断块油气藏井型井网水平井参数优化Fault Block Reservoir Well Type and Well Pattern Horizontal Well Parameter Optimization

摘要:

本文首先对复杂断块油气藏A区储层特性和地质概况进行分析,然后利用Petrel地质建模软件和Eclipse数值模拟技术软件对油气藏井型井网进行确定,最后对水平井井距、水平井水平段长度进行了优化。研究结果表明:凝析气藏凝析气和油环采用直井进行衰竭式开采,近东西向伴生断层以南油藏采用水平井进行衰竭式开采;平行四边形井网,井距为200 m,最佳水平段长为300 m。所得结论对该区的认识和开发具有重要的指导意义。

Firstly, we analysis the reservoir characteristics and the geological condition in complex fault block condensate oil and gas zone A. Then we use the Petrel software and Eclipse software to determine the well type and well pattern. Finally we optimize the two parameters of horizontal well’s well spacing and horizontal well’s horizontal section length. The results show that the condensate gas and oil ring of condensate gas reservoir fits using vertical well in depletion development. The oil reservoir south of the early east-west associated mining fault fits using horizontal well to develop. The shape of well pattern is a parallelogram, and the well spacing is 200 m, and the horizontal section length is 300 m. The conclusion is of great significance to the realization and development of this zone.
