Abstract:Basedonthe poor reservoir conditions inlow porosity,lowpermeability,and lowabundanceoilfields,reservoirs are highly susceptible to damage during driling and completion operations,resulting in low production rates and poor economic performanceof oil and gas wels.Inresponse to this issue,this studyestablishes a mathematical model for productivityevaluation focusing on five commonly used stimulation techniques:horizontal wels,multilateral horizontal wels,fracturing,acidizing,and deep-penetration perforation.The resultsshow that multilateral horizontal wellsand fractured horizontal wells have the most significant production enhancementefects,followed by conventional horizontal wels and fractured vertical wells which show relatively good results,while acidizing and deep penetration perforation have relatively poor stimulation outcomes.

随着油气田开发与开采的不断深人,以页岩油、页岩气、致密油、致密气等为主要代表的非常规油气成为了储量增加的主要类型,这些资源分布广泛,储量巨大,但一般以低孔、低渗、低丰度为主要特点,单井产能较低,在生产过程中往往需要采用不同形式的增产方式来提高产量,达到更好的经济效益。(剩余5347字)
