摘要
Abstract
The upper Guantao Formation of Gudao Oilfield features changeful sedimentary rhythmic, which is different in different geological formations. Even in the same formation, the lithology, physical property and permeability are diverse in different locations, which causes oil recovery factor low when perforating in ordinary way. Proposed is a variable density optimization perforating method for formation with different physical properties in condition that other perforating parameters(optimized perforation length, perforation diameter, and shot phase, etc. ) are constant. Analyzed is the feasibility of applying variable density perforating technology to adjust production profile and improve water flooding effect and polymer flooding effect. Summerized is the summary skin coefficient and well capacity calculating formula based on geology characteristics of this area. It is concluded that shot density for Gudao oilfield is 12～18 hole/m. Practical applications show that variable density perforating method for different physical property formations improves polymer flooding effect and plays an important role in guiding productivity test and maturing fields development.关键词
