【摘要】：敖南油田茂402-3區(qū)塊葡萄花油層儲層薄差,整體開發(fā)實施風險較大。為了進一步搞清茂402-3區(qū)塊地質特征,利用地震資料,結合區(qū)塊內新完鉆首鉆井資料,對區(qū)塊構造、儲層等地質特征進行再認識,描述斷層與砂體接觸關系。在此基礎上優(yōu)化水平井方案設計,開展儲層優(yōu)選及跨斷層水平井優(yōu)化設計研究,實現(xiàn)斷層兩側同一油層合理動用,探索提高外圍油田斷裂復雜區(qū)塊動用程度的方法,確保區(qū)塊有效開發(fā)。本文充分運用鉆井、地震、錄井、測井等資料,以合成地震記錄為橋梁,對研究區(qū)的葡萄花進行了精細解釋和編圖,并進行了地震反演和儲層預測研究,在此基礎上,對地層界面特征、地層分布、斷裂切割關系、圈閉特征等做了較為系統(tǒng)的研究。針對研究區(qū)儲層特征,分別開展了常規(guī)屬性、分頻屬性、甜點屬性和反演屬性切片等多種屬性方法研究,并結合反演屬性進行多期綜合刻畫,完成了層間有利發(fā)育區(qū)的綜合預測。并以構造分析成果、地震屬性分析成果及反演預測成果為基礎,從沉積環(huán)境、構造條件、主控因素等角度出發(fā)綜合分析識別砂體發(fā)育區(qū)。再綜合已知鄰井油氣情況等條件,建議了5個有利鉆探井位,在此基礎上開展三維地質建模,并用數(shù)值模擬軟件進行水平井優(yōu)化設計研究,優(yōu)選出平井井網形式、水平段方向、水平段長度、注水井到水平井垂直距離及水平井射孔位置。
[Abstract]:The reservoir thickness of Putaohua reservoir in Mao-402-3 block of Aonan oilfield is poor, and the risk of overall development and implementation is great. In order to further understand the geological characteristics of Mao-402-3 block, using seismic data, combined with the new drilling data in the block, the geological characteristics of block structure and reservoir are re-recognized, and the contact relationship between fault and sand body is described. On this basis, the design of horizontal wells is optimized, and the optimal selection of reservoirs and optimal design of horizontal wells across faults are carried out to realize the rational production of the same reservoir on both sides of the fault, and to explore ways to improve the production degree of complex blocks of faults in peripheral oil fields. Ensure effective development of the block. This paper makes full use of drilling, seismic, logging and other data, taking synthetic seismic records as a bridge, carries out fine interpretation and mapping of the grape flower in the study area, and carries out seismic inversion and reservoir prediction studies, on the basis of which, The characteristics of stratigraphic interface, stratigraphic distribution, fracture cutting relationship and trap characteristics are systematically studied. According to the reservoir characteristics of the study area, the conventional attribute, the frequency division attribute, the dessert attribute and the inversion attribute slice are studied separately, and the inversion attribute is combined with the inversion attribute to carry on the multi-period comprehensive characterization. The comprehensive prediction of the favorable development area between layers has been completed. Based on the results of structural analysis, seismic attribute analysis and inversion prediction, the authors comprehensively analyze and identify the sand body development areas from the point of view of sedimentary environment, structural conditions and main controlling factors. On the basis of the known oil and gas conditions of adjacent wells, it is suggested that five favorable drilling wells should be drilled. On this basis, 3D geological modeling is carried out, and the optimization design of horizontal wells is studied by numerical simulation software, and the horizontal well pattern and horizontal section direction are selected. Horizontal section length, vertical distance from injection well to horizontal well and perforation position of horizontal well.
