The invention relates to an efficient multi-thread log writing-in method. An interface used for an application program, a front terminal for generating log information and a rear terminal responsible for writing the log information into a local file are used. The efficient multi-thread log writing-in method includes the steps that (1) buffering regions of the front terminal and buffering regions of the rear terminal are initialized, (2) the front terminal is responsible for filling the buffering regions of the front terminal with the log information, (3) the rear terminal writes log data of the buffering regions of the rear terminal into the local file, (4) after the buffering regions of the front terminal are filled through writing, the buffering regions of the front terminal and the buffering regions of the rear terminal are exchanged, the rear terminal writes the data of the buffering regions of the rear terminal into the local file, the front terminal fills the buffering regions of the front terminal with the new log information, and the steps are circularly executed in this way. According to the efficient multi-thread log writing-in method, obvious performance losses can be avoided when thousands of logs are written per second, the scene that a large number of log data are generated through one course can be dealt with, normal executing flow is not blocked, and lock contention in a multi-thread program is avoided.

The invention discloses a well pattern rebuilding method and device for the water-injection development of an old oil field. The method comprises the steps that various factors for influencing well pattern arrangement are taken into account, and mesh parameter data in geologic modeling and numerical reservoir simulation computed results are stacked and computed to obtain parameter distribution of series of strata; the mesh comprehensive evaluation index of the series of strata is computed, and a comprehensive evaluation index distribution diagram of the series of strata is obtained; well patterns are arranged on the comprehensive evaluation index distribution diagram of the series of strata according to different well pattern types, well positions are adjusted according to the characteristics of the comprehensive evaluation index distribution diagram, and initial well pattern arrangement schemes are obtained; for each initial well pattern arrangement scheme, old wells are searched for around the signal wells, and whether the oil wells are utilized is determined according to well conditions and an injection-production relationship; each well pattern arrangement scheme formed finally is evaluated, and the relatively-optimal well pattern arrangement scheme is selected according to the well pattern control degree and a recovery efficiency index. The well pattern rebuilding method and device for the water-injection development of the old oil field can meet the well pattern arrangement requirements of old oil fields in the secondary development process.

The invention discloses a method for releasing a port of carrier-grade network address translation equipment. According to the method, a carrier-grade network address translation device is involved; the carrier-grade network address translation device comprises a network address translation module, a port release module, a user address mapping table, a local translation mapping table, an idle port list and a local session mapping table; the carrier-grade network address translation device releases the port according to the occupation situation of the port accessed by a user; and the carrier-grade network address translation device executes the following steps on an arrived message: (a) inquiring the local translation mapping table; (b) inquiring the user address mapping table; (c) releasing the port; and (d) processing the local session mapping table.

The invention discloses a wireless metropolitan area network (MAN) safe access method, comprising the steps of: completing security capability negotiation between a GW (Gateway) and an SS (Subscriber Station); performing first configuration on a BS (Base Station) by the GW, and closing a controlled port corresponding to the SS by the BS; completing an identity authentication based on WMAN-SA (Wireless Metropolitan Area Network-Security Access) by the GW, the SS and an AS (Authentication Server); negotiating to obtain a session key TEK (Traffic Encryption Key) by the GW and the SS; performing second configuration on the BS by the GW, and opening the controlled port corresponding to the SS by the BS; and encrypting and deciphering business data by using the TEK by the GW. In the invention, the access GW is used for controlling and managing the WMAN-SA of the BS, which can meet the requirement on large-scale deployment of the WMAN-SA.
