Medication thermal energy water circulating blanket

The invention discloses a medication thermal energy water circulating blanket which comprises a liquid heat radiation circulating loop structure formed by connecting a dialysis macromolecule energy pipe, a constant-temperature furnace, a minitype mute water pump and the like, the dialysis macromolecule energy pipes is evenly arranged on a cotton blanket body to cool the cotton blank body. According to the medication thermal energy water circulating blanket, needed medicinal materials only need to be placed on a filter screen in the constant-temperature furnace, nutrition ingredients of the medicinal materials are absorbed by water, agentia is pumped to the dialysis macromolecule energy pipes to circulate, the dialysis macromolecule energy pipes distribute the nutrition ingredients of the agentia to a bed blanket slowly to be absorbed by a human body through pores of the human body at this moment, and therefore people can be moisturized by the water and can obtain the nutrition effect of the medicinal materials in sleep, people can feel warm and comfortable, and can maintain beauty and keep young, and the special effect of preventing diseases can be achieved. Heating, circulating and heat preservation in the whole process are automatically controlled, the medication thermal energy water circulating blanket is simple in structure, low in cost, convenient to use and good in market prospect and has good market prospects, and social benefits and economic benefits are considerable.

Centrifugal casting high-speed steel composite roll and manufacture method thereof

The invention relates to a centrifugal casting high-speed steel composite roll and a manufacture method thereof and belongs to the field of casting. The composite roll is composed of outer layer high-speed steel, middle layer graphitic steel and core high-strength nodular cast iron by centrifugal compounding. The centrifugal casting high-speed steel composite roll is based on the conventional high-carbon high-vanadium high-speed steel roll, the content of vanadium is appropriately reduced, niobium is added at the same time, and the Nb / V is controlled to be 0.3 to 0.5 so that Nb and V form complex carbide (V, Nb) C so as to avoid forming segregation under the action of centrifugal force. A roll core of the high-speed steel composite roll adopts high-strength nodular cast iron, and a multivariate graphite steel middle layer is poured between an outer layer and the roll core for preventing interfusing elements of Cr, B, and the like which cause embrittlement when the nodular cast iron is poured to be fused with the outer layer high-speed steel. Microalloying processing for refining the organization is carried out on a roll surface high-speed steel material and the middle layer graphitic steel so as to achieve the purpose of improving the thermal cracking capacity of the roll material. The centrifugal casting high-speed steel composite roll has high overall performance, long service life and good economic benefits.

Determining method for surveying reserves of hypotonic clastic rock oil-gas reservoir

The invention relates to a determining method for surveying the reserves of hypotonic clastic rock oil-gas reservoir positioned on a clastic rock oil (gas) geological reservoir enrichment boundary, comprising the following steps of: carrying out statistical regression on the daily produced oil-gas data and water data of the traditional testing oil well and the traditional testing gas well and thecorresponding physical data, oil-bearing data and electrical data of an oil layer to determine the physical lower limit value, the oil-bearing lower limit value and the electrical lower limit value of an oil-gas layer, which correspond to industrial oil-gas flows; determining the minimum values of output and a sand body thickness according to the relationship between an effective thickness and test oil output and between the sand body thickness and test production; determining the area boundary of the oil-gas reservoir by using a sandrock thickness isoline method and an effective thickness isoline method; and calculating the reserves of the hypotonic clastic rock oil-gas reservoir. The invention solves the problem that the oil-bearing area of the traditional hypotonic clastic rock oil (gas) reservoir is extrapolated depending on artificial well points, is convenient to apply in the calculation of the reserves, can not only be used for more accurately calculating the reserves of oil (gas) reservoir, but also furthest save the exploration discovery workload and reduce the discovery cost of ton reserves, thereby enhancing the economic benefits of oil-gas exploration and development.
