低渗裂缝性高凝稠油油藏油井选择性堵水技术
摘要
Abstract
This paper investigated the water shutoff technology considering the selection of water shutoff agents, the mobility difference between the agents and crude oil before gelling, strength after gelling, operation process and parameters, etc. Based on the reservoir characteristics, crude physical properties and water production features in Niuxintou Oilfield. The study indicates that channeling of injected water exists in the oilfield due to the large difference in oil and water viscosity, formation heterogeneity and fracture induction and a suitable selective water shutoff technology has been developed for the oilfield. The technology was applied in two wells in the field, increased oil production and reduced water production. The technology has filled the gap in selective water shutoff for low permeability fractured high pour - point heavy oil reservoirs, and is helpful to the selective water shutoff in the similar oilfields.关键词
