欢127莲花油藏剩余油分布规律及挖潜对策研究

STUDY OF HUAN 127 LOTUS REMAINING OIL DISTRIBUTION AND POTENTIAL COUNTERMEASURES

欢127莲花油藏已处于稠油蒸汽吞吐开发后期,区块接近废弃边缘。2005年以来,遵循油田后期开发必须"精细小层研究"的原则,对区块进行了精细油藏地质研究;采用油藏工程方法,对小层剩余油分布规律进行了量化描述,并提出了大位移侧钻、利用水平井开发等改善开发效果的方法,取得了好的效果。

Huan 127 Lotus heavy oil reservoir has been the development later period of steam stimulation,the block close to the edge of the abandoned.Since 2005,based on the principle of oilfield late development,the detailed reservoir geological studies were carried out.The distribution of small layer remaining oil was described by using reservoir engineering methods,and the methods of improving development effect were put forward by sidetracking extended reach wellbore and horizontal well,and good results had been achieved.
