王庄油田郑408块油藏潜在敏感性评价
|
摘要
王庄油田是亿吨级敏感性稠油油藏,但对于潜在敏感性评价和影响因素的深入试验研究仍不足。为此,以王庄油田郑408块为例,通过组分试验分析和流体流动性试验测试,对稠油油田油藏的粘土成分、微观特点及成岩作用等物理化学特征和变化规律进行分析,认为研究区油藏具有中-强水敏、中等酸敏、盐敏、速敏和各种程度碱敏,明晰了该稠油油区敏感性的主要影响因素,为指导后期开发过程中油层保护提供了依据。
Wangzhuang oilfield consists of sensitive heavy oil reservoirs with hundred-million-ton reserves, but extensive experimental research on potential sensitivity mechanism is still lacked. In this paper, taking Zheng 408 block in Wangzhuang oilfield as a study case, with experimental methods of composition analysis and fluid flow test, physicochemical characteristics( clay composition, microscopic characteristics and diagenesis) and change rules of heavy oil reservoirs were analyzed. The results show that the study area is apparently water sensitive, constant velocity sensitive, acid sensitive, salt sensitive and alkali sensitive. Major control factors of reservoir sensitivity have been clarified, which can provide basis for reservoir protection in the late development stage.
