【摘要】：高臺子油田扶余油層形成于盆地穩(wěn)定沉降時期,以三角洲沉積為主。實施三維地震后,為充分利用新技術成果,更好地認識和精確地刻畫該區(qū)內扶余油層成藏特征,進一步挖掘其潛能,為此,對高臺子油田扶余油層的精細構造進行了研究。基于高分辨率層序地層學、沉積學理論指導,結合研究區(qū)內的測井、地震和錄井等資料對高臺子油田扶余油層的地層層序進行了綜合分析,將油層細分為2個長期旋回,6個中期旋回和17個短期旋回,建立了高分辨率層序地層格架。運用研究區(qū)的三維地震資料,結合鉆井、測井、井間地震資料,采用人工合成地震記錄、三維地震數(shù)據(jù)可視化、相似性分析、空間趨勢體分析、空間驗證-剖面識別、等時切片、縱向剖面比例放大、多屬性-多方法結合、趨勢面分析等一系列技術對研究區(qū)扶余油層進行了精細層位解釋、斷層解釋和微幅度構造解釋。結果表明:扶余油層整體構造格局為“南高北低、東高西低、中央隆起”。頂面整體呈現(xiàn)出一長軸近北東方向背斜,區(qū)內斷裂十分發(fā)育。規(guī)模較大斷裂主要分布于背斜軸部,走向北西向,背斜兩翼斷裂次之。受斷裂切割作用,背斜形態(tài)復雜化,呈現(xiàn)一系列的小背斜、斷階、地壘和地塹構造,并且有3個主要演化時期。結合已鉆井分析,研究區(qū)以斷背斜油藏、斷層-巖性油藏、反向斷階油藏為主。綜合構造研究成果及圈閉、儲層、沉積相、成藏等條件、鄰井生產情況等,確定了兩個有利油氣聚集的目標區(qū)塊。
[Abstract]:The Fuyu reservoir in Gaotaizi Oilfield was formed during the stable subsidence of the basin, mainly delta deposits. After the 3D earthquake, in order to fully utilize the new technical achievements, better understand and accurately depict the reservoir forming characteristics of Fuyu reservoir in this area, and further tap its potential, the fine structure of Fuyu reservoir in Gaotaizi Oilfield is studied. Based on the theory of high-resolution sequence stratigraphy and sedimentology, the stratigraphic sequence of Fuyu reservoir in Gaotaizi Oilfield is comprehensively analyzed by combining well logging, seismic and logging data in the study area. The reservoir is subdivided into 2 long term cycles, 6 intermediate cycles and 17 short term cycles, and a high resolution sequence stratigraphic framework is established. Using 3D seismic data of the study area, combining drilling, logging and cross-well seismic data, using synthetic seismic records, 3D seismic data visualization, similarity analysis, spatial trend volume analysis, spatial validation-profile recognition, A series of techniques, such as isochronous slice, proportional magnification of longitudinal section, combination of multi-attribute and multi-method, and trend surface analysis, have been used to interpret fine layer, fault and micro-amplitude structure of Fuyu oil layer in the study area. The results show that the overall structural pattern of Fuyu reservoir is "south high and north low, east high and west low, central uplift". The whole top plane presents a long axis near NE anticline, and the faults in the area are well developed. The large scale faults mainly distribute in the back inclined axis, strike NW direction, and the anticline two wing faults take the second place. The anticline is complicated by fracture cutting and presents a series of small anticlines fault terraces and graben structures and there are three main stages of evolution. Combined with drilling analysis, the study area is mainly faulted diagonal reservoir, fault-lithologic reservoir and reverse fault stage reservoir. By synthesizing the structural research results, traps, reservoirs, sedimentary facies, reservoir forming conditions and the production situation of adjacent wells, two target blocks favorable for oil and gas accumulation have been determined.
