Method for constructing salt-cavern gas storage base

The invention relates to a method for constructing a salt-cavern gas storage base. The method comprises the following steps that 1, an L-shaped horizontal well is drilled from the ground, wherein theL-shaped horizontal well comprises a vertical well segment, an inclined well segment communicated with the vertical well segment and a horizontal well segment communicated with the inclined well segment, and the horizontal well segment of the L-shaped horizontal well is located in the middle of a salt layer; 2, an upper casing pipe column is disposed on the vertical well segment and the inclined well segment, a fixing structure for fixed connection and sealing is adopted between the upper casing pipe column and a stratum, and a combined pipe string is placed in the horizontal well segment; 3,a flushing pipe column is placed into the combined pipe string, water is sprayed to the surrounding salt wall through a mesh hole of a screen pipe in order to impact the salt wall to form melting chambers, jetting nozzles are located from far to near, each screen pipe sub-segment is adopted for melting the salt layer, finally a series of the melting chambers are formed, and thus the salt-cavern gas storage base is obtained. According to the method for constructing the salt-cavern gas storage base, the construction speed is high, the capacity is large, and the comprehensive cost is low.

Method for detecting roundness and sphericity of inner sphere of outer ring of knuckle bearing

The invention relates to a method for detecting the roundness and the sphericity of an inner sphere of an outer ring of a knuckle bearing. The method comprises the following steps that (1), different sections of the inner sphere of the outer ring of the knuckle bearing are selected; (2), two pairs of measurement sensors which are perpendicular to each other and are located on the same plane are adopted to measure the diameter of each section for many times; (3), the diameter data obtained by measuring the same section for many times are averaged, the measurement values and the average value are compared and analyzed, and the roundness of the sections of the inner sphere of the outer ring is judged according to the error; (4), according to the diameter data of the different sections, a radian is calculated, an average value is obtained, the radian values and the average value are compared and analyzed, and the sphericity of the inner sphere of the outer ring is judged according to the error; (5), the percent of pass of the knuckle bearing is determined; (6), the error is analyzed. The method for detecting the roundness and the sphericity of the inner sphere of the outer ring of the knuckle bearing has the advantages that non-contact measurement is achieved, and the surface of the knuckle bearing is not damaged; the application range is wide, operation is easy, and the safety is high; the detection precision and efficiency are high, and development value is achieved.

Method and system for identifying high-temperature hydrothermal geothermal field in volcanic region

ActiveCN112180462AInnovativeQuick initial identificationGeological measurementsLithologyQualitative analysis
The invention belongs to the technical field of volcano region information identification, discloses a method and a system for identifying a high-temperature hydrothermal geothermal field in a volcanoregion, and provides a quantitative index for judging whether the high-temperature hydrothermal geothermal field in the volcano region is suitable for hydrothermal power generation or not. The quantitative index is less involved in the existinggeothermal field exploration and identification research, and has certain innovativeness. Firstly, which geothermal field type is preliminarily judged fromearth surface thermal display, then the geothermal field type to which the geothermal field type belongs is further quantitatively judged and an underground exploration range is delineated through gravity and magnetic anomaly and a geodetic heat flow value, then fault development condition identification is carried out, and quantitative analysis of reservoir stratum lithology and quantitative analysis of resistivity measured by magnetotelluric are combined; and a corresponding type of geothermal field range suitable for hydrothermal power generation is finally delineated. Multi-parameter combined judgment, quantitative analysis and qualitative analysis are combined, and whether the geothermal field is suitable for hydrothermal power generation or not is judged as accurately as possible.
