摘要
本文在系统研究库车坳陷东部下-中侏罗统砂岩储层中流体包裹体的基础上,探讨了研究区下-中侏罗统油气充注期次及其流体包裹体在构造变形中的指示意义。
     库车坳陷东部下-中侏罗统砂岩储层中发育丰富的液烃包裹体。对与液烃包裹体共生的含烃盐水包裹体特征和显微测温数据的系统分析表明,该地区自中新世中-晚期以来油气持续充注,并存在两期主要的充注过程。第1期发生在早成岩阶段晚期,为低成熟油气充注,充注时间为12-10Ma(大致相当于中新世吉迪克期);第2期发生在中成岩阶段早期,充注时间为9-7Ma(大致相当于中新世康村期),主要为低成熟油气充注,并伴有少量发浅黄色荧光的成熟油气充注。不同层位包裹体的丰度有明显差别,下侏罗统阿合组(J1a)和阳霞组(J1y)包裹体丰度(GOI)明显比中侏罗统克孜勒努尔组(J2k)和恰克马克组(J2q)高,这可能与砂岩的粒度有关,下侏罗统砂岩粒度较大,发育比较优质的储层,有利于包裹体发育:中侏罗统砂岩粒度较细,储层物性较差,不利于包裹体发育。
     通过对流体包裹体面(FIP)的简单研究,发现本次采集的岩石样品中流体包裹体面(FIP)存在一个以上的优势定向方位,推测研究区可能经历了至少两期不同方位区域应力场的构造变形。
     根据对库车坳陷东部下-中侏罗统砂岩中流体包裹体特征及均一温度数,推测研究区分别在吉迪克期和康村期经历了两次较强烈的构造变形,这与其它地质证据获得的认识基本一致。此外,在不同变形程度剖面上采集的样品具有类似的流体包裹体特征,说明研究区的构造变形对流体包裹体的改造作用较弱,流体包裹体在形成之后基本上处于稳定状态。
This paper studied the formation time of oil reservoirs and the instruction meaning in structural transfiguration of lower-middle Jurassic in eastern Kuqa depression based on systematic researches on the characteristics of fluid inclusion of lower-middle Jurassic in eastern Kuqa depression.
     The lower-middle Jurassic Sandstone reservoir develops hydrocarbon-rich fluid inclusions in eastern Kuqa depression. It shows hydrocarbon charging order twice oil and gas injection there, which analyzed by saltwater inclusion symbiotic characteristics with hydrocarbon inclusions and microscopic measurement data. The first one occurred in the late stage of early diagenesis, approximately 12~10Ma(Jidike period in Miocene), it mainly charged to low mature oil and gas; the second one happened in the early stage of middle diagenesi, approximately 9~7Ma (Kangcun period in Miocene), charged by low mature oil-gas with small amount of light yellow fluorescent mature oil and gas. Disparate layers have GOI in difference obviously, the GOI in Lower Jurassic Ahe group (J1a) and Yang Xia group (J1y)is much higher than that in Jurassic Cakmak group (J2q) and Kezilenuer group (J2k), which is relevant to the physical characteristics of reservoir. The lower Jurassic bed is in favor of development of fluid inclusions with better physical property reservoir, in contrast, the worse physical property in middle Jurassic with smaller grain size, which is not conducive to develop for fluid inclusions.
     According to study Fluid Inclusion Planes(FIP) simply, there is more one advantage targeting position of the Fluid Inclusion Planes (FIP), speculated that the study area may have experienced at least two different directions of regional stress field deformation.
     According to the characteristics and homogenization temperatures of fluid inclusions of lower-middle Jurassic in eastern Kuqa depression, suggested the study area experienced two strong tectonic deformation, it's consistent with the other geological evidence. There is similar charateristics of fluid inclusions which collected on the different deformation profiles,this result sures that the structural transfigurat on the fluid inclusion is weak, the fluid inclusions are basically in a stable condition after formation.
