【摘要】：二類油層的劃分標(biāo)準(zhǔn)為滲透率介于80~600?10?3μm2,有效厚度介于1~2.5m之間,單元間滲透率級(jí)差在1.4~3.5之間。二類油層的物性與主力油層相比存在明顯差異,因此在聚合物驅(qū)跟蹤調(diào)整方法的選擇上也應(yīng)有別于主力油層,并且其開發(fā)效果的影響因素也與主力油層不同,需建立一套新的二類油層聚驅(qū)全過(guò)程的跟蹤調(diào)整方法。本文通過(guò)統(tǒng)計(jì)分析二類油層實(shí)際區(qū)塊聚合物驅(qū)開發(fā)效果,研究了影響二類油層聚合物驅(qū)開發(fā)效果的動(dòng)靜態(tài)因素,分析了油藏參數(shù)、化學(xué)劑參數(shù)、注入?yún)?shù)及井距對(duì)二類油層聚合物驅(qū)開發(fā)效果的影響。研究了建立二類油層聚合物驅(qū)數(shù)值模擬概念模型的方法,分別建立了二層、三層、五層非均質(zhì)聚合物驅(qū)數(shù)值模擬概念模型,設(shè)計(jì)了不同動(dòng)、靜態(tài)參數(shù)條件下的概念模型方案278個(gè),進(jìn)行了聚合物驅(qū)注入能力研究。分析了二類油層聚合物驅(qū)調(diào)剖、酸化、壓裂在不同時(shí)期、不同的油藏參數(shù)和生產(chǎn)動(dòng)態(tài)參數(shù)條件下平面和縱向的波及規(guī)律,研究了二類油層聚合物驅(qū)調(diào)整措施的選井選層原則,確定了聚合物驅(qū)全過(guò)程不同含水階段不同措施下的開發(fā)效果及技術(shù)界限。
[Abstract]:The classification standard of the second class oil reservoir is that the permeability is between 80 ~ 600? 10? 3 渭 m ~ 2, effective thickness is between 1 ~ 2.5 m, and the permeability difference between units is between 1.4 ~ 3.5. The physical properties of the second type reservoir are obviously different from that of the main reservoir. Therefore, the selection of polymer flooding tracking adjustment methods should also be different from the main reservoir, and its development effect factors are also different from the main reservoir. It is necessary to establish a new method for tracking and adjusting the whole process of polymer flooding in the second class oil reservoir. In this paper, the development effect of polymer flooding in the real block of the second class reservoir is analyzed statistically. The dynamic and static factors affecting the development effect of polymer flooding in the second class reservoir are studied, and the reservoir parameters and chemical agent parameters are analyzed. The effect of injection parameters and well spacing on the development effect of polymer flooding in the second class reservoir. The method of establishing the conceptual model of polymer flooding numerical simulation for the second class reservoir is studied, and the second layer and the third layer are established respectively. Numerical simulation conceptual models of five-layer heterogeneous polymer flooding are designed and 278 conceptual models with different dynamic and static parameters are designed. This paper studies the injection ability of polymer flooding and analyzes the sweep law of plane and longitudinally under the conditions of polymer flooding profile control acidification and fracturing in different periods different reservoir parameters and production performance parameters. The principle of well selection and reservoir selection for the adjustment measures of polymer flooding in the second class oil reservoir is studied, and the development effect and technical limit are determined under different water cut stages and measures in the whole process of polymer flooding.
