中文摘要：

在复杂过渡带三维地震勘探项目中,施工设计包括海陆观测系统设计、从属线束设计、偏点设计等,其优化对于提高地震数据采集效率,保证资料品质,减少空炮、废炮和重炮,实现资料无缝连接至关重要。这就要求技术人员针对工区特点提前合理设计特殊观测系统,优化炮点布设,从而最大限度地满足覆盖次数均匀的需要。通过自动优化设计施工方式,可以减少人工误差,使采集结果最大限度地实现设计要求,从而提高效率、节约成本。

英文摘要：

The conventional transition zone in three-dimensional（3D）operational design is made by splitting the operational area into two parts（land and ocean）in accordance with the basic parameters of the contract after scouting the practical water depth,obstacles,and terrain.Then the acquisition can be made according to two kinds of geometry.of course,the kinds of sources are different due to water depth and land terrains;there are different guns,explosives,and vibroseis.During the period of design,the design of offset points is finished by using professional software,such as green mountain or KLseis.When acquisition is completed,the offset point＇s optimization is made.There are three problems in the actual operation.Firstly,the progress of the project is limited to permit progress,and permits are very difficult to get in some places,which affect the production schedule.Secondly,the design period is longer due to the conventional design methods.Thirdly,for the complex region,the late offset point optimization makes it very difficult to meet the requirements of the original design,which results in void or invalid shots and affects the economic benefits.Because of these problems,it is urgent to find a method to make design flexible and fast.This design can reduce the design period,improve the design efficiency,and meet the requirement of uniform fold to the maximum extent in the process of optimization design.It is even more important in complex transition zone 3Dseismic exploration projects.Our operational designs include ocean geometry,land geometry,sub-swath,and offset point designs.It is vital for the optimization of the operation design method to improve the seismic data acquisition efficiency,ensure the data quality,reduce duplication of shooting,and realize a seamless connection of the data.This requires that the technician designs special micro-geometry and optimizes shot layout in view of project characteristics to meet the needs of maximum uniform fold.This paper presents an automatic optimization design
