Around the Tarim Basin, the eastern part of exploration over many years, our predecessors have done different levels of sub-regional research for different purposes in this interval, the area of ??the Upper Ordovician target layer deep drilling reveals, the zone structure, deposition, and reservoir characteristics of the low level of awareness. In this paper, seismic wave field of multi-parameter information, combined with the Tower East Upper Ordovician results of previous work and drilling, logging data, under the guidance of the basic theory of sequence stratigraphy, sedimentology, structural geology and petroleum geology for the area in the Upper Ordovician clastic strata to carry out a comprehensive evaluation of the reservoir. Mainly done the following and achieved rich results. 1) on the part of the block target layer resolution, lower signal-to-noise ratio of two-dimensional seismic data, the post-stack data processing (199L, 14908km) through the application of wavelet shaping deconvolution, blue filter and a combination of de-noising processing method to improve data quality; 2) analysis of 14 well logging data, accurate calibration of the target layer bit frequency seismic attribute divided sedimentary cycles (11L, a total of 110), combined with outcrop - logging data, sequence stratigraphic framework, the purpose of the layer is divided into a class II sequences and four grade III sequence; 3) the fine structural interpretation (326L, 23630km) in the borehole calibration and correction, based on the velocity spectrum, with varying velocity mapping the average velocity and the velocity field (252L, 18198 PUDIAN, 235,960 TV on), through the analysis of structural and stratigraphic thickness of the overall area was around the long concave tectonic pattern formation thickness and geological environment; 4) the combination of conventional and modern way seismic facies analysis (185L, 2T), technical analysis of leveled layer 4 during the deposition before palaeogeomorphology ( 326L, long profile), a single well sedimentary facies analysis of the three layers of sedimentary facies that the performance of the layers fan bodies, Delta, marine three categories, during the deposition of inheritance. 5) based on the acoustic impedance inversion of seismic data, through the borehole relationship between constraints and a mathematical model, inversion of the destination layer wave impedance, porosity, permeability, clay content, percentage of sandstone, sandstone thickness reservoir physical parameters (326L), a comprehensive analysis of the reservoir characteristics, the development of the reservoir three rating criteria to predict the layers favorable area in Longkou anticline with many proposed exploration targets. Multiple seismic attributes in reservoir prediction method in the application of the area, pointed out the direction for the next step in oil and gas exploration in the area.
