摘要:
涩北气田是柴达木盆地典型的多层疏松砂岩气藏,具有岩性疏松、层多且薄等特征,气藏储集层从浅至深多达近百个。气田在生产过程中为了提高储量动用程度,实现经济高效开发,采用多层合采方式生产。针对多层合采可能产生的层间干扰、储量动用不均衡等问题,提出多层合采的物理模拟实验方法,并结合数值模拟研究探讨了多层合采时气藏储量动用程度的主要影响因素,系统分析了不同物性和地层压力条件下多层合采开发动态特征。在此基础上,研究多层合采有利条件,以渗透率倍比和压力倍比为评价参数建立判断图版,可对不同气层物性和地层压力条件进行初步判断,评价合采干扰程度,为多层气藏优化射孔组合提供依据。
Abstract:
Sebei gas field in Qaidam basin is a typical sandstone gas reservoir with multiple thin layers and loose sands. There are nearly 100 reservoirs from shallow to deep in the gas field. In order to realize efficient development and to improve reserves producing degree, multi-layer commingled production technology is applied in the gas field. In terms of the problems like interference between layers and unbalanced reserves producing resulted from the commingled production, a physical simulation method is proposed for the commingled production in this paper. Combined with numerical simulation, the main factors influencing the reserves producing degree of the gas reservoir during commingled production are discussed and the production performance under different formation pressures and different physical properties are systematically analyzed. Based on which, the favorable conditions for the commingled production are studied and a series of charts is established by taking permeability multiple ratio and pressure multiple ratio as evaluation parameters, which can be used to judge physical property and formation pressure of different gas zones, then to evaluate the interference degree of the commingled production and finally to provide a basis for the perforation combination optimization in the multi-layered gas reservoirs
