低渗透油藏水平井联合井网型式研究
摘要
Abstract
With the rapid reserve increment of low permeability reservoirs and the development of horizontal well technique, the application of horizontal wells in low permeability reservoirs is expanding to the field scale and it is necessary to study the related horizontal well patterns. This paper is based on the low permeability reservoir parameters background, and the results show that the injection-production ratio should not be too high or low due to the larger control area of horizontal well for pure horizontal well patterns, and the parallel interlace well pattern is the optimal well pattern; for the vertical-horizontal composite well patterns, the ultimate recovery of different well patterns is similar while the water cut curves are much different, and the development performance of five spot vertical injector and horizontal producer pattern is better, especially combined with multi-fracturing techniques. In addition, the design for vertical-horizontal composite well patterns is more flexible and some special vertical-horizontal well patterns can achieve great development performance by optimization of the well spacing.关键词
