摘要

基于前人的研究并结合超低渗油藏10年的开发实践,应用聚类分析法和灰色关联法,建立了包括优选评价参数、确定评价参数权重、划分油藏开发阶段、确定分类系数4个方面10项评价参数的超低渗油藏井网适应性定量评价方法。应用该方法对鄂尔多斯盆地三叠系长6、长8共13个主力典型超低渗油藏开展了井网适应性评价,得到3点基本认识：①超低渗I类油藏井网适应性整体较好,井网形式及井网参数都较为合理;②裂缝不发育油藏适合正方形反九点井网,裂缝较发育油藏适合菱形反九点井网,裂缝发育油藏适合矩形井网;③超低渗Ⅱ类、Ⅲ类油藏需要在坚持井网形式确定原则的基础上,进一步优化排距,提高该类油藏开发水平。图9表4参20

Abstract

Based on the previous studies and development practice in recent 10 years, a quantitative evaluation method for the adaptability of well patterns to ultra-low permeability reservoirs was established using cluster analysis and gray correlation method, and it includes 10 evaluation parameters in the four aspects of optimal evaluation parameters, determination of weights for evaluation parameters, development stage division, and determination of classification coefficients. This evaluation method was used to evaluate the well pattern adaptability of 13 main ultra-low permeability reservoirs in Triassic Chang 6 and Chang 8 of Ordos Basin. Three basic understandings were obtained: Firstly, the well pattern for ultra-low permeability type-I reservoirs has generally good adaptability, with proper well pattern forms and well pattern parameters. Secondly, square inverted nine-spot well pattern is suitable for reservoirs with no fractures; rhombic inverted nine-spot injection pattern is suitable for reservoirs with some fractures; and rectangular well pattern is suitable for reservoirs with rich fractures. Thirdly, for the ultra-low permeability type-Ⅱ and type-Ⅲ reservoirs, with the principles of well pattern form determination, the row spacing needs to be optimized further to improve the level of development of such reservoirs.

Key words： ultra-low permeability oil reservoir; well pattern adaptability; comprehensive evaluation parameter; Ordos Basin; Triassic; Chang 6 Formation; Chang 8 Formation
