In this papcr, we make use of the orthogonal transformation method to transform the coefficient matrix of trcnd surface analysis to a diagonal matrix so as to avoid solving ill-conditioned system of cquations and improve the precision of solution . Meanwhile , the normal equations are transformed to a first-ordcr system of cquations which is very casy to solve,thcrefore, the solving process is sped up. Furthcr, the order-fixed trend surface analysis which is responsible for false anomaly is replaeed by sliding window and order-variant trend surface analysis. As a result, the application of the method in recognizing weak anomalies of high accuracy gravity survey and determining the accurate position of buried hill in oil-bearing sedimcntary basin has brought forth sat isfactory results.

本文引用正交变换法将趋势面分析中的系数矩阵化为对角阵,避免了求解病态方程组,提高了解的精度。同时正规方程组可变为十分容易求解的一次方程组,因而加快了求解速度。采用自动改变滑动窗口,改变趋势面阶数的办法,解决了因一次性选取固定趋势面而出现虚假异常的难题。将该方法应用于某含油气沉积盆地上高精度重力细测微弱异常的识别及古塔山精确位置的求取,取得了满意的效果。

Milankovitch cycles were discovered by FFT and Maximum Entropy spectraestimation within a sliding window along logging profile using right fliters, window length and steps. Wave length ratio and character of wave peaks and their relations were studied. Continuous and sharp changes were found and proved by lithologic analysis.

By adopting power spectrum method, the regional gravity and magnetic force data can be used to obtain the basement fluctuation and top, bottom interface depth of regional magnetic layer. The dependence of this method has generally direct relation with the size of sliding window and selection of fitting frequency section; horizontal size of geological body has less effect on calculation result, it is the top depth, thickness of geological body and the corrosponding degree of window with geological...

By adopting power spectrum method, the regional gravity and magnetic force data can be used to obtain the basement fluctuation and top, bottom interface depth of regional magnetic layer. The dependence of this method has generally direct relation with the size of sliding window and selection of fitting frequency section; horizontal size of geological body has less effect on calculation result, it is the top depth, thickness of geological body and the corrosponding degree of window with geological body that has the main effect.

利用区域重力、磁力资料采用功率谱法可以方便、快捷地得到一个新区或一个盆地的基底起伏、区域磁性层的顶底界面深度。区域磁性界面常常为磁性较强的火山岩顶底界面以及居里面,这对一个新区或一个盆地早期评价中的构造单元划分、资源量计算、区域地温场研究、有利远景区预测等具有重要的意义。应用功率谱法计算地质体顶底深度的可靠性往往与滑动窗口大小、拟合频段的选取有直接关系。研究表明,要计算埋深为h的地质体,窗口的大小应为(4~6)h,拟合频段根据模型实验确定;地质体水平尺寸对计算结果影响不大,起主要影响的是地质体的上顶埋深、地质体的厚度及窗口与地质体的对应程度。
