Cylindrical permanent magnet linear motor

Номер: CN103441639A

The invention discloses a cylindrical permanent magnet linear motor which comprises a motor stator and a motor rotor. The shape of the axial cross section of the motor stator is a closed stator groove so as to achieve sealing of a cavity of the motor stator. The cylindrical permanent magnet linear motor has the advantages that the shape of the axial cross section of the linear motor stator is the closed groove, the structure is simple, and the cylindrical permanent magnet linear motor is particularly suitable for integrated machining production modes adopting the machining means like turning. Compared with a traditional linear motor with an inner protective cylinder, the closed groove-shaped linear motor stator is less in equivalent air gap, and therefore electromagnetic force generated by unit current under the same condition is larger.

The invention discloses application of a single surfactant N-alkyl-1 and omega-alkyl-diamine (CmNnN) in ultra low permeability reservoir oil deposit chemical displacement of reservoir oil. The N-alkyl-1 and the omega-alkyl-diamine (CmNnN) can form wormlike micelle in water solution to improve injected water viscosity and be favorable for improving crude oil recovery rate. An oil displacing agent is a single surfactant system, enables tension of crude oil/ water interface to be reduced to ultra low point, overcomes chromatograph effect and guarantees stable oil displacing efficiency.

Принадлежит:

The invention discloses a segmented fracturing method of a low-permeability oil reservoir horizontal well and belongs to the field of segmented transformation of the low-permeability oil reservoir horizontal well. The method comprises designing at least one construction unit according the geological data of the horizontal well, wherein every construction unit comprises three construction segments; separating the three construction segments through jetting and fracturing the first construction segment and the third construction segment on both sides of the construction unit; and fracturing the second construction segment in the middle of the construction unit. According to the segmented fracturing method of the low-permeability oil reservoir horizontal well, by fracturing the first construction segment and the second construction segment on both sides of the construction unit at first, the stress on the second construction segment in the middle of the construction unit is changed to enable ...

The invention relates to a high-broken-pressure stratum horizontal well sectional-fracturing method for well cementation and completion of a casing. The high-broken-pressure stratum horizontal well section-fracturing method includes firstly perforating and fracturing all stratum layers by means of the hydraulic jetting fracturing technology for the horizontal well; then laying down a packer for fracturing a tubular pile sectionally and fracturing the stratum layers not fractured by the hydraulic jetting fracturing technology, wherein the maximum annular pressure of a well mouth is not higher than 45MPa during perforating and fracturing the tubular pile by hydraulic jetting. Hydraulic perforating and fracturing of the lower-broken-pressure stratum layers are integrated directly, construction requirements for high-broken-pressure stratum layers are met on the premise of keeping the requirements for mating of the well mouth and steel level of the casing without change or lower; for the high-broken-pressure ...
