The invention discloses a gas logging oil-gas-water identification method based on parameter reconstruction. The method comprises the following steps: through average values of C1-C8 of an oil testing well section, establishing two reconstruction parameters of two FLAIR gas loggings, that is, a TCZS parameter and a C7-8bC5-6 parameter; then using the C7-8bC5-6 parameter as a x-coordinate, and the TCZS parameter as a y-coordinate, and field oil testing result data, establishing a plate, determining limits of various fluid properties in the plate, and finally verifying on site. The method solves problems of difficulty of depending on software identification and hardware developers, enriches existing technical means, and improves oil-gas-water layer identification efficiency of a well, reduces identification difficulty, and improves technical level of field staff.

The invention discloses a heat pipe, a manufacturing method of the heat pipe and equipment comprising the heat pipe, mainly relates to a capillary core of the heat pipe and a manufacturing method of the capillary core, and belongs to the technical field of heat conduction. According to the manufacturing method, a positioning tool and a metal net are mainly used, metal powder is arranged and limited in a specific space position in a pipe shell, and the technical problems that in the sintering process in which a traditional method is adopted, the metal powder is bonded with a core rod, when thecore rod is pulled out after sintering, the capillary core is prone to damage, and even a waste product occurs, and the technical problems that core rod is used for separating the reducing atmospherefrom the metal powder, so that the reducing effect is poor, secondary sintering is generally needed, and the energy consumption and the thermal pollution are large can be comprehensively or correspondingly solved; and the technical situations that the capillary core of the sintered layer is damaged due to the deformation processes of bending, flattening and the like can be relieved or avoided, andthe process route in which bending is carried out first, and then sintering is carried out can be realized. The method is applied to manufacturing of the heat pipes (including hot columns and ultra-thin heat pipes). The heat pipe is applied to equipment or a device requiring heat transfer or heat dissipation through the heat pipe.

The invention provides a preparation method for a high-concentration compound organic pollution restoration agent. The preparation method includes the steps of preparing, optimizing and modifying sodium-type bentonite and forming modified bentonite. The preparation method is simple and economical, the prepared restoration agent has outstanding performance of adsorbing various organic pollutants and particularly existing high-concentration organic pollutants, is reliable in adsorption, stable in nature and environmentally friendly and is an economical high-practicability restoration agent. The restoration agent is particularly suitable for treating and restoring high-concentration compound organic pollution, for example, severe organic pollution soil, organic waste water and refuse landfill organic leachate.

The invention discloses a method for oil-gas-water identification based on physical property and gas logging parameter intersection. The method comprises the following steps: reading the C1-C8 average of test well sections by collecting site gas logging data, well logging interpretation porosity data and oil testing data, performing parameter reconstruction, obtaining a TCS parameter, building a plate, determining limit of various fluid properties in the plate, performing on-site verification, and performing popularization and application in more wells on the site if no error occurs. The method solves the problem of immoderate reliance on software identification and hardware developers, enriches existing technical means, improves well drilling oil-gas-water layer identification efficiency, reduces identification difficulty, improves technical levels of field workers and also has the effect of promoting later-period oil-gas-water identification and instrument popularization.
