榆林气田具有多层含气特征,主力储层山2段为辫状河三角洲沉积体系,砂体具有大面积分布特征,为一大型岩性圈闭气藏。有效储层具有明显的“低孔、低渗”特征,开发难度较大,勘探初期,开发评价工作提前介入,通过勘探开发一体化,形成了一套行之有效的储层精细描述和快速上产等特色技术,保证了气田快速稳步上产。该技术对开发同类型气田具有重要的借鉴意义。 The Yulin gas field is characterized by multi-layer gas. The main reservoirs in Block 2 are braided river delta sedimentary systems, and the sand bodies have a large-area distribution and are large-scale lithologic trap gas reservoirs. Effective reservoirs have obvious features of “low porosity and low permeability”, and they are difficult to develop. In the early stage of exploration, development and evaluation work is intervened in advance. Through the integration of exploration and development, a set of effective reservoir description and Quickly on the production and other special technologies to ensure that the gas field quickly and steadily on the production. This technology has important reference for the development of the same type of gas field.
