志丹探区长2油藏属于构造-岩性油气藏,在对其储层物性、孔隙结构、渗流特征、敏感性分析的基础上,认为油层物性及地层压力较低是影响产能的主要静态因素;开采过程中原油边界层的变化、胶结物成分的变化、油水乳化液的影响及地层微粒分散、运移造成的堵塞是影响产能的动态因素。通过压裂改造、加强注水可提高因静态因素引起的油井产量,对于动态原因引起的油井产能低,建议实施油层深部综合解堵的增产措施。
Based on the analysis of reservoir physical properties, pore structure, seepage characteristics and sensitivity, the reservoir of Zhidan Exploration Area 2 belongs to the tectonic-lithologic reservoirs. It is considered that the reservoir physical properties and formation pressure are the main statics Factors such as the change of the boundary layer of crude oil, the change of cement composition, the influence of oil-water emulsion and the dispersion of formation particles and the blockage caused by migration are the dynamic factors that affect the production capacity. Through fracturing, strengthening water injection can increase well production caused by static factors. For oil wells with low dynamic productivity, it is suggested to increase oil production by deep block removal.
