Directed by the advance theories of sequence stratigraphy , reservoir beds sedimentology , seismic stratigraphy and petro - geology , measured by exactitude seismic procession , analysis of seismic facies , analysis of single well lithfacies and sedimentary facies , study of macro and micro character of reservoir and diagenesis , this paper study comprehensively the stratigraphy sequence , the type and distributiong of sedimentary facies , reservoir properties , the diagenesis and the evolution of pores of the 2nd and 3rd parts of pingdiquan formation of permian in wucaiwan - shishugou region in jungan basin . we can optimum seek favourable target area and apply the study results on oil field production in order to solve the difficult questions . we mainly achieve several views as follows : l ) establish the sedimential sequence framework of permian formation in studying area and delimint the jiangjunmiao formation of middle dyas series as lowstand system tract , the lower of the second part to the third part of pingdiquan formation of middle dyas series as transgressive system tract , the upper of the second part to the first part of pingdiquan formation as highstand system tract 以层序地层学、储层沉积学、地震地层学、石油地质学的先进理论为指导，以地震资料精细目标处理、地震相分析、单井岩相分析、沉积相分析、宏观和微观储层特征分析及成岩作用研究为手段，对准噶尔盆地东部五彩湾? ?石树沟地区二叠系平地泉组二、三段的地层层序、沉积相类型及展布、储层物性特征、成岩作用及孔隙演化进行综合研究，优选出有利勘探区带，并将研究结果应用到生产中，解决生产中的难题，主要取得了以下几点认识：建立了工区内二叠系沉积层序框架，把中二叠统将军庙组地层划为低水位体系域，中二叠统平地泉组二段下部三段地层为水进体系域，二段上部一段地层为高水位体系域。
The development of sedimentary environment of yanchang formation be analyzed and discussed further . based on the analyses of all kinds of sedimentary deposit . under the direction of the theory and methods of sequence stratigraphy , 4 type i sequence boundary could be recognized in the study area , according to the marked bed including plane of deflation , scour , the plane of lithological salutation , structural transformation , down cutting channel sheet sand and so on . type i sequence consists of low stand systems tract , transgressive systems tract and high stand systems tract 本文采用当代层序地层学理论和方法，利用风化剥蚀、冲刷面、岩性岩相突变、结构转换面、构造机制转换面等层序界面的识别标志，将研究区延长组划分为四个层序，其层序界面都为型层序界面，具有三元体系域结构特征，由低水位体系域、水进体系域和高水位体系域三个部分组成。
A water power generating facility makes use of the energy difference between two different levels of flowing water by transferring the water from natural bed of the stream at the higher level to the bed at the lower level and effectively extracting its potential energy , which is then made available at the rotor shaft for further use 通过利用河流中不同水位之间的能量来驱动螺旋泵的转轴，在将高水位的水流输送到低水位的过程中汲取水流中储存的能量，将其转化成电能。
