【摘要】：本文以構造地質學、油區(qū)構造解析、沉積學、地震勘探原理和石油地質學理論體系為指導,在前人研究的基礎上,利用地震、測井、鉆井、錄井和生產動態(tài)資料,通過井震結合和動靜結合,采用切片技術、相干體技術、螞蟻追蹤技術和三維可視化技術等多種技術手段,進行構造精細解釋,在幾何學、運動學和動力學方面進行構造特征研究,利用定性分析和定量預測相結合完成儲層預測。濱南油田濱8塊整體表現為西部凹槽、中部隆起、東部斜坡的構造格局。南、北受到邊界斷層的控制,北部邊界斷層走向由近東西向到北東-南西向變化,向南傾斜,具有兩段式的特點,南部邊界斷層走向由西向東依次為東西向、北東-南西向、東西向,向南傾斜,具有三段式的特點。內部發(fā)育多條低級序斷層,東西向小斷層占主導地位,受邊界斷層的控制,多為南傾。結合巖心、測井資料,通過單井相、連井相、平面相分析,認為該區(qū)發(fā)育三角洲相中的三角洲前緣亞相,主要包括水下分流河道、河口壩、遠砂壩、前緣席狀砂和支流間灣等沉積微相。結合地震屬性分析和地震反演,提高了對無井地區(qū)儲層認識的準確度,完善了單純依賴井資料得出的砂體厚度和沉積相分布的結論。研究認為砂體主要分布在北部靠近濱縣凸起的地帶,東北部砂體最厚,中部地區(qū)砂體厚度居中,越靠近中部,斷裂越發(fā)育,構造位置相對較高,是油氣有利的聚集區(qū)域。
[Abstract]:Under the guidance of structural geology, structural analysis of oil area, sedimentology, seismic exploration principle and petroleum geology theory system, and based on previous studies, this paper makes use of seismic, logging, drilling, logging and production dynamic data. Through the combination of well and earthquake and static, using slicing technology, coherent volume technology, ant tracing technology and 3D visualization technology, etc., to carry out structural fine interpretation in geometry, In kinematics and dynamics, structural characteristics are studied and reservoir prediction is accomplished by combining qualitative analysis with quantitative prediction. Binan block 8 in Binnan Oilfield shows the structural pattern of the western trough, the central uplift and the eastern slope. The southern and northern boundary faults are controlled by the boundary faults. The strike of the northern boundary faults changes from near east to west to north to east to west, and tilts south to south. The southern boundary faults strike from west to east in order of east to west, and from north to south to west, and to the south from west to east, and to the north from east to south. East-west, inclined to the south, with a three-section characteristics. There are many low-order faults in the interior, and the small faults are dominated by east-west faults, which are controlled by boundary faults and tend to be southward. Combined with core and logging data, through the analysis of single well facies, contiguous well facies and plane facies, it is concluded that delta front subfacies are developed in the delta facies in this area, including underwater distributary channel, estuarine dam, far sand dam, etc. Sedimentary microfacies such as the front matting sand and the bay between tributaries. Combined with seismic attribute analysis and seismic inversion, the accuracy of reservoir recognition in no-well area is improved, and the conclusions of sand body thickness and sedimentary facies distribution obtained by relying solely on well data are improved. It is considered that the sandbody is mainly distributed in the area near Binxian uplift in the north, with the thickest sand body in the northeast. The thickness of the sand body in the central region is in the middle, the closer the sand body is to the middle part, the more developed the fault is, and the higher the tectonic position is, which is a favorable oil and gas accumulation area.
