摘要:

        针对低渗透油藏存在启动压力梯度和压敏效应的问题,在前人研究的基础上,根据水电相似原理,应用等值渗流阻力法,建立了压裂水平井补孔和不补孔两种情况下的产能公式,并且与其他压裂水平井产能公式与数值模拟结果进行了对比。对比结果表明:如果水平井压裂后补孔,建议使用本研究建立的公式;如果压裂后不补孔,建议使用郎兆新的计算公式。建立的压裂水平井产能公式,对目前低渗透油藏利用水平井进行开发具有重要的理论和现实意义。

Abstract:

Based on the problem for the starting pressure gradient and strong stress sensitivity for the low permeability reservoirs,the paper has established the production formula for horizontal wells with hydraulic fractures in different circumstances.If horizontal wells with hydraulic fractures are not partially perforated,the established production formula will be an effective method,and if horizontal wells with hydraulic fractures are partially perforated,the Langzhaoxin production formula will be an effective method instead of other different methods for horizontal wells with hydraulic fractures.The established production formula of the horizontal wells with hydraulic fractures has an important theoretical and practical meanings for low permeability reservoirs.

Key words:  low permeability reservoir, hydraulic fracturing, horizontal well, production, development
