Abstract: The basic and public welfare oil and gas geological survey is the field just started by China Geological Survey of the Ministry of Natural Resources.As an indispensable part of the oil and gas geological survey, experimental testing is directly related to the quality and achievements of oil and gas geological work.A set of scientific budget standards for oil and gas geological experiment test is helpful to standardize the budget management of oil and gas projects and reasonably match the financial funds.Starting from the connotation and characteristics of oil and gas geological experiment test, this paper determines the development idea of budget standard, and then introduces the whole process of budget standard development in detail.On the basis of combing the work flow, comparing the technical standards and building the project framework, taking the vitrinite reflectance in hydrocarbon source rock analysis as an example, this paper introduces the cost quota calculation method to calculate the theoretical value of the budget standard, and finally obtains the recommended value of the budget standard through comprehensive comparative analysis.The preparation of the budget standard of oil and gas geological experiment test fills in the blank of the budget standard of oil and gas experiment test in the budget of public welfare oil and gas geological survey, lays the foundation for perfecting the budget standard system of geological survey project, and provides ideas for related laboratories to manage the cost according to quota.
