塔里木盆地西达里亚油田三叠系油藏数值模拟开采机理研究

STUDY ON THE NUMERICAL SIMULATION OF PRODUCTION MECHANISM FOR THE TRIASSIC RESERVOIRS OF XIDALIYA OILFIELD,THE TARIM BASIN

该文针对西达里亚油气田的开发已处于高含水阶段的特点,应用油藏数值模拟软件,以单井模型为基础,从采油速度、垂向渗透率、避气避水高度及打开程度的敏感性这4个方面对油藏开采机理进行了研究,为西达里亚油气田进一步挖潜、提高采收率提供了理论依据。

According to the characteristics of the high watercontent stage in which the development of Xidaliya oil and gas field is, the production mechanism of reservoirs is studied from production rate,vertical permeability,the distance from perforation to gas cap or to bottom water and the sensibility of penetration degree four respects,using reservoir numerical simulation softwares and based on singlewell models.This provides theoretical bases for the further potentialtapping and recoveryraising of Xidaliya oil and gas field.
