塔里木油田轮古西奥陶系碳酸盐岩油藏埋藏深,油藏储集体形态各异,油水关系千差万别,导致开发难度大;碳酸盐岩基质基本没有渗流能力,裂隙和溶洞是主要的储集空间和渗流通道。针对这种情况,提出“一井一策”方针,对于治理注水替油效果差的裂隙型油藏,创造性地提出高压注水工艺,通过某井的6轮次高压注水试验,取得了很好的开发效果,对于开发类似的油藏起到了借鉴和指导意义。
The Late Oligoceceous Ordovician carbonate reservoirs in the Tarim Oilfield are buried deep and have various reservoir reservoirs with different oil-water relations, which makes it difficult to exploit the carbonate reservoirs. There is basically no seepage capacity in the carbonate matrix, and fractures and caves are the main reservoirs Set space and seepage channels. In response to this situation, a “one well and one policy” approach was proposed. For the treatment of fractured reservoirs with poor water and oil displacement effects, a high pressure water injection process was creatively proposed. Through six rounds of high pressure water injection tests in a well, Good development results, for the development of similar reservoirs played a guiding role and reference.
