摘要

针对吉木萨尔页岩油衰竭式开发采收率低、注水吞吐效果差的问题,通过油气相态实验和油藏数值模拟方法开展了页岩油储层CO₂吞吐技术适用性研究,指导现场CO₂吞吐技术实施。结果表明:相较于CH₄,CO₂与吉木萨尔页岩油的相互作用更好,在地层压力和地层温度条件下,CO₂在原油中的溶解气油比为497.83 m³/m³,原油黏度降低70.65%,原油体积膨胀2.05倍;对于典型页岩油井,多周期CO₂吞吐可提高采收率9.43个百分点,原油产量可提高31 472.40 t。随着裂缝间距缩短和储层孔隙度增加,CO₂吞吐增油效果逐渐变好,渗透率和含油饱和度对CO₂吞吐效果的影响较小。矿场试验结果表明,CO₂吞吐可有效提高页岩油采收率,在无裂缝窜扰条件下,增油效果更优。研究成果对页岩油高效开发具有一定借鉴意义。

Abstract

To address the problems of low recovery rate and poor water injection huff-n-puff effect in the depleted development of Jimsar shale oil. A study on the applicability of CO₂ huff-n-puff technology in shale oil reservoirs was carried out by means of hydrocarbon phase experiments and numerical simulation methods for reservoirs to guide the implementation of CO₂ huff-n-puff technology in the field. The results show that Compared with CH₄, CO₂ interacts better with Jimsar shale oil. Under the conditions of formation pressure and formation temperature, the solution gas-oil ratio of CO₂ in crude oil is 497.83 m³/m³, the crude oil viscosity is reduced by 70.65%, and the crude oil volume is expanded by 2.05 times; for typical shale oil wells, multi-cycle CO₂ huff-n-puff can improve the recovery rate by 9.43 percentage points and crude oil production by 31 472.40 t. With the shortening of fracture spacing and the increase of reservoir porosity, the effect of CO₂ huff-n-puff on oil enhancement gradually becomes better, and the influence of permeability and oil saturation on the effect of CO₂ huff-n-puff is relatively small. The results of the field test show that CO₂ huff-n-puff can effectively enhance the recovery rate of shale oil, and the oil enhancement effect is better under the condition of no fracture disturbance. The research results have some implications for the efficient development of shale oil.

Key words： shale oil; CO₂ huff-n-puff; enhanced recovery; PVT experiment; numerical simulation; Jimsar
