摘要

针对艾湖油田玛18井区低渗透砂砾岩油藏直井压裂单井可采储量低、经济效益差的问题,通过油藏数值模拟法、油藏工程方法、经济极限法和矿场试验法对多级压裂水平井参数设计和产能预测开展研究。结果表明:玛18井区“甜点”深度为3 876~3 881 m,水平井走向应为南北向,推荐水平井水平段长度为1 200~1 400 m,井间距为500 m,裂缝半长为150 m,裂缝间距为50 m。采用优化参数设计6口多级压裂水平井,第1 a平均日产油为29.0 t/d,符合产能预测数据(25.0~33.0 t/d)。该研究建立了砂砾岩储层含油饱和度预测方法,并形成砂砾岩油藏多级压裂水平井参数设计和产能预测方法,可为同类油藏的开发提供借鉴。

Abstract

In response to the problems of low recoverable reserves and poor commercial benefits of single well with vertical well fracturing in low-permeability conglomerate reservoir in Well Block Ma18, Aihu Oilfield, the parameter design and productivity prediction of multi-stage fractured horizontal wells were investigated by numerical reservoir simulation, reservoir engineering method, economic limit method and mine field test method. The results indicated that the "sweet spot" depth in Well Block Ma18 was 3 876 to 3 881 m, the horizontal well strike should be in north-south direction, the recommended length of horizontal interval in horizontal well was 1 200 to 1 400 m, the well spacing was 500 m, the fracture half-length was 150 m, and the fracture spacing was 50 m. Six multi-stage fractured horizontal wells were designed with optimized parameters, achieving an average daily oil production of 29.0 t/d in the first year, which was consistent with the predicted production of 25.0 to 33.0 t/d. This study developed an oil saturation prediction method for conglomerate reservoir, and developed a method of parameter design and productivity prediction for multi-stage fractured horizontal wells in conglomerate reservoir, providing a reference for similar reservoirs.

Key words： low-permeability conglomerate reservoir; multi-stage fractured horizontal well; productivity prediction; Aihu Oilfield; Well Block Ma18
