摘要： 西江23-1油田是一个典型的疏松砂岩底水油藏,针对油藏在整体开发过程中的难题,创新性地采用了中心管完井技术、适度出砂开采技术、储集层保护技术以及提高水平井段质量的钻井等多项技术。克服了钻水平井增斜难度大、开采过程中油层堵塞和底水锥进严重等困难,实现了油田整体开发的成功,并积累了适用于疏松砂岩底水油藏开发的水平井配套技术和开发经验。

Abstract: In consideration of overall development difficulties of Xijiang 23-1 oilfield that is a typical loose sand reservoir with bottom water, many new technologies have been applied, such as pipe base completion, reasonable sand production, reservoir damage prevention and drilling for improving quality of horizontal well interval, etc. These technologies to overcome horizontal drilling buildup difficulty, formation damage and bottom water coning allow the overall development of Xijiang 23-1 oilfield to be finally successful. Accordingly, a series of development technologies and experiences suitable for such a reservoir are accumulated.

Key words: bottom water reservoir, bottom water coning, loose sandstone, reasonable sand production, pipe base, formation damage prevention
