The relative permeability curve is an important basic data for the preparation and dynamic analysis of oilfield development ( adjustment ) schemes. Due to different types curves in water cut stages, there a large deviation prediction indexes ultra-high stage according early development. In order study change process, based on morphological characteristics 118 28 coring wells Xingbei area after ...

An experimental study of anaerobic treatment was performed by hybrid upflow anaerobic sludge blanket (HUASB) reactor to treat produced water (PW) of an onshore crude oil terminal (COD: 1597 mg/L, NH3-N: 14.7 mg/L, phenol: 13.8 mg/L, BOD5: 862 mg/L, sodium: 6240 mg/L and chloride 9530 mg/L). The produced water with high salinity and other toxic substances will inhibit the methanogens performance...

Nowadays, water savings on industrial plants have become a significant concern for various and sections. It is vitally essential to propose applicable efficient techniques retreat produced from onshore offshore production units. This paper aimed implement the PFF (Photo Fenton Flotation) method optimize treatment procedure, as it two-stage separation technique. The measurements were recorded HF...

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 ...

Commercial and centralized oilfield wastewater disposal facilities (COWDFs) are used in the Western United States for the disposal of formation water produced from oil and natural gas wells. In Colorado, New Mexico, Utah, and Wyoming, COWDFs use large evaporation ponds to dispose of the wastewater. Birds are attracted to these large evaporation ponds which, if not managed properly, can cause wi...

The casing damage of oil and water wells has seriously affected the normal production oilfield. This paper analyzes high occurrence in Saertu layer, finds that there is a contradiction between injection formation prevention control damage. Although wellhead pressure can be guaranteed to lower than its fracture during production, injected energy at includes potential kinetic energy. Because rela...
