Microseismic monitoring application for waterflooding in No.6 oil reservior of Yanchang Oilfield

Hao Shiyan,Wang Yongdong

Strategic Study of CAE 2012, Volume 14, Issue 4, Pages 8-11

Abstract:

This paper discusses the long 6 extend oilfield injection wells because the transfer group and the leading edge of microseismic monitoring of water. Yanchang Oil Field Oil Production Plant 4237 Zichang water injection wells set the direction of NEE to the front edge by the impact of in situ stress field in the direction of the strong. That injector network layout should also refer to the in-situ stress field direction and the original crack direction.

Using waterflood front monitoring to track the speed of water flow drive

Yang Zhidong,Zhou Jinyan,Chang Zhiyong,Zhang Jinrong,Han Mingyi

Strategic Study of CAE 2012, Volume 14, Issue 4, Pages 31-33

Abstract:

This study demonstrates results of waterflood front mapping and microseismic monitoring of Red-032 well zone. Microseismic monitoring results are in consistent with those of geological simulations and seismic amplitude distributions. It concludes that microseismic monitoring is capable of detecting locations of water flow drive, which provides evidence to optimize waterflood plan, improve injection/production methods, and increase waterflood efficiency.

A survey of physical activity among urban women in China

Shilin DENG MD, Tongyuan LIU,

Frontiers of Medicine 2009, Volume 3, Issue 4, Pages 463-469 doi: 10.1007/s11684-009-0081-y

Abstract: Few studies have been conducted to assess the level of physical activity (PA) of women in China. The purpose of this study was to describe the prevalence of PA among women in Wuhan and explore sociodemographic and behavioral correlation to PA for the population. A total of 1359 community-dwelling women (42.9713.60 years old) participated in this study. The long-version IPAQ was used to define the level of PA. 45.7% of women were considered physically active, and 27.5% were vigorously active. The proportion of physical inactivity was around 26.8%. The total and 4 domains of PA showed significant age, education level, and occupation variation. PA tended to be lower as the age declined. PA in transportation, housework, leisure time, and the total tended to be the lowest or the second lowest among the women aged 18–35 years old. PA tended to be lower as the level of education increased. Among the 5 indices, PAwas the lowest among women with college education, especially those with postgraduate education. PA tended to be the lowest among the women of office staff and instructor or technician. Generally, the total and 4 domains of PA showed significant age, education level, and occupation variation. Physical inactivity appears to be more common among younger women, or college-educated women, office ladies, and female instructor and technicians.
