【摘要】 综合采用沉积学、石油地质学、构造地质学、油藏工程、测井地质学、储层地质学的理论与分析方法，从储层的成因模式入手，综合利用测井、地质录井、岩心分析、钻井、生产以及试油、试采及各项分析化验等方面的资料，对研究区高台子油层区域地质概况、储层特征、沉积特征、油气藏特征及成藏机理、构造特征、油层潜力、油气水分布规律等方面的内容进行深入研究，成果对于红岗油田的进一步油气的勘探和开发具有很大的指导意义。 红岗油田位于吉林省西部大安市两家子乡境内，构造上位于松辽盆地南部中央坳陷区红岗阶地南端的红岗构造上。通过研究大量测井、录井及岩心资料，依据“旋回对比，分级控制”的原则，在标志层的控制下，将高台子油层划分为三个油层组、10个砂层组、40个小层、56个沉积单元。通过对目的层岩性、沉积构造、古生物、沉积序列、岩石组合及测井曲线特征的研究，认为高台子油层属于辫状河三角洲相沉积，研究层段主发育三角洲前缘—前三角洲亚相，发育的微相类型有水下分流河道微相、分流河道间微相、河口坝微相、河口坝缘微相、坝缘席状砂微相、河口坝坝间微相、远砂坝微相、前缘席状砂微相、前三角洲微相、滑塌与浊流微相。对本区182口井进行了单井相、联井相分析以及平面相组合，并在此基础上对三个油层组进行沉积演化分析，总结出本区的沉积相模式。从平面相展布、砂体形态及渗透率计算结果知本区储层非均质性较为严重。 据构造、储集层和流体分布等资料研究表明，高台子油层主要发育构造层状油气藏和层状构造岩性油气藏两种油气藏类型，通过对油气运移方向、砂体圈闭效应及油气供给方式与数量的分析总结出目的层的四种成藏模式：薄层高圈闭模式、厚层构造—岩性圈闭模式、向高点迁移模式和优选通道模式。高台子油层油气水的分布关系复杂，厚砂层以含水和高含水同层为主，薄层含油性相对较好。 综合沉积相、砂体、地层结构和油气水分布规律，以及目前油层动用情况分析，认为20层、10+11层、13+14层、18层、23层、27层、28层、29层、33层、39层应是本区高台子的主力潜力层。更多还原

【Abstract】 Based on the theories and methods of sedimentology, petroleum geolgoy, architectonic geology, petroleum reservoir engineering, well logging geolgy and reservoir geology, starting from the study of reservoir genetic model and synthetically using the data of well logging, mud logging, core analysis, well drilling, oil production test and other analysis method, this article deeply studies the regional geological background, character of resvervoir, character of sedimentation, character of gas and oil pool and the oil forming mechanism, structural character, potential of oil layer, the distributing character of oil, gas and water. The results deeply influence the further exploration and exploitation of Honggang Oil Field.Honggang Oil Field locates in Liangjiazi township, Daan city ,Jilin province. It is in the Honggang structure ,which is in the southern part of Honggang terrace of central depression in Songliao Basin. By the analysis of abundant data from well logging, mud logging and core , under the principle "comparison acceding to cycle, control by hierarchy", this work divides the Gaotaizi Oil Layer into 3 oil layer groups, 10 sandstone layer groups, 40 mbrs and 56 sedimentary units under the control of standard layers. Via the anaylysis of lithology, sendimentary structure, paleontologic fossils, sedimentary succession, rock association and curve character of logging of objective layer, Gaotaizi Oil Layer belongs to braided stream delta facies, the objective layer mainly develops delta front-predelta intrafaeies, and the main microfacies are subaqueous braided distributary channel microfacies;river mouth bar microfacies; subaqueous braided interdistributary channel microfacies; distal bar microfacies;delta front sheet sand microfacies , and so on. After facies analysis of single well and multi-well and combination of in-plane facies of 182 wells in this region, this work analyses sedimentary evolvement of these 3 oil layers and generalizes the sedimentary model of this area. From the distribution of in-plane facies and the shape of sandstone and the permeability of the reservoir, the reservoir heterogenity in this area is distinct.The data of strucure, reservoir and distribution of liquid show that Gaotaizi Oil Layer mainly develops structural stratified oil and gas pool and stratified-structural-lithological oil-gas pool. After anaylysing the direction of oil and gas migration, the sand trap effect, the mode and quantity of the oil or gas supply, four oil forming mechanism models are concluded: thin layer high trap model, thick layer structural -lithological trap model, migration to higher point model and optimized pathway model. The distribution of water-oil in Gaotaizi Oil Layer is very complex, thick sand layer usually contain only water and thin layer contain more oil.Synthesizing the sedimentary facies, sand body and water-oil-gas distribution law and the oil layer employment anaylysis, thembrsof20, 10+11, 13 + 14, 18, 23, 27, 28, 29, 33, 39 are the main potential oil mbrs of Gaotaizi Oil Layer in this area.更多还原
