A hydraulic support device and supporting method based on extending in roadway, comprising a hydraulic support I (301) disposed at a front end of the roadway, a hydraulic support II (302) disposed ata rear end of the roadway, and a fulcrum connecting device arranged between the hydraulic support I (301) and the hydraulic support II (302) and embedded in the bottom surface of the roadway, throughthe hydraulic support I (301) and the hydraulic support II (302), the roadway is supported and protected, and through the fulcrum connecting device, the hydraulic support I (301) and the hydraulic support II (302) are connected to each other and supported by each other, and are no longer separately supported on the respective working faces, thereby improving the reliability of the roadway support.

The invention discloses a method for transforming an oil field abandoned well into a geothermal well or a brine well. The method comprises the steps that in an oil field exploitation area, an oil field abandoned well with a brine layer below an oil extraction layer or an oil field abandoned well with the bottom boundary of a geothermal reservoir layer 200 m above an oil extraction layer position is selected, a drill pipe drill rig is lowered into an oil layer casing pipe to carry out pigging, and when pigging is smoothly achieved and after it is determined that no abnormal condition exits in the well, the artificial bottom of the well is poured to seal the lower portion oil extraction layer position; a pump chamber section is transformed, and a water drainage pipe is additionally arranged on an exploitation layer; perforation construction is carried out on a technical casing pipe located on the exploited geothermal reservoir layer or the brine layer; a water filtering pipe is lowered into the exploitation layer, and for the transformed geothermal well or the brine well, sand washing well washing is directly carried out, or a water filtering pipe with a sediment pipe on the lower portion is lowered; after well washing, exploitation testing, sampling analysis and acceptance check are carried out. By means of the method, the oil field abandoned well resources are recycled, and the double effects of energy conservation and environment protection, and economic benefits of recycling of the oil field abandoned well resources are achieved.

The invention relates to a steam-water separation device of a steam-injection boiler, in particular to a steam-water separator of a horizontal type steam-injection boiler. The steam-water separator of the horizontal type steam-injection boiler solves the problems that when a steam-water mixture of the dryness less than 80% is injected into a heavy oil mine, the oil recovery efficiency is low, the oil recovery requirements can not be met, large scale can not be achieved, and maintenance is inconvenient. A steam outlet pipe connector and a spray water outlet pipe connector are communicated to a barrel, a cross partition board is installed on the inner wall of the bottom of the barrel, a corrugated board dryer is installed on the inner wall of the top of the barrel, diversion devices, primary separator bodies and secondary separator bodies are arranged inside the barrel from bottom to top, the lower ends of the primary separator bodies are connected with the diversion devices, the upper ends of the primary separator bodies are connected with the secondary separator bodies, the two obverse faces of the two diversion devices on the left side and the two diversion devices on the right side are respectively connected with the barrel through a bent board, the two reverse faces of the two diversion devices on the left side and the two diversion devices on the right side are respectively connected with the barrel through an arc board, and water return pipes are communicated with the lower end of the corrugated board dryer. According to the steam-water separator of the horizontal type steam-injection boiler, large scale is achieved, and maintenance is convenient.

A method of reservoir simulation comprising constructing a hierarchical logic diagram (10) having one or more components. Each component represents a set of programming code. The method further includes converting the hierarchical logic diagram into programming code (20) configured to manage a simulation of the reservoir (40).

The invention discloses an ionic type rare earth ore in-situ leaching and mining method. The method includes the steps of extracting ionic type rare earth ore liquid from a shallow mine layer and extracting ionic type rare earth ore liquid from a deep mine layer. The method has the advantages that the mining process is simple, mining is safe, the mining amount of the ionic type rare earth ore liquid is improved, seepage pressure can be monitored in real time, and automatic control and precise liquid injection are realized.

The invention provides an explosion-free machine and an explosion-free excavator. The explosion-free machine comprises a supporting mechanism, a slewing mechanism, a rock drilling machine and a splitting machine, wherein the slewing mechanism is arranged on the supporting mechanism; the rock drilling machine and the splitting machine are arranged on the slewing mechanism along the axial direction, can be driven to concyclically slew by the slewing mechanism and can move along the axial direction of the slewing mechanism. The explosion-free excavator comprises a hydraulic driving system and the explosion-free machine, wherein the explosion-free machine is fixedly connected to the explosion-free excavator through the supporting mechanism; the hydraulic driving system is capable of driving and controlling the slewing mechanism, the rock drilling machine and the splitting machine. According to the explosion-free machine, the rock drilling machine and the splitting machine can concyclically slew, so that the splitting machine can be accurately inserted into a drill hole without manually adjusting an angle, and the working efficiency of the explosion-free machine is improved; furthermore, the explosion-free machine further has the advantages that the energy consumption is low, the exploitation quantity is high, the equipment cost is low, and the damage caused to equipment in the operation is relatively little.
