2、CORE, such as layout and shooting. These lessons will show a couple of the variety of layout and shooting options. Another lesson will feature the new capabilities of MESA CORE version 5.0. Here the user will put to use the Advisor and Spreadsheet Capabilities now available. 第一節(jié)：檢波點(diǎn)與炮點(diǎn)設(shè)計(jì)首先用戶建立一個(gè) 8 平

3、方千米的 3 維設(shè)計(jì)。各種參數(shù)分別為：檢波器道間距為 220，檢波器線距為880，炮間距為 220，炮線間距為 1320，一個(gè) 8 x 36 網(wǎng)格用于編制程序。教程將展示如何用自動(dòng)模版中心來(lái)編制探測(cè)計(jì)劃的一種方法。此設(shè)計(jì)的編輯和坐標(biāo)將用標(biāo)準(zhǔn) ascii 格式輸出。Lesson #1, Station and Shot Layout:In the first lesson the user will be creating an 8 square mile 3D survey. The Parameters will be Receiver Interval 220, Receiver Line

4、 Interval 880, Source Interval 220, and Source Line Interval 1320. An 8 x 36 patch size will be used to shoot the program. The purpose of the lesson is to demonstrate one of the methods used to layout a survey as well as shoot the program with the automatic template centering. Some editing of the de

The user can also choose to generate sail lines to the Design Window to use all the diagnostics available with MESA Core v5.第五節(jié)，個(gè)體模板Lesson #5, Unit Template:This lesson is to have the user become familiar with the Unit Template layout option. The exercise demonstrates how to define

10、a template that will create a survey and shoot it simultaneously while fitting it to a defined area.TUTORIALS 39 第六節(jié)，連續(xù)滾動(dòng)放炮Lesson #6, Sequential Roll Shooting:This lesson is designed to give a brief example of the Sequential Roll Shooting option that is available in MESA 5.0. Sequential Roll Shootin

STARTING A NEW PROJECT: Start the Mesa Core application by double clicking the Mesa Icon on the PC as shown above, or typing “Mesa” at the command prompt on Unix. The following screen will appea

12、r and Mesa will be in the design window. After starting the Mesa Core version 5 application the following Pull Down menus will become available. Become familiar with these menu selections as they will be referred to and used in more detail throughout the lessons. The Pull Down menus are File, Layout

13、, Bin Analysis, Display, Utilities, Output, Advisor, System 2000 and Help.40MESA CORE VERSION 5.0 USER MANUALThe user is in a blank design window, and the design window is labeled “”. At this point the user can assign the project a name only after performing an action.The user needs to perform an ac

Neither the “Save Database” nor the “Save As New Database” from the “File” pull down menu will be active until an action has taken place. Functions in Mesa can be performed without supplying a project nam

15、e. If this is done, when the user exits the program, a prompt as shown below will appear. The user then has the option to “Save” any changes or “Discard” any changes. If a “Save” is done, all work done since the last save will be saved. If a discard is done to a previously unnamed project, nothing w

If a discard is done to an active database, all changes made since the last save will be discarded and Mesa Core will close with the last saved version of the database.TUTORIALS 41 LESSON #1Station & Shot LayoutThe first lesson is to have the user to become familiar with laying out a 3

17、-D seismic survey using MESA CORE 5.0. The exercise demonstrates a direct path through MESA without much diversion. The path will be laying out sources, receivers, defining a bin grid, shooting the survey, and calculating diagnostics. Within MESA different types of geometries can be created. Layout

18、types such as Diagonal, Zig-Zag, Mirrored Zig-Zag, Radial, Button, Random, etc can all be created. This exercise will focus on the Straight Line Orthogonal layout.點(diǎn)擊 Layout 下拉菜單,選擇 Stations,會(huì)彈出 Station Layout 菜單1)From the “Layout” pull down menu select “Stations”.
