摘要
依据川西洛带蓬莱镇组气藏地质、压裂及试井资料,通过定性及灰关联分析,结果表明压裂层段岩性、孔隙度及地应力特征是影响压裂效果的主要因素。根据试井解释理论,综合运用压前压后试井资料分析试井曲线形态特征及地层参数变化,动态认识压裂层段储渗特征,深入剖析评价气藏压裂效果,为气藏今后压裂选层、措施方案改进提供依据。研究方法对同类型气藏的科学管理开发具有一定的指导和借鉴意义。
Hydraulic fracture is necessary to put the compact and low permeability reservoir into production. According to the information of geology, fracture and well test about Luodai J3P in Depression of west Sichuan basin, the results show that lithology, porosity and the ground stress' strait of fracturing layers is the main factor in affecting fracturing effect; basing on the interpretive theory of well test and comprehensively using the information of pre and post fracturing well testing, the paper analyses the morphological trait of well testing curve and changes in formation parameter, and knows permeable-stored trait, and deeply analyzes and assesses the fracturing effect of the reservoir, which provides proofs for fracturing formation selection and improvement of method and scheme. The research method has certain directive meaning.
