摘要:
準噶爾盆地瑪湖凹陷礫巖儲層超壓發育廣泛,超壓儲層具有物性好、產能高的特點,已經成為尋找優質儲層的重點勘探領域。基于巖石物理實驗和測井及試油資料,對超壓礫巖儲層測井響應特征進行了分析研究,確定了泥巖欠壓實是該區超壓的成因機理,超壓地層具有低電阻率、高聲波時差的特征。在欠壓實成因超壓下,地層的孔隙結構以基質孔和礫面孔為主,孔隙度滲透率關系呈現低孔隙度高滲透性的特征。構建了評價儲層品質的超壓物性指數,形成了用于定量評價儲層物性和油層評價的關鍵技術。基于此,確定了泥巖超壓和儲層孔隙結構是影響儲層產能大小的主控因素,建立了儲層分類的方法,在勘探評價中取得顯著的應用效果。
Abstract:
The overpressure conglomerate reservoirs in the Mahu sag of the Junggar Basin are extensive and characterized by good physical properties and high productivity. Such reservoirs have become key exploration targets for high-quality reservoirs. Based on petrophysical experiments, well logging and production test data, this paper analyzes the logging response characteristics of the overpressure conglomerate reservoir, and points out that the uncompact mudstone is the cause for the overpressure reservoir, and the overpressure formation has low Rt and high AC. In the uncompact formation, matrix pores and conglomerate surface pores are dominant, the porosity is low while the permeability is high. Finally the overpressure physical property index for evaluating reservoir quality is constructed, and the key technology for quantitative evaluation of reservoir physical properties are established. Based on them, the factors affecting the reservoir productivity are attributed to the overpressure caused by mudstone and the pore structure, and the reservoir classification method is developed. These methods are applicable and effective in field exploration and evaluation.
