摘要
L油田D区块应用常规压裂工艺措施效果逐年变差,为了提升区块动用程度,开展了整体缝网压裂试验。根据D区块储层地质特征,依托地质—工程一体化技术思路,从整体缝网压裂工艺设计出发,通过平面上单井优选井点控制砂体,纵向上优选层位实现立体改造。D区块整体缝网压裂投产后,措施初期平均单井日增液量为14.2t、日增油量为8.8t,压裂效果显著。该研究为外围油田低效开发区块增产提供了有效的技术手段。
The effect of conventional fracturing technology in Block D of L Oilfield becomes worse year by year.In order to improve the producing degree of the block,the integrated fracture network fracturing test has been carried out.According to the geological characteristics of the reservoir in Block D,and relying on the idea of integrated engineering and geological technology,the layer was optimized longitudinally to realize the three-dimensional transformation by designing an integrated fracture network fracturing and optimizing the well points for a single well on the plane to control sand body.After the integrated fracture network fracturing and production in Block D,the average daily fluid increment of single well is 14.2 t,and the daily oil increment is 8.8 t at initial stage,with remarkable fracturing effect.The study has provided an effective technical means for increasing production in low efficiency development blocks of peripheral oilfields.
