| Kongnan area is located south of Huanghua basin. Huanghua basin is located in the southeast of Tianjin , next to Bohai Sea , north from the south of the Yanshan Fold Belt, east of Cangxian uplift, west of Chengning uplift, run to NE - SW, the distribution of the eastern Rift Valley into the Bohai Basin, thetotal area is 17000km2. The main sedimentary sequence is the third department. Superposition of multi-phase tectonic activity, fracture of great development, with complex structures .Extract the extraction of seismic as following: extract Profile attributes, physical attributes and layer attribute. In practice, layer attributes has the greatest significance.If extract the layer extraction, first of all, we need to divid the sequence for the 3D seismic data , then need to track the sequence, we need to pay attention on the fauh,onlap,downlap,truncation,toplap and avert those geologic detail interfere . Complete closure of the inspection sequence, the sequence need to be closed with GeoGraphix discovery interplolation 3D Autopick function , property calculation can run after the sequence was closed . we can calculate different properties with different time window . Generally speaking, under the premise that research purposes can be included in the required information , it's better to choice the smallest time window. By many times comparative and study, It's better to open the time window during 50ms to 150ms ,the purpose of the study to include the required information under the premise, to the extent possible, the choice of small time window. AvgEnergy . TotalEnergy and VarinAmplitude are good properties which can react the information of fault and deposit, it's better to consider and use those properties first when analysis with seismic properties .when regulating the Seismic attribute map , it's better to use the gradation colors, and need to remove the anomalous value .Take the bottom of sequence I as interface ,close the sequence , open the time window with 100ms , and make a calculation about the seismic attribute , by setting and optimizating the parameters , then can show the fracture's distribution in sequence I on the seismic attribute planar graph .Take the bottom of sequence II as interface ,close the sequence , open the time window with 100ms , and make a calculation about the seismic attribute , by setting and optimizating the parameters , then can show the fracture's distribution in sequence II on the seismic attribute planar graph .Take the bottom of sequence III as interface ,close the sequence , open the time window with 100ms , and make a calculation about the seismic attribute , by setting and optimizating the parameters , then can show the fracture's distribution in sequence III on the seismic attribute planar graph . After get the correlogram , base on the seismic profile , compare the fracture distrebution map in each sequence .Through the research of structure in the area to the assistance from seismic attribute, we found the accurate position and condition of the main faults in this area, main faults, there are Kongdong-Kongxi Fault Zone,Wumaying Fault Zone,Nanpi-Xuxi Fault Zone and so on .The results show that, The torsion of Wumaying caused by Xuxi Fault Zone , The formation of fracture system with Nanpi-Xuxi goose expression Fault Zone was also the same reason.Small fault system in slope zone, formed by the impact of concy and condom fracture.Sedimentation process of the fracture on both sides are by the control of the impact of of concy and condom. In particular, Sedimentation process of Nanpi-Xuxi depression are by the control of condom fracture. In addition. Crevasse fan delta deposits that from Nanpi-Xuxi inner depression was developed.Take the bottom of sequence I as interface ,close the sequence , open the time window with 100ms , and make a calculation about the seismic attribute , by setting and optimizating the parameters , then can show the range of different sedimentary phase's distribution and the change of sedimentary phase in sequence I .Take the bottom of sequence II as interface ,close the sequence , open the time window with 100ms , and make a calculation about the seismic attribute , by setting and optimizating the parameters , then can show the range of different sedimentary phase's distribution and the change of sedimentary phase in sequence II .Take the bottom of sequence III as interface ,close the sequence , open the time window with 100ms , and make a calculation about the seismic attribute , by setting and optimizating the parameters , then can show the range of different sedimentary phase's distribution and the change of sedimentary phase in sequence III . Then base on the seismic facies analysis and well date , analysis the change of sedimentary facies and the distribution range of sedimentary phase .According to the application of seismic facies analysis, seismic attribute analysis and the combination of well data, the results indicate that: In developmental Stages of Sequence 3, Braided-river delta,deltaic deposit and was mainly developed Shenvsi and Wumaying Area , fan delta deposits was developed in Nandi and Cangdong Area. Furthermore, deep and semi-deep lake facies in in Cangdong and Nanpi Depression, coastal shallow-lake precipitation facies was developed on Both sides of Kongdian Salient.Sedimentary Evolution was mainly exist in Nanpi-Xuxi II din mainly the types of Sedimentary Facies was delta facies, the Principal Provenance comes from Shenvsi and Wumaying.It has a wide range of infiltration about the sedimentary In developmental Stages of Sequence 3.Lacustrine Deposits was mainly developed , moreover deltaic deposit was developed with certain scale in Wumaying and Shenvsi Area. Meanwhile, different range will be shown according to the assistance from seismic attribute diagram, emphases area of exploration will be found, thus it can provide guidance to the Survey of oil and gas sesource.
