2. tazhong ancient uplift originated from normal fault in paleozoic, hydrocarbon formed in ordovician period, structure reverse made tazhong uplift form from the middle ordovician period to the late ordovician period, and it provided geologic background for the deposit of silurian - devonian stratum. tazhong uplift formed at the end devonian, ancient reservoir was destroyed and asphaltum sandstone formed, structure deformation more destroyed ancient reservoir in early permian, after then the major of structure deformation is regulation
塔中隆起源於早古生代拉張背景下的正斷層，寒武-奧陶紀為其烴源巖形成的重要時期；早奧陶世末-晚奧陶世末的構造反轉是塔中隆起的主要形成期，同時也為志留系形成地層及復合圈閉提供了古地理背景；志留?泥盆紀塔里木盆地南北緣均轉為活動大陸邊緣，形成了大量的斷裂和不整合；泥盆紀末塔中鼻狀隆起基本定型，古油藏遭受破壞，形成了瀝青砂巖；早二疊世晚期的構造變形使古油藏遭受進一步的破壞；二疊紀后構造變動主要以調節為主。 -
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。 -
Was made up of thick neutral and basic volcanics, volcanoclastic rocks and few normal sedimentary rocks. the sedimentary rocks of tiaohu fm. were mainly composed of terreverte or mauve mudstone, sandstone and glutenite
條湖組的分佈范圍與蘆草溝組大致相當，但巖性卻差異很大，為厚層中?基性火山巖、火山碎屑巖，是火山活動頻繁的證據，條湖組沉積巖夾在火山巖中間，主要為灰綠、紫紅色泥巖、砂巖及砂礫巖。
