Abstract: To carry out the construction of internal simulation market system in oil and gas field enterprises is an effective way to address the weak sense of independent operation among employees,low management efficiency,and unsatisfactory operational results. Taking engineering design in oil and gas field enterprises as an example,starting from the simulation market,price system,settlement system,assessment system and other key elements,this paper elaborates the method and path of building the internal simulation market,which has a certain reference role for related enterprises to improve management efficiency and improve the operating efficiency.

Key words: oilfield enterprise, engineering design, internal simulation market, price
