【摘要】：大港探區(qū)孔店油田館陶組為辮狀河沉積。辮狀河沉積,近物源,儲(chǔ)層較厚,以"砂包泥"為特征,儲(chǔ)層復(fù)雜多變,一般高孔高滲。由于這些特點(diǎn),在以往的研究中通常以構(gòu)造控藏思路為主。然而隨著開(kāi)發(fā)的推進(jìn)及鉆井的增多,多區(qū)存在"高水低油"的油藏關(guān)系矛盾。成藏規(guī)律復(fù)雜,儲(chǔ)層的展布及變化不清。所以非常有必要展開(kāi)儲(chǔ)層的精細(xì)預(yù)測(cè),從而明確井間儲(chǔ)層分布規(guī)律,為巖性油氣藏的研究奠定基礎(chǔ)。本文首先利用地層切片技術(shù)宏觀分析研究區(qū)的沉積背景;然后在模型正演的指導(dǎo)下,應(yīng)用90°相位化技術(shù)、分頻技術(shù)劃分沉積相帶;最后應(yīng)用流體活動(dòng)性屬性預(yù)測(cè)研究區(qū)儲(chǔ)層含油氣性。
[Abstract]:Guantao formation in Kongdian Oilfield of Dagang exploration area is braided river sedimentary, near material source, thick reservoir, characterized by "sand and mud", complex reservoir, high porosity and high permeability. In the past studies, the main idea of reservoir control is structure control. However, with the development of development and the increase of drilling, there is a contradiction of reservoir relationship between "high water and low oil" in many areas, and the law of reservoir formation is complex. The distribution and variation of the reservoir is not clear. So it is very necessary to develop the fine prediction of the reservoir so as to make clear the distribution law of the reservoir between the wells. In this paper, we firstly use stratigraphic slicing technology to macroscopically analyze the sedimentary background of the study area, then, under the guidance of model forward modeling, apply 90 擄phase technique and divide frequency technique to divide sedimentary facies zone. Finally, the oil and gas properties of the reservoir in the study area are predicted by the fluid activity attribute.
