The manufacturer of PDC for gas drilling bit tells you that we have found that drilling with PDC bits is sometimes quite fast, which makes it difficult for cuttings logging to keep up with the drill bit. The small cuttings particles make it difficult to name the lithology. The manufacturer of PDC for gas drilling bit tells you that the relative lithological response during drilling is sometimes not obvious, and the difference between sand and mudstone is not big, and even the opposite phenomenon of sand and mudstone drilling occurs, so that the use of drilling time curve to divide, return to the lithology and stratification is not obvious. No matter how accurate. Therefore, the traditional methods of naming cuttings and homing by layer during drilling are difficult to meet the needs of geological logging. More, more intuitive and fast logging parameters must be found to be used in geological logging, and stratigraphic profiles can be established quickly. Meet the needs of modern logging.
The manufacturer of PDC for gas drilling bit tells you that sometimes the use of a microscope is beneficial to the description of lithology. When drilling with a PDC bit, the cuttings samples are fine. Sometimes it is hard to see the rate of change of the rock samples and their composition and structure with the naked eye. Sometimes although they are all sandstone, their drilling parameters have considerable changes. The reason is sandstone particles. Different cements and their cement types, the PDC for gas drilling bit manufacturer tells you that some sandstones have high drilling time and weight on bit, and the drilling parameters have no obvious indication. At this time, you have to use a microscope to observe the new emergence. The properties of cuttings and their cementation and analysis of cementation types.
The manufacturer of PDC for gas drilling bit tells you that under normal circumstances, the lithology of gray matter and siliceous cement is very hard and poor in drillability, while mud cement has good drillability. The drillability of basal cement and mosaic cement is poor, while the drillability of gap cement and contact cement is better. When the PDC for gas drilling bit manufacturer tells you the specific description, based on the combination of drilling parameters, microscope observation and analysis can be used to accurately determine the lithology of the formation and its color, composition, sorting, rounding, shape, and content. , And the oil saturation of oil and gas, fluorescent display color, etc.
