摘要

边底水油藏开发过程中由于边底水侵入导致垂向矛盾与平面矛盾。氮气泡沫驱因具有气源广泛、价廉经济等优点，是目前泡沫驱中矿场应用最普遍的一种。将氮气泡沫注入底水锥进的油井可发挥明显的压锥效应。塔河油田AT2井区注入水波及体积小，水驱效率低，为改善塔河油田AT2井区三叠系上油组开发效果，利用油藏数值模拟技术开展了氮气泡沫驱可行性研究。

Abstract

In the development of edge and bottom water reservoirs, edge and bottom water intrusions always lead to vertical and plane contradictions. Nitrogen foam flooding, with the advantages of abundant gas source and low cost, is now the most common kind of foam flooding in field applications. Nitrogen foam injection to the oil wells with coned bottom water plays an obvious coning control effect. The injected water ripple of AT2 well block in the Tahe oilfield is small in size, and the water flooding efficiency is low. We used reservoir numerical simulation technology to carry out a feasibility study on nitrogen foam flooding to improve the development effect of the Triassic Yangchang oil group in AT2 well block in the Tahe oilfield.
