夹层对蒸汽辅助重力泄油的影响
Impacts of Interlayers on SAGD
摘要
Abstract
Blocks with steam assisted gravity flooding (SAGD)in the Fengcheng Oilfield distributed predominantly in river channels or shoal microfacies with development of braided river depositions. Sparsely distributed internal in-terlayers may affect development of steam chamber and oil drainage. By using the typical heterogeneous model of the Zhong-32 Block as an example,impacts of positions,configurations and physical properties of such interlayers on SAGD have been reviewed through numerical simulation. Research results show interlayers between injector and producer with distance from producer less than 2 m,with lengths over 100 m,with thickness over 0. 5 m,or with permeability below 100×10-3μm2 may significantly affect performances of horizontal wells. In addition,interlayers above steam injectors with the distance from the injector less than 3m,with lengths over 100 m,with thickness over 1m,or with permeability below 100×10-3μm2 may significantly affect development velocities and patterns of steam chambers. In accordance with above properties,standards for classification of such interlayers have been clarified. Furthermore,wells with SAGD in the Fengcheng Oilfield can be classified into four categories. Relevant research results may provide valuable references to stipulate necessary countermeasures to enhance development perform-ances.关键词
