董1井区静校正方法研究与应用

复杂地区静校正问题一直是影响资料品质的一个重要因素，为此，探讨了多种静校正联合应用的方法。董1井区地表条件复杂，为农田、碱地和沙漠混合区域。在资料采集时，布设的调查点根据地表实际情况而定，不拘泥于规则的排列形式，农田区采用较少的调查点，农田到沙漠区的过渡带加密调查点，沙漠区则采用微测井观测。静校正量的求取是采用模型约束技术并结合沙丘曲线获得的，并利用大炮近炮点排列的初至来分析控制高速界面。静校正处理后的剖面，形态真实，信噪比较高，并通过建立全区地表模型，获得了地表各层的厚度图和速度图。

Methodology research and application of seismic static data in Dong1 well area

It is more useful to solve static correction problems of complex surface by using various method of static correction. The field static is important in the all kinds of static correction. In the Dong1 exploration well area where is covered with cropland, alkaline land and desert. Then properly arranging inquisitional positions, collecting records of refraction survey and micro log, and introducing first breaks of record which has been static corrected. By using the technique that the models of surface structure control and combining data of dune curve experiment, all values of static correction are computed. After the static processed the section have form truly. And the S/N is high. Thickness map and velocity map from establishing surface modelling are obtained in all areas.
