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...

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...

C oilfield is a heavy oil field developed by horizontal wells and single sand body in Bohai oilfield. The edge bottom water of the reservoir active natural energy development mode adopted. comprehensive cut was 95.3%, which had entered stage high production. Some reservoirs were limited crude viscosity column height. Under condition existing well pattern, some reserves not produced or degree pr...

After long-term water flooding development in old oilfields, oil layers are generally flooded. Accurate and rapid recognize the layer is key to later infill well layout plan adjustment. In this paper, taking Xingbei area of Daqing Oilfield as an example, on basis clarifying characteristics water-flooded curve, through logging curve optimization, data preprocessing algorithm model optimization p...

Although methanogenic degradation of hydrocarbons has become a well-known process, little is known about which crude oil tend to be degraded at different temperatures and how the microbial community is responded. In this study, we assessed the methanogenic crude oil degradation capacity of oily sludge microbes enriched from the Shengli oilfield under mesophilic and thermophilic conditions. The ...

The study discusses the characteristics of Jurassic reservoir in Shenquan Oilfield Xinjiang. Qiketai Sanjianfang formation mainly develops delta front facies and shore shallow lake sand bodies.The lithological are fine sandstone siltstone, physical properties target layer medium porosity permeability. space is pore type, composed secondary pores, including intergranular dissolved intragranular ...

Heavy oil is an important unconventional resource with huge availability worldwide, which also forms the primary source in Fengcheng oilfield, XinJiang, China. The elastic properties and consolidation status of heavy sands are significant values as they can provide guidance for reservoir exploration production. However, due to lack detailed rock physics investigation knowledge about their micro...

Herein, we introduce a low-cost, available, renewable, and effective solid adsorbent used for oilfield-produced-water treatment using straightforward process. In the present study, sheep dung ash was prepared same way this waste is produced in rural areas when as source of energy cooking heating: by burning with direct flame. The characterized FTIR, EDX, SEM analysis techniques. feasibility red...

HYW (Hong Yi Wu line) heavy oil emulsion in Xinjiang Oilfield (Karamay, China) is a kind of with high viscosity and emulsification. Its reaches 120,000 mPa·s at 40 °C. The has no demulsification. Even if the demulsification temperature 90 degrees, concentration demulsifier 260 mg/L. In this paper, new process thermochemical after blending studied. First, SE low-viscosity 640 water cut 90% was s...
