The Study Of Cost Control About Oil-gas Exploration Project

With the gradual reduction of oil resources, the overall level of the exploration unceasingly deepened. Whether in the new or in the old area, the type of oil and gas reservoirs becomes increasingly complex, the difficulty of exploration project work is rapidly increasing, and the construction costs are also showing an upward trend. Enterprises are facing increasingly serious internal and external environment, competitive pressure from domestic and international on the industry is also growing. Faced with such fierce competition, to survive and develop, oil exploration enterprise must strengthen costs management and take various measures to reduce costs. Therefore, to study oil and gas exploration project cost control and to further standardize and improve the oil and gas exploration project cost control system are of great theoretical and practical significance. At present, Chinese scholars studying on oil and gas exploration project cost control is less, having not formed a certain theoretical system and the frame. All gas enterprise cost control data also inconvenience to outside which makes many scholars lack of important realistic basis to launch concrete theoretical research and practical application.Based on the management and petroleum engineering related theory, cost control as a research focus, we deeply analyzed the problem of oil and gas exploration project cost control in China. Firstly, on the basis of the analysis of the present cost control situation that the Chinese petroleum enterprises are in, we analyzed the characteristics of the oil and gas exploration project, and then analyzed the oil and gas exploration project cost constitution. In the exploration cost, drilling engineering cost, cementing project cost and record logging costs occupy a great proportion. So these three costs are the key of an enterprise'cost control and cost management, and the control of drilling engineering cost is the most important. Secondly, expounded the content and principle of the oil and gas exploration project cost control, introduced the current project cost control theory, such as homework cost theory, strategic cost theory, target cost theory and responsibility cost theory, and analyzes their advantages. Finally, expounded the cost control techniques, mainly introduced the earned value analysis, value engineering method and the fixed added. Second, through the comparison and analysis of the present situation of the domestic and international oil and gas exploration project cost control, put forward the problem of the domestic oil and gas exploration project cost control, and the corresponding countermeasures is analyzed; Third, the exploration cost control is in overall, deep analysis, the implementation of the cost control is engaged in before, during, and after three stages. We constructed the grey cost forecast model and the preparation of cost plan, and the exploration project cost is monitored and controlled by using the modified earned value method and value engineering. On this basis, based on the principles of cost control, we discussed the influence of oil and gas exploration project cost changes, formulated cost control measures and checking methods. All of these will provides the basis of the future cost control.
