2, by detailed studying of sedimentary microfacies, guan 3 - 6 beds mainly belong to high crooked fluvial deposition system, and some parts of guan 5 - 6 show plait fluvial deposition system features : detailed divided them into edge beach, center beach and natural levee etc. 9 deposition microfacies and beach ridge and groove microficies
2 、通過沉積微相多層次逐級細分研究，認為館3 - 6
砂層組主要屬于高彎曲度曲流河沉積體系，館5 6部分小層表現為辮狀河沉積體系；並細分出了邊灘、
心灘以及天然堤等九種沉積微相，以及灘脊和凹槽等微微相。
Based on 3 - d seismic well and logging data, mainly by means of advanced seismic theories of reservoirs prediction and other corelational multidisciplinary, an extensive and indepth studying on the tight sandstone reservoir with fracture of the second part of the xujiahe formation in west sichuan depression has been carried out. a series of theoretical viewpoints and research fruition are concluded as follows :. 1 on the basis of analysis of the regional and local structure characteristics and evolution, a conclusion comes in to being : inchoate and nowadays structure traps and the match model between structure and fracturation system are the main factors in controlling the formation of effective traps
本文綜合利用三維地震、鉆井、巖
心、測井資料，採用地震儲層預測方法為主線的多學科綜合研究思路對川西坳陷上三疊統須家河組二段緻密裂縫性
砂巖儲層進行了較為廣泛、深入的研究和探索，取得以下一系列理論認識和研究成果： 1 、通過區域及局部構造特徵及構造演化史分析，認為古今構造圈閉、構造與斷裂系統配置關系是控制有效圈閉形成的主要因素。
Through studying it is shown that in chagan sag, the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion, lithology and underground water behaviour ; there are three types of mudstone compaction, i. e. normal compaction, undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs, i. e. normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity, hydrocarbon generation, widening on oil and gas exploration domain and selecting exploration targets, etc
研究表明，查干凹陷中
心的地溫梯度高於凹陷邊緣，大地構造性質及所處構造部位、巖性與地下水活動的差異是影響凹陷地溫場分佈特徵的主要因素；泥巖壓實存在正常壓實、欠壓實和過壓實三種類型，
砂巖儲層段壓力類型可分為正常和負壓兩個系統，地層抬升剝蝕是導致儲層負壓系統形成的主導因素；凹陷獨特的溫壓場特徵對烴源巖成熟、油氣生成、油氣勘探領域的擴大及勘探方向的選擇等具有重要的油氣地質意義。
