对上产新区气藏进行开发评价及开发指标预测是编制气田开发计划及中长期开发规划工作的重要组成部分，接替资源潜力清楚，才能使气田开发工作早期介入，以提高气田开发的经济效益。文章对川东石炭系气藏的控制、预测储量的可靠性及转化率进行了分析，总的来说，四川石油管理局上报的石炭系控制、预测储量普遍比储量计算要求的地质认识程度和计算条件高，其平均转化率分别为９０％和７０％，其次，在新区气藏资料很少的情况下，利用老

DEVELOPMENT EVALUATION OF THE NEW PRODUCTION REGION OF CARBONIFEROUS IN EAST SICHUAN AND ITS DEVELOPMENT IN DEX FORECAST

The development evaluation and development index forecast of the gas reservoir in a new production region are the important component part of drawing up a gas field develop ment plan and a middle- and long-term development pro gramme. Only the replacing resource potential is proved,can the gas field development work be early involved in so as to raise the economic benefit of gas field development. Through analyzing the reliability and conversion rates of the control reserves and prognostic reserves of the gas reservoirs in Carboniferous in East Sichuan,it is concluded that the mean conversion rates of the control reserves and prognostic reserves in Carboniferous report ed by SPA are 90% and 70% respectively, because their geolog ical recognition level and calculation conditions are higher than those demanded by reserve calculation standard generally. Under the condition of lacking of gas reservoir data in a new region, a geological model of gas reservoir classification evaluation was set up through cloosing four geological parameters reflecting the storage and permeability characters of gas reservoir by use of the data on storage, permeability and performance of the gas reser voir in developed region. According to the geological model, the gas reservoirs can be divided into Type Ⅰ gas reservoir with high-permeability and homogeneity; Type Ⅱ gas reservoir with middlepermeability and non-homogeneity; and Type Ⅲ gas reservoir with low-permeability and hard produdng. In light of the correlation of geological characters with the type and devel opment indexes of gas reservoirs in developed region, the classifi cation evaluation and development index forecast of the gas reservoir in new region can be carried out by use of nerve net work method.
