Application of Natural Gas Huff-and-puff in Super-deep Heavy Oil Development

摘要：

Tuyuke oilfield is a super-deep heavy oil field, with the reservoir burial depth of 3000m to 3700m, increasing gradually from east to west, with the thickness of oil layer being between 35~90m. The surface crude viscosity is 10, O00mPa.s (50℃) and in-situ viscosity is 154mPa.s (99℃ ). Due to the relatively low ratio of KH/μ,Oil wells have no natural productivity. The stable production per well was only 2-3t/d after fracturing, the oilfield isdifficult to be recovered economically To improve the development of the oilfield, we designed the natural gas huff-and-puff optimized main parameters such as total injected gas volume, shut-in time and gas injection rate.
