摘要: 通过矿物成分分析、砂地比计算、地震属性分析及测井响应特征识别等技术手段,对塔里木盆地哈拉哈塘—哈得地区中生界典型沉积时期的古地貌形态、沉积体系展布、地层及砂体发育特征等进行了研究。研究结果表明:①塔里木盆地哈拉哈塘—哈得地区三叠系物源主要来自东北部的天山造山带,其ZTR系数由东北部向凹陷中央逐渐增大;侏罗系和白垩系物源主要来自东南部和南部的昆仑山造山带,其ZTR系数由北部、南部向凹陷中央逐渐增大。②三叠纪晚期,随着古特提斯洋的增生,研究区北部天山的隆升强度减弱与南部昆仑山的隆升强度增大是此次物源转换的主要原因。③三叠纪,研究区的沉降-沉积中心位于南部,主要发育了一套北东—南西向的辫状河三角洲—深水湖泊沉积;侏罗纪和白垩纪,沉降-沉积中心则跃迁到研究区北部,主要发育了一套南东—北西向和南—北向的辫状河三角洲—浅水湖泊沉积。④三叠纪,砂体叠置样式的前积方向主要为北东—南西方向;侏罗纪和白垩纪,砂体叠置样式的前积方向主要为南东—北西方向和南—北方向。⑤三叠系岩性油气藏主要发育于研究区西南部,侏罗系和白垩系岩性油气藏主要发育于研究区西北部和北部。

Abstract: The sediment supply and infilling evolution of the Mesozoic in Halahatang-Hade area of Tarim Basin were studied by analyzing the changes in paleogeomorphic morphology,distribution of sedimentary systems, stratigraphic structure and sand-bodies development characteristics,based on the main measuring method of mineral composition analysis,calculation of sand to land ratio,seismic attribute analysis and logging response feature recognition. The results show that:(1)The provenance of the Triassic mainly came from the Tianshan orogenic belt in the northeast,with ZTR coefficient gradually increasing from the northern area to the central sag. During the Jurassic and Cretaceous,the provenance mainly came from the orogenic belt of Kunlun Mountains in the southeast and south. The ZTR coefficient of this period is gradually increasing from the northern and southern areas to the central sag.(2)In the late Triassic,with the proliferation of the Paleo-Tethys Ocean,the weakening of the uplift of the Tianshan Mountains in the north of the study area and the intensification of the uplift of the Kunlun Mountains in the south are the main reasons for this provenance transformation.(3)During the Triassic,the depression and deposition centers were located in the south of the study area,and a set of braided river delta and deep-water lake deposits in the NE-SW direction were mainly developed. During the Jurassic and Cretaceous,the depression and deposition centers migrated to the north of the study area,and a set of braided river delta and shallow lake deposits were developed in the direction of SE-NW and S-N respectively.(4)During the Triassic,the progradation direction of sand-bodies was mainly in the NE-SW direction. During the Jurassic and Cretaceous,the progradation direction of sand-bodies was mainly in the SE-NW and S-N direction respectively.(5)The exploration areas for Triassic lithologic reservoirs are located in the southwest of the study area,while the exploration areas for Jurassic and Cretaceous lithologic reservoirs are located in the northwest and north of the study area.

Key words: provenance transformation, sedimentary filling-stacking pattern, seismic attribute, ZTR coefficient of heavy mineral, intensity of uplift, lithologic reservoirs, Mesozoic, Halahatang-Hade area, Tarim Basin
