摘要： A method for determining a stratigraphic anomaly in a subsurface of the earth includes receiving raw data x, assigning the rock samples to corresponding stratigraphic units of the subsurface, transforming the raw data x to a centred log-ratios clr(x) dataset, calculating p-values with a pairwise sum rank test between populations of the centred log-ratios clr(x) dataset, selecting a set of fingerprint elements from the elements of the rock samples, converting raw concentrations corresponding to the set of fingerprint elements to isometric log-ratios ilr data, determining a number of ilr sub-populations within each stratigraphic unit, applying mixture discriminant analysis to the isometric log-ratios ilr data, using the ilr sub-populations to calculate posterior probabilities of the rock samples, and identifying the stratigraphic anomaly based on the posterior probabilities.

摘要： A downhole rock debris extraction system is provided. The downhole rock debris extraction system includes a downhole marking component, a ground control component and a ground detection and extraction component. The downhole marking component is arranged at a drill bit for underground excavation or near the drill bit, and is configured to mark rock debris by spraying different types of markers in real time during the underground excavation performed by the drill bit; the ground detection and extraction component is configured to detect the types of the markers on the rock debris; and the ground control component is configured to manage and control the downhole marking component to mark the rock debris, and to manage and control the ground detection and extraction component to determine the types of the markers on the rock debris. Furthermore, a control method for the downhole rock debris extraction system is provided.

摘要： This disclosure relates to a method and a system for sequestering carbon-containing materials in underground wells. An example method includes: obtaining a material comprising a carbon-containing liquid; optionally testing the material for compatibility with an underground well; optionally adjusting a property of the material to improve the compatibility; and providing the material for injection into the underground well.

摘要： A performance evaluation device and a design method of a cement for well cementing in a penetrated hydrate layer are provided. The performance evaluation device includes an equivalent wellbore, an inner circulation system, an outer circulation system, a thermal insulation cover, a bracket, a temperature sensing system, and a cement mold. The device can simulate a true downhole situation, conduct an evaluation experiment on the heat insulation performance of a cementing cement, and conduct experiments at different temperatures with automatic temperature control. The design method is to use a low-hydration, early-strength, and heat-insulating cement slurry system during the well cementing in a penetrated hydrate layer, where the low-hydration and early-strength characteristics ensure the effective sealing of a hydrate layer during a cementing process, and the heat insulation characteristic results in low heat conductivity and thus can ensure the stability of a hydrate layer during a production operation.

摘要： Methods and systems are provided that combine NMR and IR spectroscopy measurements on a rock sample to determine data representing at least one property of the rock sample. In one embodiment, cuttings can be split into first and second lots. Results of an NMR measurement performed on the first lot of cuttings without cleaning can be analyzed to determine pore volume of the cuttings. Results of an IR spectroscopy measurement performed on the second lot of cuttings after solvent cleaning can be analyzed to determine matrix density of the cuttings. Porosity can be determined from the pore volume and matrix density of the cuttings. In another embodiment, combined NMR and IR spectroscopy measurements can be performed on an unprepared rock sample (without solvent cleaning) to characterize properties of kerogen in the rock sample and porosity. In another aspect, a method is provided that employs multi-nucleic NMR measurements to determine porosity.
