【摘要】:位于大庆市的喇嘛甸油田地下储气库是我国投产最早的地下储气库。该储气库是基于其层状砂岩油田的气顶进行建设的。喇嘛甸油田具有独特的构造形式。是一个受构造控制的短袖式的背斜气顶油藏,他的主要储集层属于河流三角洲沉积形式。其砂体形式呈现树枝状或带状分布。本文对该油田的气层地质相关特征进行分析并对地下储气库基本概况运用进行了一系列专业分析。运用PETREL软件和ECLIPSE软件对喇嘛甸北块气层储层建立了三维构造模型及储层属性模型。通过数据分析拟合研究了油井与气井的相互影响及动态关系。确定了压差界限之外还对储气库的最大调峰能力进行了计算。针对注懫气井的地层系数和构造位置,确定了单井配注(懫)气量占储气库总配注(采)气量的百分比,同时按此百分比实施配注(采),利用数值模拟技术,优选出在节点分析方法确定的储气库合理日注(采)气量范围内的最佳配注(采)方案;最后提出了储气库多周期注采气运行方案,并对产水、产油等现象进行了分析。
[Abstract]:Lamadian Oilfield, located in Daqing City, is the earliest underground gas storage in China.The reservoir is based on the gas cap of the stratified sandstone oil field.Lamadian Oilfield has a unique structural form.It is a structurally controlled short-sleeve anticline gas cap reservoir, and its main reservoir belongs to fluvial delta sedimentary form.The sand body is distributed in dendritic or banded form.In this paper, the related characteristics of gas reservoir geology in the oilfield are analyzed, and a series of professional analyses are made on the basic situation of underground gas storage.Three-dimensional structural model and reservoir attribute model were established by using PETREL software and ECLIPSE software for the reservoir of Lamadian North Block.The interaction and dynamic relationship between oil well and gas well are studied by data analysis and fitting.In addition to the pressure difference limit, the maximum peak shaving capacity of gas storage is calculated.According to the formation coefficient and structural location of gas injection wells, the percentage of single well gas injection ratio to total gas distribution (production) in gas reservoir is determined, and the distribution (production) is carried out according to this percentage, and the numerical simulation technique is used.The optimal injection (production) scheme in the reasonable daily gas injection (production) range determined by the node analysis method is selected, and finally, the operation scheme of multi-period gas injection and production of gas storage is put forward, and the phenomena of water production and oil production are analyzed.
