The reservoir in different parts of buried-hill draping zone is often quite different, so it great significance to clarify the characteristics for exploration and development. Based on core, well logging, seismic data production data, oil layer Ⅱ lower second member Dongying Formation L oilfield, Bohai Bay Basin, offshore eastern China are systematically studied. Analyses facies, well-seismic c...

Abstract After a century of development, China's petroleum industry has introduced numerous and various industrial heritage elements, which collectively embody the value significance heritage. Currently, all levels government departments are trying to protect heritage, but only limited types elements included in official conservation lists, is not conducive systematic To achieve this study glob...

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.

22 Do natural resource windfalls increase the risk of armed conflict within a country? Yu-Hsiang Lei and Guy Michaels investigate the impact of giant oilfield discoveries on the likelihood of civil conflict.

The largest ultra?deep (>7000 m) strike?slip fault?controlled oilfield was found in the tight Ordovician carbonates Tarim Basin. Because oil production wells Fuman Oilfield generally have bottom water, a reasonable design is of significant importance for extending water?free recovery period and improving recovery. However, there no economical effective quantitative method to determine capaci...

Modeling and Computational Strategies for Optimal Development Planning of Offshore Oilfields under Complex Fiscal Rules Vijay Gupta and Ignacio E. Grossmann Department of Chemical Engineering, Carnegie Mellon University Pittsburgh, PA 15213 Abstract The main goal of this paper is to extend a simple NPV (net present value) based optimal oilfield development planning model to include complex fisc...

When designing automated management systems for oilfield development one of the main problems is the uncertainty of control object stemming from natural factors. Field properties’ identification becomes a key task here. Field model adjustment plays a crucial role in this process. It is clear that history matching, as well as control, should be conducted on different time scales. Under the close...

The phenomenon of the cementing annulus micro clearance gas channeling directly influences cement job quality and oilfield production, so accurately describing the flow rule of cementing annulus micro clearance gas channeling is the core and "bottleneck" problem of controlling gas channeling effectively. From the perspective of the micro particle motion and based on the lattice Boltzmann method...

It is the important technology to take the optimum control of automatic drilling in the course of oilfield drilling in accordance with actual situation. Due to the complexity of drilling process and the non-linear relationship between input and output of drilling system; it’s difficult to acquire satisfied results to adopt general control method. This article presents a new control method which...

A modelling effort was made to try to predict the life of downhole tubes or casings, synthetically considering the effect of service influencing factors on corrosion rate. Based on the discussed corrosion mechanism and corrosion processes of downhole tubes, a mathematic model was established. For downhole tubes, the influencing factors are environmental parameters and stress, which vary with se...
