To braided stream deposit, the fluvial sand body is distribute largely and continuously, so the heterogeneity is poor relatively, the relation of injection and production is better in the case of rare wells, about all wells have come on water, only in some thin sandbodys or bad physical layers there is some low flooded strata
對辮狀河砂體，平面上大面積連續分佈，在平面及層內非均質性弱，在較稀的井網下注采關系就較完善，目前平面上幾乎所有井點都已水淹，只有局部由於砂體厚度變薄，物性相對變差而存在一些低水淹部位。 -
To meander channel, because the channel continuously moved, form duplicate fluvial sand bodies largely, and there are many area of non sandbodies or in fluvial sandbodies, there are some abandoned channel, all make the continuous of sandbodies poor upper the meander channel sandbodies, so remained oil is mainly distributed in sandbodies in fluvial channel, abandoned channel and non sandbodies area nearby
對曲流河砂體，由於平面上曲流河反復遷移和改造，以側蝕和側積方式形成了面積廣闊的復合曲流河砂體，內部發育有許多尖滅區及河間砂體，邊部及內還存在一定數量的廢棄河道，從而使曲流河上半部側向連通性變差，這類砂體中剩餘油主要分佈於河間砂、廢棄河道部位及尖滅區附近。 -
According to the idea of analytical hierarchy process, using structure element analytical method combining outcrop studies, for anatomizing in - layer short lap, to study in detail shengli oil field fluvial facies sand body internal building structure, the complete set reservoir bed can be divided in to single sand bed at highly asymmetrical longitudinal direction and described to microfacies and single sand body at flat
摘要以層次分析思想為指導，應用結構要素分析法，結合露頭研究，解剖層內薄夾層並對砂體內部建築結構進行詳細研究，認為這樣就可以預測性地描繪出勝利油區河流相單砂體的幾何形態、連通性、以及儲層非均質性，準確判斷出砂體的成因類型，揭示了砂體內部建築結構特徵。 -
Regarding pi1 - 2 oil bearing group in the polymer flooding well pattern in the north part of the north section in lamodian oil field, as the target pay zone, this paper has firstly drawn the sedimentary microfacies maps of each time unit by means of the principle of architecture - element analysis and correlation method of sand member in fluvial - delta depositional system. lt gives a sound geological foundation for classification of plane flow unit. at the same time, this paper has classified vertical flow unit
首先，本文以喇嘛甸油田北北塊聚合物驅井網葡i1 - 2砂巖組為研究目的層，應用儲層建築結構解剖的知識和河流-三角洲相油層對比方法，繪制了各沉積單元的沉積相帶圖，為平面流動單元的劃分提供了地質基礎，同時，劃分了垂向流動單元。 -
The reservoir is sand of silurian and jurassic especially of delta and distributary fluvial facies sand. the growth of well reservoir sand is the key fector for gas reservoir to form in this area. by the small porosity of silurian compact sand, the position where comparative homogeneous sand growth with little mud or fracture concentrated is the location for gas to enrich
該區儲層為中上奧陶統、志留系、侏羅系和白堊系砂巖，但以侏羅系的三角洲和扇三角洲相水下分流河道砂體、濱湖相灘壩砂體和志留系濱岸砂巖為主要目的層。 -
Pi formation is combination of thick sand body, because the sediment mode of reservoir in changyuan of daqing is mainly combined of great leaf delta and partly fluvial facies, about 500m thick, combined of 130 little sand or mud layers, which is typical heterogeneity reservoir, the reservoir ' s character is greatly distribute, high permeate and serious heterogeneity
Pi油層組是厚油層組合，由於大慶長垣儲層的沉積模式以大型葉狀三角洲及部分河流相為主，總厚度500多米，由130多個小砂層和泥巖交互而成，是一套典型的非均質砂巖儲層，該儲層具有分佈廣、厚度大、滲透率高和層內非均質性嚴重等特點。
