【摘要】：位于大慶市的喇嘛甸油田地下儲氣庫是我國投產(chǎn)最早的地下儲氣庫。該儲氣庫是基于其層狀砂巖油田的氣頂進行建設(shè)的。喇嘛甸油田具有獨特的構(gòu)造形式。是一個受構(gòu)造控制的短袖式的背斜氣頂油藏,他的主要儲集層屬于河流三角洲沉積形式。其砂體形式呈現(xiàn)樹枝狀或帶狀分布。本文對該油田的氣層地質(zhì)相關(guān)特征進行分析并對地下儲氣庫基本概況運用進行了一系列專業(yè)分析。運用PETREL軟件和ECLIPSE軟件對喇嘛甸北塊氣層儲層建立了三維構(gòu)造模型及儲層屬性模型。通過數(shù)據(jù)分析擬合研究了油井與氣井的相互影響及動態(tài)關(guān)系。確定了壓差界限之外還對儲氣庫的最大調(diào)峰能力進行了計算。針對注懫氣井的地層系數(shù)和構(gòu)造位置,確定了單井配注(懫)氣量占儲氣庫總配注(采)氣量的百分比,同時按此百分比實施配注(采),利用數(shù)值模擬技術(shù),優(yōu)選出在節(jié)點分析方法確定的儲氣庫合理日注(采)氣量范圍內(nèi)的最佳配注(采)方案;最后提出了儲氣庫多周期注采氣運行方案,并對產(chǎn)水、產(chǎn)油等現(xiàn)象進行了分析。
[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.
