【摘要】：腰英臺地區(qū)位于松遼盆地南部，長嶺斷陷中部凸起帶上。長嶺斷陷油氣資源豐富，勘探程度相對較低，油氣勘探潛力較大。本文綜合腰英臺地區(qū)及周邊臨區(qū)的巖心、測井及各項地質(zhì)基礎(chǔ)資料，運(yùn)用沉積學(xué)、層序地層學(xué)、古地理學(xué)等理論和方法，進(jìn)行研究區(qū)地層劃分、沉積相類型識別、相帶展布與砂體展布等方面的研究。通過本次研究，對腰英臺地區(qū)登婁庫組和泉一段的沉積特征有了更深入的認(rèn)識。 通過地震界面識別與追蹤閉合，采用旋回控制、巖性突變等方法，識別出登婁庫組二、三、四段和泉頭組一段的頂?shù)捉缑嫖恢茫⑷珔^(qū)目的層段的地層格架。 在對巖心宏觀和微觀特征描述的基礎(chǔ)上，通過分析其巖石學(xué)、沉積構(gòu)造和測井曲線特征，總結(jié)研究區(qū)的相標(biāo)志，最終識別和劃分出研究區(qū)的沉積相。 通過相標(biāo)志的識別，發(fā)現(xiàn)腰英臺地區(qū)登婁庫組和泉一段沉積相類型主要為辮狀河三角洲，伴有少量的湖泊相。辮狀河三角洲發(fā)育平原和前緣亞相，湖泊為淺湖亞相且分布較局限，主要在腰深2井登二段發(fā)育。 在對砂巖厚度圖、砂地比圖分析的基礎(chǔ)上，，結(jié)合全區(qū)構(gòu)造演化特征，確定登二、登三段物源來自南部，登四段物源主要來自西南部，泉一段物源主要來自東南方。最終確定了腰英臺地區(qū)登婁庫組和泉頭組一段的沉積相平面分布及垂向演化特征。
[Abstract]:Yaoyingtai area is located in the south of Songliao Basin, the middle uplift belt of Changling fault depression. Changling fault depression is rich in oil and gas resources, relatively low degree of exploration, oil and gas exploration potential. In this paper, the core, logging and geological basic data of Yaoyingtai area and its surrounding area are synthesised, and the stratigraphic division and type identification of sedimentary facies are carried out by using the theories and methods of sedimentology, sequence stratigraphy, paleogeography, etc. Study on the distribution of facies belt and sand body. Through this study, the sedimentary characteristics of Dengloku formation and Quan I member in Yaoyingtai area are further understood. By means of seismic interface identification and tracking closure, cycle control and lithologic abrupt change, the top and bottom interface positions of the second, third, fourth and first member of Denglouku formation and the first member of the Quantou formation are identified, and the stratigraphic framework of the target layer in the whole area is established. On the basis of describing the macroscopic and microscopic characteristics of the core, through analyzing the characteristics of petrology, sedimentary structure and logging curve, the facies marks of the study area are summarized, and the sedimentary facies of the study area are finally identified and divided. Based on the identification of facies markers, it is found that the sedimentary facies of Denglooku formation and Quanyi member in Yaoyingtai area are mainly braided river deltas with a few lacustrine facies. The braided river delta developed plain and front subfacies and the lake was shallow lacustrine subfacies and its distribution was limited. On the basis of the analysis of sandstone thickness map and sand ratio map, combined with the structural evolution characteristics of the whole area, it is determined that the source of Denger, Deng3, Deng4 and Quan are mainly from the south, the southwest and the southeast, respectively. Finally, the sedimentary facies plane distribution and vertical evolution characteristics of the first member of Denglooku formation and Quantou formation in Yaoyingtai area are determined.
