摘要:
致密凝析气藏储层物性较差,油气水三相渗流导致气相渗透率较低,该类气藏采收率普遍不高于30%。断层既是油气高产的重要条件,也是水侵的重要通道,搞清楚断层特征与该类气藏开发效果的相关性至关重要。安岳气田须二气藏属于低孔、低渗、有水、凝析气藏,储层储集空间以残余原生孔、粒间粒内溶孔为主,局部裂缝较发育,孔渗关系具双重介质特征,单井控制储量低。利用油藏工程理论、岩心物理模拟实验与数值模拟技术相结合的方法研究分析该气藏断层特征,并将断层分布模式进行分类,研究其与单井控制储量、递减率、累计产量以及流体产出特征的关系,认为:同一断层由于受力不同,其空间产状不一,断层不同部位的井产能悬殊,断层末梢段裂缝更发育,位于断层末稍端的井其测试产量是钻遇断层其他部位井产量的3 倍; 位于须二上亚段为断层模式1,位于须二上亚段+ 下亚段为断层模式2,位于须二上亚段+ 下亚段+ 雷口坡组为断层模式3,井位部署时所布井的断层模式优先考虑顺序依次为模式3、模式1、模式2,并优先选择断层末端进行布井。
Abstract:
The reservoir physical properties of tight condensate gas reservoirs are poorer and their gas permeability is lower due to oil, gas and water flow. The recovery factor of tight condensate gas reservoirs is generally lower than 30%. A Fault is the important condition for the high yield of oil and gas, and also the important pathways for water invasion, so it is crucial to figure out the correlation between the characteristics of faults and the development effectiveness of tight condensate gas reservoirs. The gas reservoir of Xu 2 Member in Anyue Gas Field is a water-bearing condensate gas reservoir of low porosity and low permeability. Its reservoir space is mainly acted by residual primary pores and intergranular and intragranular dissolved pores, and fractures are relatively development locally. Their porosity-permeability relationship presents the feature of dual media. Single-well controlled reserve is less. In this paper, the fault characteristics of tight condensate gas reservoirs were analyzed by using the combined method of reservoir engineering theory, core physical simulation experiment and numerical simulation technology. Then, the distribution patterns of faults were classified and their relationships with single-well controlled reserve, decline rate, cumulative production and fluid production characteristics were studied. It is indicated that as for the same fault, its force is different, so its spatial occurrence is different, and the well productivity at different positions of the fault varies greatly. Fractures are more developed at the end of a fault, so the oil production rate of the well located at the end of a fault is 3 times that of the wells drilling the other parts of the fault. In addition, it is fault pattern I in the Upper Submember of Xu 2, fault pattern 2 in the Upper Submember + Lower Submember of Xu 2 Member and fault pattern 3 in the Upper Submember + Lower Submember of Xu 2 Member + Leikoupo Formation. The priority of fault pattern during well arrangement shall be fault pattern 3, 1 and 2, and the end of a fault is the preferred location for well arrangement.
