【摘要】：本論文的研究問題是朝陽溝油田的精細開發(fā)時,其中構造解釋不細而造成的認識不清等問題,通過使用井震結(jié)合的三維地質(zhì)模型來控制表現(xiàn)該地區(qū)的構造特征,獲得了一定新的思路。論文中使用的測井曲線如聲波曲線受到擴徑等影響,基線不一致,出現(xiàn)了偏移,甚至曲線范圍不一致的情況,尋找了測井曲線標準化的方法,分別對自然電位和聲波曲線等進行標準化。密度曲線使用相關曲線的擬合方法來重新制作密度曲線。本次項目使用地震來控制構造形態(tài),單井的數(shù)據(jù)來控制位置,在這樣的分析中來完成朝44區(qū)塊斷層解釋和斷點的組合。綜合的使用測井數(shù)據(jù)中的斷點數(shù)據(jù),分層深度和提取地震屬性,從點到面的對斷層分形分析,落實構造的形態(tài),完成朝44油田的斷層模型。在斷層模型的約束下,把地震解釋的層位和測井分層深度統(tǒng)一,制作出朝44區(qū)塊的構造模型,并在沉積相模型的約束下完成了該區(qū)塊的精細屬性模型。通過本論文,得出了完整的井震結(jié)合三維地質(zhì)建模的流程和方法,這樣在后續(xù)該區(qū)塊開發(fā)過程可以有很大的價值。
[Abstract]:The research problem in this paper is that in the fine development of Chaoyang Gou oilfield, the structural interpretation is not very good and the understanding is not clear, and so on. The 3D geological model combined with well and earthquake is used to control and express the structural characteristics of this area. Some new ideas have been obtained. The logging curves used in this paper, such as the acoustic curves are affected by the expansion of the diameter, the baseline is inconsistent, the migration occurs, and even the range of the curves is inconsistent. The method of logging curve standardization is found. The natural potential and acoustic wave curves were standardized respectively. The density curve was remade by the fitting method of the correlation curve. The earthquake was used to control the structure shape in this project. Single well data to control the location, in such an analysis to complete Chao44 block fault interpretation and fracture point combination. Comprehensive use of logging data in the fracture point data, stratification depth and extraction of seismic attributes. The fractal analysis of faults from point to surface, the implementation of structural shape, the completion of the fault model of Chao44 oilfield. Under the constraints of fault model, the seismic interpretation of the horizon and logging stratification depth unified. The structural model of Chao44 block is made, and the fine attribute model of Chao44 block is completed under the constraint of sedimentary facies model. Through this paper, the complete process and method of well shock combined with 3D geological modeling are obtained. In this way in the subsequent development process of the block can have great value.
