摘要
本文根据研究区的地质特征,充分利用取芯井资料和测井资料以及油田静态数据库,对大庆萨尔图油田萨北开发区北二西部SⅡ、SⅢ两套二类油层组的储层非均质性、剩余油的分布进行了研究。
     研究区二类油层小层有效厚度和渗透率比较低,分布零敞,变化比较大,非均质性很严重;受沉积相控制,二者之间有明显的对应关系,一般情况卜,高的有效厚度带往往具有较高的渗透率。多相带组合、高频率的多旋回沉积构成了北二西严重的层间非均质性。小薄层广泛发育,SⅡ、SⅢ分层系数较大,各层间的渗透率非均质程度差异很大。并且层间隔层分布广、厚度大,构造裂缝北西方向延伸,使层间非均质性程度更加剧烈,平面非均质性受沉积相带控制,双重渗透率方向性严重。
     按其成因将剩余油归纳为井网控制不住型、渗透能力差型、滞留区型和隔层损失等四种类型,从研究结果来看,调整区剩余油主要是注采不完善型、渗透能力差型,其次是滞流区型和隔层损失型。
     通过研究分析,北二西二类油层剩余油具有以下特点:
     (1)剩余油以表内薄差层和表外层为主,渗透能力低;
     (2)剩余油比较零散;
     从纵向上看,调整区剩余油存在萨、葡、高各个油层组内,分布在300—400m的井段上,100—160个小层内,可见剩余油在纵向上十分分散。
     从平面上看,剩余油分布面积比较小,相当零散。
     (3)剩余油与水淹层和水淹带的接触相当复杂,具有复杂性;
     调整区剩余油从纵向上看,剩余油层与见水层相间分布,隔层小;从平面上看,由于油层平面的非均质性,相对较好部位已水淹,只在油层的边边角角部位由于注采不完善等因素存在剩余油,剩余油被水淹带包围,所以目前剩余油与水淹层利水淹带的接触相当复杂,这对完井方式的选择提出更高的要求。
This dissertation describes a detailed study of the reservoir heterogeneity and remaining oil distribution of SII, SIII, the better oil layers, in the North-II-West Tract of North Saertu oil field in Daqing. This study is based on the geologic characteristics of the research area, fully utilizing core hole data and log data, oilfield static database.
    In research area, the widely varying substrata has the thin effective thickness, low permeability, scattered distribution and obvious heterogeneity .Controlled by sedimentary facies, it has obviously corresponding relationship with the sedimentary facies. For this reason, substrata with thick effective thickness have better permeability. Multiple sedimentary facies association and high-fequency polycycle sedimentation lead to serious
    interlayer heterogeneity of this area. With laminae and big hierarchical coefficient of S1I, SI1 , permeability heterogeneity differs vastly between substruta. Widely dispersed, thick barrier layers and west-north-ward structural fracture strengthen the interlayer heterogeneity; Plane heterogeneity is in control of sedimentary facies belt, which leads to the directivity of double permeability.
    According to contributing factors, the remaining oil can be divided into four types(type-I-out of well pattern control ; type-II-with bad permeability; type-Ill-in remained oil area; type-IV-in barrier bed). While according to the study results, remaining oil in adjusting area mainly consists of injection-production faultiness type, low permeability type and stagnant area type as well as barrier bed type.
    The analysis result shows that the remaining oil of this area is characterized as:
    1. Remaining oil is mainly distributed in thin tabulated beds and untabuiated beds with low permeability.
    2. Remaining oil scatters widely.
    Vertically, in adjusting area remaining oil mainly exists in Sa, Pu, Gao oil reservoir groups, 300-400m well section, between 100-160 substrata; Horizontally, remaining oil disperses in small area.
    3. Complexity exists in the contact between remaining oil and water flooded layers and zones. Vertically, the remaining oil layers in adjusting area alternates with water breakthrough layers, between them the barrier beds is thin. Horizontally, because of the plane heterogeneity, the relatively good intervals are flooded, so that the remaining oil only exists in margin oil layer owing to faultiness of injection-production; remaining oil is enclosed by waterflooded zone, therefore, it is so complex relationships between remaining oil and waterflooded layers and zones that high requirements are made in the choice of completion optimization.
