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...

It is difficult to excavate the remaining oil in thin differential reservoir and oil-water reservoir. The can be excavated by means of static dynamic analysis method microstructure continuously improve recoverable benefit oilfield. Based on this, this paper studies potential excavation methods

During oilfield development, there exist multi-cycle gas–water mutual displacement processes. This means that a cycling process such as water driving gas–gas driving water–water driving gas is used for the operation of injection and production in a single well (such as foam huff and puff in single well or water-bearing gas storage). In this paper, by using coreand micro-pore scales model, we st...

The extract of Ligustrum lucidum Ait. seeds, as green and eco-friendly corrosion inhibitors, have been investigated on the corrosion inhibition of Q235A steel in 1M hydrochloric acid solution at 60°C by weight loss and potentiodynamic polarisation techniques. The inhibition efficiency of the extracts varies with extract concentration from 10 mg/L to 1000 mg/L and the highest one reaches to 95.0...

Abstract—Well logging records can help to answer many questions from a wide range of special interested information and basic petrophysical properties to formation evaluation of oil and gas reservoirs. The accurate calculations of porosity in carbonate reservoirs are the most challenging aspects of the well logging analysis. Many equations have been developed over the years based on known physi...

With the gradual end of polymer flooding in blocks type II oil reservoirs, scale subsequent water production and injection fields is increasing. As can be seen from production, due to different factors such as reservoir properties injection-production rates, various indicators block vary greatly, which brings difficulties prediction later stage. Therefore, it urgent carry out follow-up research...

With the continuous development of oilfield, number oil and water wells is increasing, casing loss on rise. This paper analyzes researches to further understand causes loss, proposes measures protect in western part area A. It summarizes experience methods “six checks, six preventions controls” for protection, which provides direction preventing a basis reasonable development.
