渤海湾盆地冀中坳陷饶阳凹陷沙一下亚段页岩油可动量评价
|
摘要
以渤海湾盆地冀中坳陷饶阳凹陷沙一下亚段页岩油储层为例,对不同埋深层状和块状泥页岩储层岩心样品开展有机碳、热解和孔隙度等实验分析,结合研究层段测井曲线,弄清储层岩石压缩系数、原油压缩系数、地层水压缩系数和原始含油饱和度随深度的变化特征,确定块状和层状泥页岩储层最大天然可动油量随深度的变化特征。研究表明:除了在2 500 m未熟油阶段有一段高值区之外,沙一下亚段块状和层状泥页岩储层中弹性驱可动油量和溶解气驱可动油量均随深度增加而增大。块状储层弹性驱可动油率明显大于层状样品,其溶解气驱可动油率略小于层状储层。但单位体积块状泥页岩储层弹性驱可动油量、溶解气驱可动油量分别略小于和明显小于层状样品。块状和层状泥页岩储层弹性驱可动油量平均值分别为0. 13×10-3t/m3和0. 14×10-3t/m3,溶解气驱可动油量平均值分别为0. 56×10-3t/m3和1. 27×10-3t/m3。
The Es~(1L)shale oil reservoir in the Raoyang sag,Jizhong Depression,was studied to measure the reservoir rock,crude oil and formation water compressibilities as well as original oil saturation variation with depth,which enable the determination of the variation of the maximum movable oil reserves in massive and laminated shale core samples from different burial depth. These shale core samples were analyzed in terms of organic carbon content( TOC),Rock-Eval and porosity according to the well logging plot for the studied horizons. The results show that the movable oil reserves of natural depletion and dissolution gas drive increase with increasing burial depth both in massive and laminated shale reservoirs in Es~(1L),except for a sweat spot area located at a burial depth of 2 500 m at the immature production stage. Under natural depletion conditions,the movable oil ratio in massive reservoirs is markedly larger than that in laminated reservoirs,while slightly smaller under solution gas drive conditions. The movable reserves in per unit volume of massive shale oil reservoirs are slightly and obviously smaller than those in laminated shale oil reservoirs under natural depletion and dissolution gas drive respectively. The average movable reserves under natural depletion are 0. 13 × 10-3 t/m3 and 0. 14 × 10-3 t/m3,and those under dissolution gas drive are 0. 56 × 10-3 t/m3 and 1. 27 × 10-3 t/m3 in massive and laminated shale reservoirs respectively.
