Abstract:
Linearization processing is somehow to turn black and white isopic axis into a line where the positive axis indicated by a solid line while the negative axis shown by a dotted line. After the linearization processing, geological information in the available two dimensional or three dimensional geological profile will be more highlighted and reflect it more clear for what it is. Take Yingcheng Formation within Anda fault depression in Songliao basin for example, a corresponding relation between seismic phase and sedimentary facies has been established by analyzing single well facies of Dashen No.1 well and through sedimentary microfacies division.It is believed by interpreting sedimentary facies after the linearization processing for through wells and non-through wells in the region that in the period of Yingchen Formation the volcanic activity was strong and overflow facies was a dominant one developed by swamp facies, braided stream facies and semi-deep lacustrine facies etc. The extension of the sedimentary facies belt is just like a ringlike belt divided into two S-N fault depressed lakes by the uplift, small Anda area in the north is mainly composed of flood plains with volcanic rocks in the middle and Mingshui slope and hills around are believed to be material source areas; Small Songzhan area in the south trend to E-W direction with the volcanic rock uplift at the center, and with two semi-deep lacustrine deposit centers and uplift zones around are material source areas.
Key words: Linearization, seismic profile, Anda fault depression, seismic phase, sedimentary facies application
