Abstract Immiscible WAG injection was successfully used to enhance the oil recovery in thick, heterogeneous reservoir east of Beier area Daqing field. After a five year test period, water cut is basically stable and production continuously increasing. The factor now more than 3% higher ultimate by injection, predicted be 8% higher. Changes have taken place entry profile well. Gravity segregation occurs reservoir. Areal sweep conditions are improved thickness liquid increased.

Feature selection is a powerful tool for choosing feature subset of relevant attributes and has been widely used in many research fields, including power system. In this paper, we have introduced two-step algorithm that combines the advantages Grey Relation Analysis (GRA) Binary Particle Swarm Optimization (BPSO) search method. The proposed method aims to solve problem massive-scale system find these which are highly related target scenario. This would eliminate some features based on GRA...

The recognition of medical images, especially endoscopic ultrasound has the characteristics changing images and insignificant gray-scale changes, which requires repeated observation comparison by staff. In view above-mentioned imaging, a system scheme suitable for image processing is proposed, can analyze biliary tract, gallbladder, abdominal lymph nodes, liver, descending duodenum, duodenal bulb, stomach, pancreas, pancreatic there are total 10 ultrasonic organs, including 21 kinds...

<title>Abstract</title> Background: The prognosis of endometrial cancer(EC) is good in the early stage, but not late stage and relapse stage. Its morbidity mortality are increasing. Traditional pathological classification risk stratification have obvious limitations. Thus, It great urgency to search for more prognostic molecules cancer develop individualized treatment strategies. Methods: Two gene expression profiling datasets (GSE39099, GSE63678) were found from Gene Expression Omnibus(GEO)...

As key and core element construction Education,” engagement teaching work university teachers issue that determines level affects quality talent cultivation universities. Using literature review method, this study analyzed 39 relevant literatures retrieved from China National Knowledge Infrastructure (CNKI) 1997 to 2023. concept, connotation, current situation, influencing factors, improvement...

Cooling-air grinding is one of important green technology. performances for 40Cr are tested in this paper using cooling-air generator. Main performance influencing factors and analyzed, such as air temperature, wheel granularity, amount feed so on. results showed that roughness surface specimen can reach to precise standard. So replace traditional experiment. This study the promotion application technology has significance reference.

abstract:Remote sensing technology is playing anincreasingly important role in the investigation and exploration of oil gasresources. Using thermal infrared remote to detect offshoreoil gas resources one new methods, but there are many uncertainties. Inthis paper, MODIS data used explore availabilityin North Yellow Sea Basinthrough extracting temperature anomaly areas. Result shows that this methodcan be effective assisting exploring undersea resources.
