摘要
简述了鄂尔多斯盆地东缘深部煤层气勘探认识.分析研究了深部煤层气的富集规律,认为广覆式的厚煤层储集为生气有利条件,温度、应力、含气性成为富集的主控地质因素;致密顶底板的封存形成深部"箱式"成藏条件,正向微构造是产量高的主控因素.阐述了地质物探一体化水平井导向技术、深部煤层大规模体积压裂技术、精细排采管控技术三项开发对策,对深部煤层气的高效开发具有重要意义.
Abstract
The exploration of CBM in the deep eastern margin of Ordos Basin is briefly described.The enrichment law of deep coalbed methane is analyzed and studied,which believes that the thick coalbed reservoir is a favorable condition for life,and temperature,stress and gas content are the main control geological factors;the enrichment of dense top plate forms the deep"box"accumulation condition,and the forward microstructure is the main control factor with high yield.This paper expounds the development countermeasures of integrated horizontal well guide technology,large-scale volume fracturing technology and fine extraction control technology,which are of great significance to the efficient development of deep coalbed methane.
