影响水平井开发裂缝性潜山油藏的主要因素分析

Analysis of the Main Factors on Impacting Horizontal Development in Buried Hill Fractured Reservoir

裂缝性油藏一般埋藏深,钻井投资高,裂缝发育区域、方位和规模的认识又难以定量,带来了该类油藏水平井部署风险。然而,该类油藏裂缝发育、渗透率较高、油层厚度大、连通性好,采用水平井开发能够达到比较高的单井产量。本文运用数理统计学分析方法,结合油藏数值模拟计算,研究了裂缝性潜山油藏的地层参数对水平井开发效果的影响,找出了影响水平井开发效果的主要因素。这对于指导裂缝性油藏有效开发具有重要的理论价值。

Fractured reservoir is generally buried deep ,drilling investment is high, Crack development regional、position and scale are difficultly quantified, brought horizontal wells deployment risks of such reservoir. But crack development in this reservoir.higher penetration rate.thickness of this reservoir and good connectivity, horizontal well development can be achieved relatively high yield of single well. This paper uses mathematical statistical analysis method and numerical simulation, formation parameters in buried fractured hill reservoir of horizontal development of the effects is studied, identified the main factors, this has great theoretical value on guiding the effective development of fractured reservoir.
