摘要
中扬子西部志留系具备深盆气形成的3个基本地质条件,并在石柱复向斜建深1井志留系钻探中已发现深盆气藏。为有效勘探开发中扬子西部的深盆气资源,需采取的主要对策是:①深化志留系深盆气成藏地质条件和成藏机制的研究;②建立和完善针对志留系薄层致密砂岩气层的横向预测技术;③钻探中采用保护气层的欠平衡钻井和防污染措施,开发上重点发展分层压裂、多层合采和低成本的开发技术。
The basic three geological conditions of forming deep basin gas reservoirs exist in Silurian in the west of the Mid-Yangtze Area, and a deep-basin gas field has been discovered in drilling Silurian to Jianshen 1 Well in Shizhu Synclinorium. In order to effectively explore and develop the deep-basin gas reservoirs in the west of Mid-Yangtze, the main countermeasures adopted necessarily are as follows ：（1）deeply investigating the geological conditions and reservoir forming mechanism of deep-basin gas;（2）establishing and improving the lateral prediction techniques for thin tight sandstone gas reservoirs; （3）adopting under-balance drilling and anti-pollution techniques to protect gas reservoirs, emphatically developing separate-layer fracturing, multi-layered production and low cost techniques.
