摘要:

针对San Jorge盆地Sinopec Argentina工区作业井改造强度越大、效果越差的压后生产动态特征，通过典型井

的特征对比、结合储集体展布特征、凝灰质影响、地应力状态、水力裂缝扩展规律的研究，揭示了造成反常表现的主要因素。〖BP（〗对工区典型井特征参数进行对比，探讨

了反常储层改造特征的主控因素；〖BP）〗在此基础上，从裂缝规模、工作液体系、泵注参数等方面入手，进行了针对性的措施优化。实践证明，低强度改造工艺成功率更高

，相比中等强度改造提高了近10%；压后一年内，单井平均日产油高出30 m3，增效显著。针对工区特征采取的小规模、低强度的加砂改造方案提高了水力压裂作业成功率

和有效率，为下步工艺挖潜提供了新的技术思路。

Abstract:
 

In Sinopec Argentina area of San Jorge Basin, the stronger the stimulation

intensity of the operated wells, the worse the fracturing effect. Aiming at the dynamic producing performance after fracturing, through the

characteristic comparison of typical wells, the key factors causing the abnormal performance are revealed combining with the distribution

characteristics of the reservoir, the influence of tuff, the insitu stress state, and the study on the expansion law of hydraulic fractures. 〖BP

（〗Compare characteristic parameters of typical wells in the working area, and discuss the main controlling factors of abnormal reservoir

transformation characteristics. Staring from fracture scale, working fluid system, pump injecting parameters, etc., implement targeted stimulation

optimization.〖BP）〗Based on which the stimulation optimization has been performed from fracture scale, working fluid system and pump injection

parameters, etc. The practice proves that the lowintensity stimulation process has a higher success rate, which is nearly 10% higher than medium

intensity stimulation. Within one year after fracturing, the average singlewell daily oil production is 30 m3 higher, which is a significant

increase in production. Aiming at the characteristics of the working area, the modified plan with smallscale and lowintensity sand addition improves

the success rate and efficiency of hydraulic fracturing operations, providing a new technical idea for tapping the potential of the next process.
