UTCHEM是美国Texas大学编制的化学驱软件，此软件的程序框架和机理描
述都很先进。UTCHEM是Texas大学的教学软件，而且由于受到多家机构和部门
的支持，所以UTCHEM考虑的物理化学因素很多，方程比较复杂。这些因素造
就了UTCHEM不能作为很好的商业化学驱数值模拟软件，特别是限制了它在实
际油田的应用。
UTCHEM是一套三维多相综合化学驱软件。UTCHEM对以前
的版本进行了改进，使它能模拟碱驱、聚合物驱、表面活性剂驱、生物驱、泡
沫驱、各种二元复合驱、三元复合驱等多种三次采油方式。在UTCHEM
中，有多种坐标和数值弥散控制方式选择。另外，UTCHEM中还有双重介质选
项，以支持复杂油藏的化学驱数值模拟(UTCHEM is a chemical drive software developed by Texas University in the United States. Its program framework and mechanism are described

Narration is very advanced. UTCHEM is the teaching software of Texas University, and it is widely used in many institutions and departments

Therefore, UTCHEM considers many physical and chemical factors, and the equation is relatively complex.)
