摘要
塔河油田超稠油是奥陶系碳酸盐岩岩溶缝洞型超重质未饱和底水油藏，具有超深、超稠、高黏、高密度、高含H2S、高矿化度等特点，且酸压作业规模大，开发与地面集输难度大。西北油田分公司通过科研攻关，解决了超稠油集输处理的系列技术难题，在上游板块首次创新了掺稀降黏集输技术、首次应用高含H2S稠油气提法脱硫技术、突破稠油脱水工艺，实现了超稠油的密闭集输。
Abstract
As an Ordovician carbonate karst vuggy extra-heavy unsaturated bottom-water reservoir, the super heavy oils in the Tahe Oilfield are featured by ultra-deep, ultra-thick, high viscosity, high-density, high content of H2S, high salinity and other characteristics. Acid fracturing is in large scale, and development and ground gathering are difficult. The SINOPEC Northwest Oilfield Company, through scientific research, has solved the problems in the gathering and transportation of ultra-thick crude oil. The gathering and transportation technique by mixing light oil to decrease viscosity is innovated. The desulfurization technique by gas extraction is applied for the first time on heavy oil rich in H2S, breaking heavy oil dehydration process to achieve the closed gathering of ultra-heavy oil.
