Shandong Hekou Economic Development Zone has seized the strategic opportunity of developing the "Efficient Ecological Economic Zone of the Yellow River Delta" and the "Blue Zone of Shandong Peninsula" to vigorously develop the petroleum equipment industry. Up till now, industrial clustering has been achieved. In the park, a large number of oil equipment manufacturing enterprises with strong innovation ability, large investment scale, and strong driving force have gathered such as Jingcheng, Jinyu, Jinkai and Haixin, which can produce seamless steel tubes, oil and gas tubing, casing, and drill rods. Various new products such as pipelines, boiler tubes, and boilers have realized the industrial chain of “overground and underground†coverage for drilling and production. On the basis of the development of oil equipment manufacturing industries such as oil and steel pipes, instrumentation, drilling rigs and drilling rigs, the park also actively cultivates service industries such as trade and logistics, technology research and development, and financial information to promote the rapid rise of advantageous industries.
