lateral density variation
解釋
橫向密度變化-
The studies of plane heterogeneity are as follows : the text counts the parameters of the sandlayers " geometric shape of different sedimentous microfacies ; speculates the conditions of lateral communication by sandstone density according to the method brought forward by j. r. l. allen ; gets a group of parameters including the reservoir thickness, porosity and coefficient of permeability by using kriging method according to the data of logging results ; makes certain the direction of coefficient of permeability with variation function by modeling globosity function ; divides the sandlayers into five types by using the method of flowing cell based on three parameters, that is x h, kxh and h / h, and accounts the favorable region. on the base of above - mentioned studies, the text evaluates the heterogeneity of sandlayers and gives the resolutions to these problems to serve the development of the field
Allen ）等人提出的統計方法，用垂向上砂體密度的界限來推測砂體側向連通情況；根據每口井的測井解釋資料，利用克里金插值法對外間進行插值，得到了一組反映儲層特徵在平面上變化的參數，包括儲層厚度分佈、孔隙度以及滲透率，並且成圖；利用變差函數法，通過球狀函數模擬，確定儲層優勢滲透率方向：根據流動單元法，以儲能系數、容積系數以及凈毛厚度比三個參數為依據，通過聚類分析方法進行流動單元劃分，並且按照參數特徵將其分為五類，統計各砂層有利流動單元區塊。
