【摘要】 井网密度是油藏开发中的一个重要参数。本文首先对姬塬油田的储层状况、储层的敏感性及开发现状进行了分析;其次依据低渗透砂岩油田的注水开发原则,结合井网适应性分析,发现菱形反九点井网能够减缓角井水淹速度、延长角井水淹时间,提高了侧向油井受效程度。因此在开发初期采用井网密度合理的菱形反九点井网具有较好的效果。更多还原

【Abstract】 Well pattern density is an important parameter in reservoir exploration.This article describes the reservoir conditions,sensitivity and the development status of Jiyuan Oilfield;it is found that rhombic inverted nine-spot well pattern can slow flooding velocity and prolong flooding time of corner wells to improve the extent of water-floodability of the lateral oil wells based on the principle of water flooding in low permeability sandstone oilfield and combined with the analysis of well pattern adaptability.Therefore,rhombic inverted nine-spot well pattern with reasonable well pattern density has received good results in early development.更多还原
