沉积单元 meaning in Chinese
sedimentation unit
Examples
- In order to understand the remaining oil distribution , and provide evidence for numerical simulation of polymer flooding and comprehensive adjustment , a study on the numerical simulation on the water flooding of pu 1 - 2in western south central block is performed
模拟结果表明，剩余油饱和度分布不均匀，西部过渡带和注采系统不完善的断层附近含油饱和度比较高，葡1油层动用状况较差；南中块西部葡2 (下标2 )和葡2 (下标3 )沉积单元发育较好，动用程度较大，最终采收率可达39 . 6 % ~ 43 . 5 % ，而葡1单元则相对较差，最终采收率只达到28 . 1 % 。 - 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块聚合物驱井网葡i1 - 2砂岩组为研究目的层，应用储层建筑结构解剖的知识和河流-三角洲相油层对比方法，绘制了各沉积单元的沉积相带图，为平面流动单元的划分提供了地质基础，同时，划分了垂向流动单元。 - The cross well seismic technology have been applied to ignite and receive inside the well , therefore , it overcame the effects of low weathering layers and increased the resolution by the scale of 10 - 100 times . this technique is capable of delineate the minimum sedimentary unit of the oil - bearing body and resolve the issues like : reservoir interconnection , dynamic monitoring and micro - structural description etc . in addition , it also provides the fine geological model for reservoir modeling and scientific evidence for the oilfield development plan designing
井间地震技术由于是在井中激发、井中接收，从而克服了地表低速带的影响，具有比地面地震高10 - 100倍的分辨率，能够达到分辨最小沉积单元油砂体的能力，因此该技术能够解决储层连通、动态监测、微构造描述等问题，并为油藏建模提供精细的地质模型，从而为开发方案的编制提供科学的依据。 - According to the former research results , by the method of reservoir correlation , that is , by combining sedimentary cycle correlation , hierarchical control and discriminating different sedimentary facies association , the - type oil reservoir in the research target was divided 28 sedimentary units and sedimentary microfacies mode of - type oil reservoir was built . in the light of sedimentary development characteristics , - type oil reservoir was divided into 5 sorts again
根据前人的研究成果，利用“旋回对比，分级控制，不同相带区别对待”油层对比方法，将研究区二类油层划分为28个沉积单元，建立了二类油层沉积微相模式，按沉积发育特征，将研究区二类油层分为5种类型。
