地层损害是指降低储油层渗透性和减少储油注入能力的过程。多年来,钻井业只注重提高钻井效率和最少孔内事故。而固井业只满足于设计出在套管中不会卡住或过早凝固的水泥浆。因此,人们常常配制出使钻井和固井工作快速、经济的钻井液和固井液,而很少考虑它们对油井产量的影响。随着小型和边远地区油田开发项目的增加以及未下套管和射孔就完井的油井数量的增加,对地层的损害和控制也变 Stratigraphic damage is the process of reducing reservoir permeability and reducing the ability to inject oil. Over the years, the drilling industry has focused only on improving drilling efficiency and minimizing borehole accidents. The cementing industry is only satisfied with the design of the cement slurry that will not get stuck or prematurely set in the casing. As a result, drilling fluids and cementing fluids are often formulated to make drilling and cementing jobs fast and economical, with little consideration for their impact on well production. As the number of oilfield development projects in small and remote areas increases and the number of wells completed without casing and perforation increases, the damage and control of the formation also changes
