摘要:

塔里木盆地迪北气藏侏罗系阿合组为典型的低孔、低渗致密砂岩储层,非均质性强,油气分布复杂。针对研究区有效储层物性下限不清的问题,基于储层物性、录井、试油与压汞资料,结合核磁共振和低温吸附实验测试结果,综合运用最小流动孔喉半径法、排驱压力法、束缚水饱和度法、含油产状法、试油法和分布函数曲线法等 6 种方法,对迪北气藏阿合组有效储层物性下限进行了研究。 结果表明,迪北气藏阿合组有效储层孔隙度下限为 2.6%,渗透率下限为 0.08 mD;砂砾岩夹泥岩段(J1a1)→上砂砾岩段(J1a2)→下砂砾岩段(J1a3)储层物性逐渐变差,相应的储层物性下限也逐渐变低;J1a1,J1a2 和 J1a3 有效储层孔隙度下限分别为 3.1%,2.65%和 2.3%,渗透率下限分别为 0.14 mD,0.09 mD 和 0.065 mD。 有效储层物性下限的研究对迪北气藏的储层评价、储量计算和开发方案设计等均具有一定的指导意义。

Abstract:

 

The Jurassic Ahe Formation in Dibei gas reservoir is characterized by low porosity and low permeability tight sandstone reservoir, strong heterogeneity and the complex oil and gas distribution. The lower limit of effective reservoir properties is uncertain, which is critical for reservoir evaluation, gas reserve and resources computation. Based on the data of reservoir properties, logging, oil testing and mercury measurement, combined with NMR and lowtemperature adsorption experiment results, this paper applied six methods including minimum flow pore throat radius, displacement pressure, bound water saturation, oil occurrence, oil testing and distribution curve to determine the lower limit of effective reservoir properties of Ahe Formation in Dibei area. The result shows that the lower limit of porosity and permeability of the Formation are 2.6% and 0.08 mD respectively. From J1a1, J1a2 to J1a3, that is the three lithology members from top to bottom, reservoir properties gradually decrease, and the lower limits of reservoir properties gradually decrease correspondingly. The lower limits of porosity of J1a1, J1a2 and J1a3 reservoir are 3.0%, 2.6% and 2.2% respectively, and the lower limits of permeability are 0.14 mD, 0.09 mD and 0.065 mD respectively. The understanding of lower limit of reservoir properties has some significance for the resource and gas reserve re-evaluation, reservoir evaluation and gas development design in Dibei gas reservoir.
