【摘要】：在根據(jù)前積反射結(jié)構(gòu)進行物源方向判別時,更多的是依靠觀察大量地震剖面進行的定性判別,沒有一套直觀、可操作的方法和流程。為此,借鑒構(gòu)造解釋中"玫瑰花"圖的制作原理,提出了判別前積體主物源方向的前積角"玫瑰花"圖,并歸納、總結(jié)了前積角"玫瑰花"圖的作圖思路和方法流程,包括前積體中心點的確定、正北基準(zhǔn)剖面前積角測量、與基準(zhǔn)剖面平行方位前積角測量、基準(zhǔn)方位前積角計算、旋轉(zhuǎn)基準(zhǔn)剖面求取其他方位前積角、成圖等6個步驟。利用前積角"玫瑰花"圖對渤海灣盆地BZ12構(gòu)造區(qū)前積體的主物源方向進行了分析,結(jié)果表明,前積體Ⅰ、Ⅱ的主物源方向分別為10°~20°、340°~350°,表明兩者源自不同的物源體系。
[Abstract]:In the discrimination of the source direction according to the front product reflection structure, more depends on the qualitative discrimination of a large number of seismic sections, and there is no set of intuitionistic and operable methods and processes. For this reason, drawing on the principle of making the "Rose" diagram in the structural interpretation, a "Rose" diagram of the front product angle of the main source direction of the former integror is proposed and summed up. This paper summarizes the drawing ideas and method flow of the "rose flower" map of the front product angle, including the determination of the center of the front product body, the measurement of the front product angle in the front of the benchmark section, the measurement of the front product angle in parallel with the reference section, the calculation of the front product angle of the base position, and the 6 steps of obtaining the other azimuth front product angles by the rotating datum profile, and using the "Rose" map of the front product angle. The main source direction of the precursor of the BZ12 tectonic zone in the Bohai Bay basin is analyzed. The results show that the main source direction of the precursor is 10 ~20 degrees and 340 degrees ~350 degrees respectively, indicating that both of the two are derived from different source systems.
