华庆油田白257区长6油藏井网加密技术研究

Research on Well Pattern Infilling Technology of Chang 6 Reservoir in Bai 257 Area of Huaqing Oilfield

针对白257区长6油藏所面临的综合含水高、地质储量采出程度低、油井产能较低,低产井比例偏大,产量与油层发育不匹配等开发矛盾,在地质特征及开发现状研究的基础上,以关50-197和关44-203两个典型井组为例,结合油藏工程和地质研究的认识,利用数模方法进行井网加密方案的设计与优选,最终确定关50-197井组CASE 2与关44-203井组CASE 3为最优方案。

Aiming at the contradictions in the comprehensive development of Chang 6 reservoir in Bai 257 area, such as high water cut, low recovery of geological reserves, low productivity of wells, and so on, based on the study of geological features and development status, taking two typical wells of Guan 50-197 and Guan 44-203 as examples, the well pattern infilling schemes were designed and optimized by numerical simulation method, the optimal solutions were determined as follows： CASE 2 scheme for the 50-197 well group and CASE 3 scheme for the 44-203 well group.
