阜新刘家区井田地质构造对煤储层影响及有利区块预测

THE EFFECTS OF GELOLOGIC STRUCTURE ON THE COLA RESERVOIR AND THE PREDICTION OF FAVORABLE TRACTS IN LIUJIAQU MINE FIELD, FUXIN

煤层气开发的有利区块研究重点是构造预测及评价，地质构造一方面决定或改变了煤层气的保存条件，另一方面改善了煤储层特性一本文以平均整旋角（θ）的梯度作为基本特征量，研究了井田构造变形转动场及其破坏规律，对井田煤层气赋存地质条件及开发有利区块进行了初步预测及评价。所得结论为本区煤层气开发布扎提供了科学依据。

In CBM development ,the emphases of favorable tract research are the structaml prediction and evaluation.The geologic structure changes the preservation condition of Cgu in one hand, and improves the properties ofcoal reservoir in other hand. Adopting the gradient of mean rotation angle (θ) as the basic characteristic quanity, therotation field of structural defonnation and its destr-uction fegularity in thene field are studied bythe authars based onthe edic analysis, then the preliminary prediction and evaluation of the geologic conditions of CBM occurrence andthe development of favorable rtacts in the mine field are cwhed out.The obtained conclusbo provide the scienificbasis for the layout of CBM deveipent well in this area.
