The Research Of Resources Development Potential Evaluation In Chuankou Oilfield

Chuankou oilfield is an old oilfield of Yan chang company, Chang 6 is the main production layer in Triassic Yanchang Formation. In 1992, it has put into production, in 2002, its annual oil production was more than 200000 tons, and in 2004, annual oil production exceeded 500000 tons, at present, it still maintained at 450000 tons. Due to consecutive years of rapid real estate development, the stable oil production is getting more and more difficult, to maintain stable production has become an important task in Chuankou oilfield. Therefore, development production trend and economic recoverable reserves under the conditions of science and the technology in oilfield of different development block, predict required new production and recoverable reserves in order to maintain the stable oil production, and analysis and evaluation the measures of increased new reserves or the feasibility of increasing oil production, promot the recoverable reserves, estimation of corresponding workload required urgent. This work, for the sustainable development of the oil field, has important practical significance.Based on the geological characteristics of Chuankou oilfield, calculate the reserves has been submitted to proved reserves, clear the distribution of the proven reserves has been utilized in different layers and proven reserves unused. According to the reserves, development mode and production of crude oil composition, based on the development unit forecast water yield change trend of each unit, calculate the production decline rule; calculate the economic recoverable reserves in each development unit under the conditions at present technology. For the failure type development unit, compare effect different layers and different measures on increasing production, put forward constructive measures, evaluate the increase production and recoverable reserves potential; compared with the development effect of water flooding development and failure type of comparison, evaluate the potential of water flooding increase the yield and recoverable reserves. According to the development zone production rule, combined with the analysis geological conditions differences in undeveloped area and developed zone, evaluate the recoverable reserves and production potential undeveloped new areas.
