INTRODUCTION Oil and water well is an important basic estab- lishment in oilfields. In many oilfields, there are many different damages in the well’s casing walls after its development for a period of time. They will affect the normal production of damaged wells and adversely influence the neighbouring wells and the block, and threaten steady production. There are different kinds of damages due to multiple problems in the casing walls, for example, corrosion, perforation, decreased diame… 相似文献

INTRODUCTION The imaging and measurement of multiphase flows has received much attention in recent years, largely because of a need in the oil industry to measure the mass flow rates of oil, water and gas in production pipelines, and the ability to see through objects and make quantitative measurements of the enclosed ma- terials and structures has wide range of applications. However, measurement over a wide range of flow regimes and the ability to very accurately measure the mass flow rat… 相似文献

INTRODUCTION Oil-water-gas multiphase mixed transport in oil pipe is extensively used in ocean oil industries. How to measure the volumetric fractions of oil-water-gas multiphase flow is an important subject of study in the oil industry. Related research work was started in the 1980s. The measurement of component ratios in multiphase flows using γ-ray attenuation was first suggested by Abouelwafa and Kendall (1980), and the technique has been used in many current com- mercial multiphase… 相似文献

Measurement of oil volume fraction and velocity distributions in vertical oil-in-water flows using ERT and a local probe 总被引：2，自引：0，他引：2
INTRODUCTION The need for metering multiphase flow in the petroleum industry has been evident for many years. Considerable research has been conducted into this field for developing a suitable flowmeter which can be used in industrial environments. Various tech- nologies have been employed, and among which the tomographic techniques are increasingly being used. Process tomography is an emerging measure- ment technology with applications in a broad range of industries. It is non-invasive a… 相似文献
