conditions. For example, data relating to one or more parameter of the drilling system may be corrected/filtered using one or more technique. The corrected data can be used to calculate flowrate difference (DeltaFR), and possible fluid losses or gains in the system can be detected by calculating a virtual trip tank (VTT) using DeltaFR. In some embodiments, the technique can compensate for drillstring movement. In some embodiments, an adaptive moving average may be applied to the data to reduce noise. In some embodiments, bilateral filtering may be applied to the data, for example to address issues arising from movement of a choke in the drilling system. In some embodiments, updated baselines may be applied to remove any offset. Systems related to such methods are also disclosed.

Abstract: Disclosed embodiments relate to MPD well drilling methods, for example providing improved influx detection even in transient conditions. For example, the threshold for detecting influx may be adaptive, for example changing based on the quality of the data associated with one or more parameters of the drilling system. The adaptive threshold can then be used to detect and/or confirm influx, while taking into account possible transient conditions to minimize false alarms. In some embodiments, the method can compensate for any impact that drillstring movement may have on measured data. In some embodiments, the method can filter the data, for example to address issues arising from movement of a choke in the drilling system. Systems and devices related to such methods are also disclosed.

Abstract: Disclosed embodiments relate to MPD well drilling methods, for example allowing evaluation of whether an influx can safely be circulated out of the system. For example, a simulator can be used with parameter data from the MPD system to estimate in real time whether the influx can be circulated by the MPD system without exceeding equipment limits, and may be flexible enough to address both oil and water-based mud systems. For example, the simulator may use a multi-phase flow model to estimate the maximum pressure and maximum flowrate, which can then be compared to the equipment limits to determine whether or not the influx can be safely circulated by the MPD system. In some embodiments, the simulator can also be run iteratively to allow for optimization of the fluid circulation process. Systems and devices related to such methods are also disclosed.

The method includes: step S1: determining a size of a search window and a size of a matching window; step S2: performing linear superposition on a Manhattan distance and a Chebyshev distance to calculate a similarity between each matching block and a central block; and step S3: calculating a weight of each matching block based on the similarity, and calculating a current denoising result based on each matching block and the corresponding weight. The method can basically maintain a noise denoising effect of original NLMeans, and enable the NLMeans to be easily implemented on an FPGA.
