I. Introduction The news of the completion of Liaohe Oilfield was announced on January 28, 1980. This oil and gas reserves are very rich, thick reservoirs, reservoir types and more. Some oil wells have a thickness of over 100 meters and produce hundreds of tons of crude oil per day. The quality of crude oil is better, low sulfur, light components and more. At present, the oilfield has an annual production capacity of 5 million tons of crude oil and 1.7 billion cubic meters of natural gas. The Liaohe Basin, where the Liaohe Oilfield is located, is located between Shenyang, Yingkou and Jinzhou with an elongated northerly belt that connects the southwest with Liaodong Bay (Figure 1).
