In addition, the reservoir rock shows medium to strong stress sensitivity because of the unconsolidated cementation, resulting in low oil flow velocity. Therefore, it is difficult to obtain sufficient information to make a reasonable interpretation. Water-injection well test is a good way to solve this problem. Based on analysis of the mobility ratio, the effects of stress sensitivity and threshold pressure gradient, a mathematical model for water-injection well test in low-permeability unconsolidated reservoirs was established. Since this model has strong nonlinearity, stable finite-difference scheme and Newton-Raphson iteration method were adopted to obtain the arithmetic solution. The pressure performance and influencing factors were also evaluated, and the typical well testing curves for analysis of real datawere plotted., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=tdiloIJuzCkXGZFNjIVmMw==, pdfFileSize=2932882, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
