【摘要】：隨著近年來華北油田勘探開發(fā)程度的加深,一些以三角洲前緣為沉積背景的砂泥巖薄互層正逐漸成為儲量接替的主要儲層。這些儲層多是非均質(zhì)性強、分布不規(guī)律的巖性儲層,致使確定儲層邊界、搞清儲層在橫向和縱向上的變化規(guī)律及分布特點變得非常困難,因此高精度儲層預(yù)測技術(shù)變得尤為重要本文詳細(xì)分析了制約高精度儲層預(yù)測技術(shù)的關(guān)鍵因素,并且從問題入手,應(yīng)用地震、地質(zhì)等資料并結(jié)合相關(guān)理論,針對常規(guī)的確定性反演分辨力低,難以識別薄砂體的問題,充分開發(fā)有利儲層的高精度識別的反演方法。本文研究了目前常用的地質(zhì)統(tǒng)計學(xué)反演方法、提頻拓頻方法、約束稀疏脈沖反演方法等高精度儲層預(yù)測方法,并在饒陽凹陷、霸縣凹陷等多個地區(qū)進(jìn)行了詳細(xì)的應(yīng)用。通過效果的對比分析,有針對性的總結(jié)了適用于不同儲層類型的高精度儲層反演流程。本文通過在華北油田多個地區(qū)的儲層預(yù)測應(yīng)用研究,提出了以巖石地球物理分析為核心的,適用于砂泥巖薄互層等多種儲層類型的高精度預(yù)測方法,提高了預(yù)測結(jié)果的分辨率,并且能夠更加精確地描述儲層細(xì)微的變化。
[Abstract]:With the deepening of exploration and development of Huabei Oilfield in recent years, some sand and mudstone thin interbeds with delta front as the sedimentary background are gradually becoming the main reservoir of reserves replacement. Most of these reservoirs are lithologic reservoirs with strong heterogeneity and irregular distribution, which makes it very difficult to determine reservoir boundaries and to find out the variation laws and distribution characteristics of reservoirs in horizontal and vertical directions. Therefore, the high-precision reservoir prediction technology becomes particularly important. This paper analyzes the key factors restricting the high-precision reservoir prediction technology in detail, and starts with the problems, applies seismic, geological and other data and combines the relevant theories. In view of the low resolution of conventional deterministic inversion, it is difficult to identify thin sand bodies, and fully develop the inversion method with high accuracy for favorable reservoir identification. In this paper, the methods of high-precision reservoir prediction, such as geostatistical inversion method, frequency-increasing method, constrained sparse pulse inversion method and so on, are studied and applied in many areas such as Raoyang Sag, Baxian Sag and so on. Through the comparison and analysis of the effect, the flow of high precision reservoir inversion suitable for different reservoir types is summarized. Based on the application of reservoir prediction in many areas of North China Oilfield, this paper presents a high precision prediction method based on rock geophysical analysis, which is suitable for various reservoir types, such as sand and mudstone thin interbeds, and improves the resolution of the prediction results. And can more accurately describe the subtle changes in the reservoir.
