229 results about "Volcano" patented technology

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, e.g., in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core–mantle boundary, 3,000 km deep in the Earth. Volcanoes are usually not created where two tectonic plates slide past one another.

Igneous rock oil and gas exploration method and device

The invention provides an igneous rock oil and gas exploration method and an igneous rock oil and gas exploration device. The method comprises the following steps of generating crater position and igneous rock lithofacies information according to the position of an igneous rock reservoir and characteristic information; generating geophysical reflection characteristic data according to seismic facies analysis, and determining a distribution range of advantageous lithofacies; calculating a stratigraphic strike-slip distance of a deep igneous rock mechanism according to a matching relation of target stratum lithofacies of a volcanic edifice on two sides of a fracture and a corresponding relation of igneous rocks of a middle-shallow layer on the two sides of the fracture; analyzing logging response data of the igneous rocks, and generating advantageous lithology distribution information and thickness data of the deep igneous rock mechanism through natural gamma seismic inversion; acquiring a development part of the fracture of the igneous rock reservoir by using means such as deep and shallow resistivity difference inversion; and generating igneous rock oil and gas reservoir information in the development part through cluster analysis of seismic attributes and two-phase media-based oil and gas detection. By the invention, the accuracy of exploring and predicting the igneous rock oil and gas reservoir and the drilling success rate can be improved.

Preparation method and application of PD composite mineral admixture containing silica fume

The present invention provides a preparation method and application of a PD composite mineral admixture containing silica fume. The PD composite mineral admixture comprises components of, by weight percentage, 0%-95% of volcano ash, 0%-95% of mountain flour, 5%-30% of silica micropowder (silica fume) and 0-8% of gypsum, wherein the volcano ash content and mountain flour content can not be zero at the same time, and the gypsum content can be zero according to the requirements. A double-mixing admixture, a ternary-mixing admixture and a quaternary-mixing admixture are prepared by utilizing superimposed effect and interaction effect generated by a quaternary system of ''volcano ash-mountain flour-silica fume-gypsum''. Admixtures with different performance characteristics can be prepared by only adjusting the proportion of the components in the PD composite mineral admixture provided by the invention; the admixture can substitute 15%-50% of cement in concrete and mortar, with equal or excessive amount, and realizes a better effect than an admixture mixed with single volcano ash or mountain flour; and the admixture can be prepared by using local raw materials, or waste stone slag and mountain flour. Therefore, the admixture has good application prospect and promotion value in places lack of conventional admixture.
