The development history and principle of interwell tracer testing single-well were investigated, the application conditions advantages different analyzed through analysis two types technologies test results in production process SMi oilfield with medium porosity low permeability, so as to provide reference for study same type oilfield. Tracer technology can master connection between injection w...

The BZ 34-1 oilfield is a typical gas cap edge water reservoir in the Bohai oilfield. main characteristics of were multi-phase sand body stacking and was composed three parts: cap, oil reservoir, water. actual production site results show that permeability difference multi-layer bodies has serious impact on development effect. This article establishes model numerical based total recovery degree...

One of the core contents intelligent oilfield is to develop proved oil resources economically and effectively. The way realize it make reservoir development in optimal state real time based on existing production conditions. Water flooding a commonly used technique after primary recovery. However, due influence formation heterogeneity, injected water breaks through high permeability layer traps...

Gas-liquid separator is an important surface equipment in oilfield development. Improving the separation efficiency of great significance to overall economic benefit oilfield. Spiral a high device that has been widely used, but at present, there are not enough studies on number spiral turns and pitches. In view this problem, paper analyzed gas–liquid separators with different pitches via fluent...

During nearly 25 years of water injection development in Gaotaizi reservoir LHP oilfield, due to poor physical properties, adaptability well pattern and difficulty establishing effective displacement between oil Wells, linear injection, infill adjustment refracturing tests have been carried out successively. Although certain effects seen, the are short unsatisfactory. In this paper, microscopic...
