摘要:
正宁地区储集层致密,裂缝是获产关键,目前裂缝特征及影响因素不明确。利用岩心、测井、实验测试等对长7裂缝特征、形成期次及裂缝发育因素进行综合分析。研究表明:裂缝类型主要为高角度或近垂直的构造裂缝,有效程度高,利于油气的纵向流动; 裂缝主要形成期次依次为印支—燕山期(有效性差),燕山—早喜山期(次形成期)和喜山期(主要形成期,有效程度高); 裂缝发育主要受应力场和岩层厚度、岩性物性等内外因素综合影响。研究可为正宁地区长7储集层的裂缝预测和高效开发提供重要指导。
Abstract:
In Zhengning area, the reservoir is dense,and the fracture is a key to high yield. But the characteristics of fracture and the influence factors are equivocal. Characteristics of fracture, formation period and development factors of Chang7 are analyzed by using data of core, logging and experimental test. The study results show that the types of fractures are main high angle or nearly vertical structural fractures with high efficiency, which are benefit for the longitudinal flow of oil and gas. The formation periods of fracture mainly include Indosinian to Yanshanian(poor effectiveness), Yanshan-early Himalayan(minor formation period)and Himalayan(main formation period, high degree of effectiveness). The control factors of fracture mainly include stress field, strata thickness and physical properties of lithology. The study results can provide an important guidance for the fracture prediction and the efficient development.
