【摘要】：敖南油田茂402-3区块葡萄花油层储层薄差,整体开发实施风险较大。为了进一步搞清茂402-3区块地质特征,利用地震资料,结合区块内新完钻首钻井资料,对区块构造、储层等地质特征进行再认识,描述断层与砂体接触关系。在此基础上优化水平井方案设计,开展储层优选及跨断层水平井优化设计研究,实现断层两侧同一油层合理动用,探索提高外围油田断裂复杂区块动用程度的方法,确保区块有效开发。本文充分运用钻井、地震、录井、测井等资料,以合成地震记录为桥梁,对研究区的葡萄花进行了精细解释和编图,并进行了地震反演和储层预测研究,在此基础上,对地层界面特征、地层分布、断裂切割关系、圈闭特征等做了较为系统的研究。针对研究区储层特征,分别开展了常规属性、分频属性、甜点属性和反演属性切片等多种属性方法研究,并结合反演属性进行多期综合刻画,完成了层间有利发育区的综合预测。并以构造分析成果、地震属性分析成果及反演预测成果为基础,从沉积环境、构造条件、主控因素等角度出发综合分析识别砂体发育区。再综合已知邻井油气情况等条件,建议了5个有利钻探井位,在此基础上开展三维地质建模,并用数值模拟软件进行水平井优化设计研究,优选出平井井网形式、水平段方向、水平段长度、注水井到水平井垂直距离及水平井射孔位置。
[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.
