The first exploratory well of the Liaohe Oilfield

The first exploratory well of the Liaohe Oilfield is a cultural relic protection unit of Liaoning Province.

The "Liao Yi Well" is the first exploratory well of the Liaohe Oilfield. In the 1960s, the lower Liaohe Plain was crisscrossed with ditches, covered in tidal flats and reeds, sparsely populated, and desolate, earning the name "the Great Wasteland of the South." In February 1964, the sound of exploration blasting from the Second Regional Geological Survey Brigade of the National Ministry of Geology broke the tranquility of this wilderness. They surveyed well locations on the Liaohe Plain, today’s Xihuangjindai Village at Dongfeng Farm in Panjin City, and determined the site for Liao Yi Well. At that time, there were no roads, transportation was inconvenient, and living conditions were extremely harsh. Over a hundred drilling team members from the 3207 Drilling Brigade of the Ministry of Geology and Mineral Resources carried equipment and supplies by hand and shoulder, transporting batches of production materials, erecting the first drilling rig in the wilderness, and officially starting drilling at 23:48 on July 8 of the same year. From midsummer to deep winter, under harsh natural conditions, they played the prelude to oil drilling on the Liaohe Plain.

After more than half a year of arduous work, Liao Yi Well was completed on February 15, 1965, with a depth of 2,720.48 meters. This well established the stratigraphic profile of the upper Tertiary system in the lower Liaohe Plain, confirming the presence of oil and gas resources in the southern part of the eastern depression. The oil and gas exploration of the Liaohe Plain advanced from general survey exploration into a new phase of searching for oil and gas fields.

In November 2003, Liao Yi Well was approved by the Panjin Municipal Government as a municipal-level cultural relic protection unit. In 2006, it was designated as a “Corporate Spirit Education Base” by the group company.

Protected area: Within 90 meters east, 87 meters south, 30 meters west, and 33 meters north of the center of the first exploratory well.

Construction control zone: A Zone II construction control area within 100 meters east, south, and north, and 60 meters west of the protected area.
