摘要:
随着勘探开发技术的不断进步,火山岩储层压裂井次数逐渐增多。但由于火山岩储层具有岩性变化大、非均质性差、破裂压力高等特点,采用常规压裂改造技术往往达不到满意的增产效果。因此,针对查干地区火山岩油藏的储层地质特征和压裂改造难点,结合储层敏感性及岩石力学特征分析实验,优选出低残渣、低伤害的压裂液体系。在压裂工艺技术方面,进行了暂堵剂转向、全程伴注液氮工艺的研究,初步形成了一套较为有效的火山岩油藏储层水力压裂工艺技术体系。现场应用取得了显著的增产效果,对火山岩油藏的高效开发提供了一套有效的储层改造技术。
Abstract:
With the progress of the exploration and development technologies,the number of fracturing wells in volcanic reservoirs gradually increases.Since there are large changes in lithological characters,poor heterogeneity,and high fracture pressure in volcanic reservoir,it is difficult to reach a good stimulation effect by conventional fracturing techniques.Therefore,aiming at the geological characteristics and fracturing difficulties of volcanic reservoir in Chagan area,based on the analysis experiments of reservoir sensitivity and rock mechanics property,a low residue and damage fracturing fluid was selected.And then it was carried out studies on the temporary plugging agent and the entire process assisted liquid nitrogen injection technology.Finally,it was formed a more effective hydraulic fracturing technology system for volcanic reservoir.The field application obtained obvious stimulation effect.Thus,the technology can provide an effective stimulation method for high efficient development of volcanic reservoir.
