如何对深层裂缝性火山岩油藏进行项目经济评价是当前经济评价工作中的一个难题。通过测算石西油田开发工程投资和方案采油成本.特别是将石西油田深层裂缝性火山岩油藏开发建设工程各项定额的制定,以及投资、生产成本费用的测算,作为经济评价工作的重点进行了研究。依据石西油田特殊的地质状况、地理环境和开发实际情况创立了一整套深层火山岩油藏技术经济评价方法,并建立了经济可采储量及建百万吨产能极限投资的计算方法。该方法在石西油田应用后获得成功,此方法也适用于其它油田的经济评价。
How to carry out project economic evaluation of deep-seated volcanic reservoirs is a difficult problem in the current economic evaluation. Through the calculation of Shixi oilfield development project investment and cost of oil extraction.Especially the development of deep fractured volcanic reservoirs in Shixi oilfield development and construction of the quotas, as well as investment, production cost estimates, as the focus of economic evaluation work Study. Based on the special geological conditions, geographical environment and actual conditions of development in Shixi Oilfield, a set of technical and economic evaluation methods for deep volcanic reservoirs were established, and the calculation method of economically recoverable reserves and the investment of one million tons of production capacity limit was established. The method is successful after its application in Shixi Oilfield. This method is also applicable to the economic evaluation of other oilfields.
