Seismic Data Interpretation And Structural Analysis In13Rooms Area

13Rooms area， which is one of lower level of exploration blocks inTurpan-Hami basin，remains many basic geological problems to be resolved．Theresearch purpose of this thesis is to find out structure types，tectonic style，tectonicdeformation，tectonic evolution characteristics in the researched region．So as to pointout the favorable exploration regions and local structure，laying the foundation forfurther hydrocarbon exploration．Based on the petroleum geology，structural geology，geophysical prospectingtheory，combined with regional geological data，drilling and logging data，magneticdata and outcrop data，focusing on fine interpretation of seismic data，the division oftectonic style，the analysis of the tectonic deformation characteristics in the researchedregion．On the basis of making full use of all kinds of information，the seismicinterpretation model is established．with the guidance of the model，the structuralinterpretation of all seismic surveys are compled．A few structural maps are Compiledincluding Triassic bottom， Badaowan formation bottom， Qiketai formationbottom．The fracture distribution and structure type of each layer are figuredout．Tectonic styles of the three tectonic units including northern piedmont zone，slope zone in taibei sag，liaodun uplift are divided and the distribution regularity oftectonic style is summarized．For Fang1well anticline and QiKeTai structure hascarried on the detailed anatomy，made clear its formation mechanism，formation timeand tectonic formation，and summarizes the model of structure formation in theresearched region． Results show that：(1)There are two types of fault: basement rift and superficialfault，which including tear faults，basement-involved faults and cover-decollementpattern faults．Besides a variety of other types of anticline can be seen，such assqueezed anticline，dragged anticline，shear anticline，decollement fold，drapinganticline．(2)The growth strata shows that fang1well anticline developed withdepositionof Qiketai formation and Qigu formation．while the growth strata of Qiketaistructure is only Qigu formation．Deformation mode of Growth strata presents trianglewedge and inclined fan，which reveals forming mechanism of the Fang1well anticlineowing to the combined effect of Limb rotation and kink-band migration．(3)It is putforward that slip factor plays the leading role in the process of structure formation ofQiketai structure and Fang1well anticline．Three stages slip-mode is established，which reveals that anticlines were forming in the first and second stages，butanticlines were destroyed in third stage．(4) The northern piedmont formation mainlydevelops all kinds of basement-involved thick-skinned structure．strong stratumdeformation are due to compressional stress from north to south by bogurda mountainuplifting．Taibei sag mainly develops thin-skinned structure; tectonic style in Liaodunuplift is relatively single，mainly made up by basement faults， only ramp thruststructural styles，suprasalt pop-up and healed structure．...
