1.2.9 Resistivity Editor电阻率编辑器
The Resistivity Editor window is divided into a spreadsheet and a graphic display: To adjust the division between the graph and the spreadsheet, drag the border between them. The widths of the spreadsheet columns may be adjusted by dragging on the column borders in the header row. The graph and the spreadsheet are separately scrollable. To position the spreadsheet to a specific depth, double-click the left mouse on the graph at the desired depth. Up to four (4) resistivity traces can be displayed at a time. To set up the resistivity editor, right-click the mouse anywhere in the window and select Resistivity Display Setup from the popup menu that appears. This will display the resistivity options dialog box: 电阻率编辑窗口可以分为表格显示和图形显示两种。可以通过拖动鼠标调节各栏的宽度。通过在图形上双击鼠标左键可以相应地在表格中找到对应深度。可以同时显示四个电阻率运行轨迹。如要设置电阻率编辑器,在该窗口任一处右击鼠标再从弹出的菜单中选择“电阻率显示设置”。这样会出现电阻率选项对话框。

数据查看及监控装置II的操作
Logview II performs the following functions: 数据查看及监控装置II执行以下功能:
? Allows the user to configure a tool using the qMWDCnfg utility and sets
up the downhole recorders using MemoryIO before the tool is run into the hole.
允许用户安装能使用qMWDCnfg的仪器并设置在仪器下钻前使用
MemoryIO井下记录器.
? While running into the hole, allows the user to create a database for the
well by entering the appropriate information for the well identification and tool run
.当下钻时,允许用户针对井况和仪器运转通过输入恰当的信息创建数据
库。
? Before the tool starts pulsing LWD data to the surface, the depth
tracking system is set up and calibration is performed.
在仪器向地面开始脉冲传输LWD 数据前,深度追踪系统已设定并且执行井
深校定。
? When depth tracking is working, the user connects Logview II to the
qW32Server and starts logging depth data to the database.
当深度追踪系统开始工作时,用户须将数据查看及监控装置连接到qW32服
务器上并把测井数据传输到数据库中。
? The surface receiver, MPRx, decodes transmitted data and forwards it
to the qW32Srver, then to Logview II where the data is logged to the database.
地面接收器,MPRx,解码已传输的数据并进而输送到qW32服务器上,然后
输送到数据查看及监控装置,在那里数据被记录在数据库中。
? ? Monitors incoming data via the various editor windows. 通过不同的编辑窗
口监控录入数据
? ? Performs data editing either as it is received or at a later time. 在一接收到
数据时或过一段时间间隔之后执行数据编辑
? RTView allows the user to view a real-time log plot实时监控允许用户查

recorded data into the database.当仪器运转完毕并取回地面时,MemoryIO 内存从记录器中下载数据,然后数据查看及监控装置把记录的数据输入数据库。
? Using the recorded data, the log is previewed and plotted; any further
editing is performed.通过运用已记录的数据,测井记录可以预览和标绘,同时还可执行进一步的编辑。
? When the tool goes back into the hole, Logview II creates a new tool
run in the database. Tool run data is updated as necessary. 当仪器重新下井,数据查看及监控装置会在数据库中创建一个新的仪器运转记录。仪器运转数据会必要的进行更新。
? The depth spacing filter creates evenly spaced data sets from the
completed run, plots data on the log and then uses the LAS export function to write the data in an LAS 2.0 format file.
深度间隔滤波器在整个仪器运转过程记录中的测图数据上创建等同间隔
的数据设置,然后使用LAS输出功能在LAS2.0形式文档上书写数据。
IMPORTANT:
Logview II is organized around the principle that each database contains the data from one and only one well,
organized into one or more tool runs. DO NOT create a new database just because a new tool run is beginning!
重要事项: 数据查看及监控装置围绕以下原则工作,即每个数据库保存的
是一口井且仅为一口井的数据,可包括一次或多次的仪器运转。不可以在每次仪器运转时都创建新的数据库。 Logview II does not need to be actively connected to the qW32 Server to be used. If the section being drilled is not of interest, the user can disconnect from the qW32Server or exit Logview II in order to keep the unwanted data from the
database. However, even if receiver or pulser problems prevent transmitted data from being properly decoded, it is important that Logview II be connected to the qW32 Server to receive depth updates, so that recorder data may be properly depth tagged when it is imported after the tool run is complete.
数据查看及监控装置不需要总是与qW32服务器连接工作。如果钻井井段并不重要,用户可以断开与qw32server的连接或者退出Logview目的是避免不需要的数据进入数据库。然而,一旦接收器或脉冲器出现的问题妨碍了传输上来的数据的正常解码;那么Logview就应该与qw32server连接从而接收更新的深度数据,这样在仪器运转完毕后输入记录数据时,这些数据能够准确地体现标记的深度。

1.2.7.5 Run Data运行数据
The Run Data screen has the following general appearance. Note that the width of the columns in the spreadsheet may be adjusted by dragging on the column borders in the header. The row height is not adjustable.运行数据界面轮廓大体如下。各栏的宽度是可以调节的。每个格的高度是不可以调节的。
The data in the Description, Start Time, End Time, Elapsed Hours, Start Depth, and End Depth fields is automatically generated and maintained by Logview II and cannot be modified; all other data is supplied by the user. Fields filled with dashes indicates that no data is available. When a new database is created, the default entry for Run 1 is automatically created, and the user supplies the correct information. After the first tool run is complete and the tool is ready to go into the hole again, a new run should be created by clicking the New Run button in the upper right corner of the Run Data screen. The new run will be initialized using the sensor offset, tie in, and scale factor data from the previous run. The user should edit this data where necessary. Ideally, the correct sensor offsets should be set before the data is acquired for a run. However, if an offset is entered incorrectly it can be corrected at any time and Logview II will automatically adjust the sensor depths.”描述,起始时间,截止时间,关闭时间,起始深度,截止深度”等表格是自动生成的并保存在Logview II中不可被更改;所有其他的数据由用户提供。带有小点的表格表明无可利用的数据。当创建了新的数据库时,Run 1也被自动创建,用户需提供正确的信息。在第一次仪器运转后并且仪

器准备再一次下钻时,通过点击运转程序界面右上角的New Run键创建一个新的运转程序。这个新的运转程序将沿用上一次的传感器偏差,范围因素等数据。用户应在必要的地方输入数据。理论上,正确的传感器偏差应在运转数据获得前设置。然而,如果输入不正确的差值它可在任一时间得到修改而且Logview II将自动调整传感器深度。
