摘要

尕斯库勒油田是柴达木盆地目前开发的主力油藏之一，作为有效动用新增地质储量、实现建产目标的有利区，该油田N₁—N¹₂油藏下盘南区储层分布井段长，油砂体平面分布连续性差，油水关系受岩性控制明显，给油藏开发带来了一定的困难。通过老井资料复查，结合钻井、试油试采资料，以地质、测井等学科方法开展储层地质特征综合研究，进而搞清油水关系，在“钻前评价、过程跟踪和深化认识”滚动开发实践中取得了较好的效果，对改善研究区和同类复杂岩性油藏的开发具有一定的指导意义。

Abstract

Gasikule oil field is one of the main oil reservoirs in the current development in Qaidam basin.As a favorable area of effectively producing newly geological reserves and achieving the goal of productivity construction,it presents some difficulties in reservoir development in the footwall south part of GasikuleN₁—N¹₂ oil reservoir for its long distribution of well sections,poor plane discontinuity of oil sand and oil-water relationship controlled by lithology.For many years,combined with drilling data and production test data,oil-water relationship has been further clarified through old well review by some scientific methods to develop comprehensive study on reservoir geological characterization,such as geological method and logging method,so that better profit is taken during the progressive development practice based on the strategy of pre-drilling evaluation,process tracking and understanding deepening.It is also instructive to improve the development effect of the study region and complex lithology reservoir.

Key words： Gasikule oilfield; N₁—N¹₂ oil reservoir; Standard level; Progressive development
