【摘要】：如何高效地開發(fā)儲(chǔ)量豐富的稠油資源,一直是油氣開采領(lǐng)域的一大課題,對(duì)于稠油油藏進(jìn)行精細(xì)地質(zhì)建模和數(shù)值模擬顯得尤為重要,其模擬結(jié)果過(guò)對(duì)稠油油藏的開發(fā)調(diào)整設(shè)計(jì)具有指導(dǎo)意義。坨7塊東一段稠油油藏屬于勝利油田,油藏邊、底水水體很大,地質(zhì)情況復(fù)雜,開發(fā)難度較大。以該區(qū)塊為研究對(duì)象,分析了其地質(zhì)狀況,回顧了其開發(fā)歷程,歸納了地質(zhì)特征和開發(fā)特征;分析了稠油在多孔介質(zhì)中的滲流機(jī)理、考慮熱傳遞的滲流微分方程,利用數(shù)值方法進(jìn)行求解。在分析研究區(qū)塊地質(zhì)特征的基礎(chǔ)上,利用靜態(tài)資料建立了區(qū)塊的三維地質(zhì)模型,進(jìn)一步描述了區(qū)塊的油水分布、物性參數(shù)、斷層走向等特征。在地質(zhì)模型的基礎(chǔ)上進(jìn)行了數(shù)值模擬研究,建立了區(qū)塊靜態(tài)和動(dòng)態(tài)數(shù)據(jù)流模型,擬合了區(qū)塊近20年的生產(chǎn)歷史,主要包括地質(zhì)儲(chǔ)量以及產(chǎn)油量、產(chǎn)液量、含水率等主要開發(fā)指標(biāo),對(duì)擬合結(jié)果進(jìn)行了評(píng)價(jià)。模型建立精度較高,利用此模型對(duì)設(shè)計(jì)的開發(fā)調(diào)整方案進(jìn)行預(yù)測(cè),預(yù)測(cè)結(jié)果可以進(jìn)一步指導(dǎo)區(qū)塊的開發(fā)。
[Abstract]:How to develop rich reserves of heavy oil resources efficiently has been a major topic in the field of oil and gas production. It is particularly important to carry out fine geological modeling and numerical simulation for heavy oil reservoirs. The simulation results have guiding significance for the development adjustment and design of heavy oil reservoir. The heavy oil reservoir in the east section of Tuo7 block belongs to Shengli Oilfield. The reservoir edge and bottom water are very large, the geological situation is complex, and the development is difficult. This paper analyzes its geological condition, reviews its development course, induces geological characteristics and development characteristics, analyzes the seepage mechanism of heavy oil in porous media, and gives a differential equation of seepage considering heat transfer. Based on the analysis and study of the geological characteristics of the block, the three-dimensional geological model of the block is established by using static data, and the distribution of oil and water and the physical parameters of the block are further described. Based on the geological model, the static and dynamic data flow models of the blocks are established, and the production history of the blocks in the past 20 years is fitted, which mainly includes geological reserves, oil production, liquid production, etc. The fitting results are evaluated by the main development indexes such as water cut. The model has a high precision. The model can be used to predict the design development adjustment scheme, and the prediction result can further guide the development of the block.
