据《石油商报》(记者王巧然)报道,中国石油正着手研制具有降低稠油黏度又可增加驱替液黏度两种功能的大分子降黏剂。这是记者3月中旬从中国石油股份公司科技管理部召开的“十三五”重大科技项目开题设计专家论证会上获得的信息。中国石油在新疆、辽河、大港和吐哈等油田拥有丰富的稠油资源。稠油开发方法包括热采和水驱,其中水驱普通稠油储量占稠油总储量30.1%,产量逐年增加。由于稠油黏度较大及油藏非均质性严重,普通稠油水驱进入高含水、
According to the “Petroleum Business Daily” (Reporter Wang Qiaoran), CNPC is working on the development of a macromolecule viscosity reducer that can reduce the viscosity of heavy oil and increase the viscosity of flooding fluid. This is the reporter in mid-March from the China National Petroleum Corporation, held by the Ministry of Science and Technology “Thirteen Five ” major scientific and technological project opening project design expert demonstration obtained information. PetroChina has abundant heavy oil resources in Xinjiang, Liaohe, Dagang and Tuha oilfields. Heavy oil development methods include thermal recovery and waterflooding, in which the common water-flooding heavy oil reserves account for 30.1% of the total reserves of heavy oil, the output increases year by year. Due to the heavy viscosity of heavy oil and serious reservoir heterogeneity, ordinary heavy oil flooding into high water content,
