Firstly, the volcanics and shaly sand were separated with FMI static images and conventional logging data. Then, the image characteristics of all typical volcanics were analyzed with the dynamic FMI images to establish the FMI image patterns of volcanic lava (including rhyolite, dacite, andesite, and basalt) and volcaniclastic rock (including volcanic breeds and tuff).
首先利用FMI静态图像和常规测井曲线将砂泥岩与火山岩区分开来;然后利用FMI动态图像分析了火山岩各种岩性的图像特征,归纳总结出火山熔岩类(流纹岩、英安岩、安山岩、玄武岩)和火山碎屑岩类的FMI图像模式。

Sedimentary facies model for mixed sediments of recent reefoid carbonates and siliciclastics is developed from the facies model of fringing and barrier reefs. Based on the sedimentary facies and textures, mixed sediments may be subdivided into 5 types as follows: 1 reef base mixed sedimentary rocks and reef framework mixed sedimentary rocks; 2 reef flat sand-gravel mixed sedimentary rocks; 3 backreef beach-dune gravel-sand mixed sediments; 4 backreef lagoonal sand mixed sediments ; and 5 reef front littoral sand mixed sediments.
礁源与陆源混合沉积相模式是从岸礁一堡礁相模式基础上发展而来,根据其沉积相和沉积结构特徵可以分为5种混合沉积:①礁基混积岩和礁格架混积岩;②礁坪砂砾屑混积岩;③礁后海滩-沙提砾砂屑混合沉积;④礁后泻湖砂屑混合沉积;⑤礁前浅海砂屑混合沉积。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1~N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

The main lithologic characteristic is that the rock types are dominated by light-colored clastic rocks reflecting the oxidation environment with a low maturity. The grain size distribution and sedimentary structure show that the rocks have the sedimentary characters of both gravity currents and tractional currents. Plant fragments are lacking and bioturbation structures are abundant and cyclic. Sandbodies are distributed in a ring shape.
其主要岩性特征为:岩石类型以反映氧化环境的浅色碎屑岩类为主,成熟度较低,粒度分布和沉积构造反映其兼有重力流和牵引流的沉积特点,植物碎屑贫乏而生物扰动构造丰富且具周期性,砂体呈环带状分布。

According to the analysis of features of the key outcrop sequence stratigraphy, build the sequence frame, through the section comparison, and the study of feature of the 5 key outcrops, then it can be concluded that, conglomerate on the denudation plane or the other contrastive sediment are the main features surrounding the bottom border of the sequence. In the foreland basin sediment environment, the transilient group of mud rock and sandstone are the main sediment features of low-stand system tract. Thick mud rock and sandstone interbedded is the chief component of transgressive system tract, sometimes together with thick turbidity current sandstone; High-stand system tract is composed by the combination of mud rock and sandstone interbedded, with the progradation as its main style. Maximum flooding surface Sediment are usually mudstone, and the thickness is different from each other.

The fold cambers in plane which protrudes to the south. Regional tectonic pattern show bigger hiberarchy, which mainly is composed of roof -slippage-fault-fold. The tectonic pattern of shallow hiberarchy which includes middle-upper Triassic's fragmentary rock is fault-propagation and low-angle faults fracture, its roof rock is mainly pelyte. The tectonic pattern of midding-deep hiberarchy which includes upper Paleozoic's carbonatite is possibly thrust and broad-tempered fold.
研究区的构造样式表现出较大的层次性,总体为盖层滑脱式逆冲褶皱型,其中,以中、上三叠统碎屑岩为主的浅层次,其构造样式主要为紧密型断滑或断展褶皱低角度逆冲断裂,其滑脱面为三叠系下部泥质岩或粉砂质泥岩;以上古生界碳酸岩为主的中深层次,其构造样式推测以冲断和宽缓褶皱为主。
