热采工艺是世界上各大油田用来开来高渗透率矿藏中重质油或沥青的主要工艺之一。而水平并具有改善波及系数。扩大可采储量、增强度汽能力、减少油田开发所用井数等优点，所以它在热采工艺中的应开越来越受到人们的关注。水平并可用做注汽井和采油井，本文论述了水平分在热采工艺中的应用及其优缺点，主要讨论了水平井在蒸汽吞吐、蒸汽驱、蒸汽重力驱几种工艺中的应用。同时也回顾了这种技术在美国中西部和加拿大的重质油层和沥青储层中的现场应用，从而说明其经济上的可行性。
Thermal recovery technology is one of the major processes used by major oil fields in the world to open heavy oil or bitumen in high-permeability deposits. The level and has improved the sweep coefficient. Expand recoverable reserves, enhance the degree of steam capacity, reduce the number of wells used in oilfield development and other advantages, so it should be more and more people’s attention in the thermal recovery process. Level and can be used as steam injection wells and oil production wells. This paper discusses the application of horizontal distribution in thermal recovery process and its advantages and disadvantages. It mainly discusses the application of horizontal wells in several processes such as steam stimulation, steam flooding and steam gravity flooding. It also reviews the field application of this technology in heavy oil and bitumen reservoirs in the Midwest and Canada, demonstrating its economic viability.
