摘　　要：胡154区是胡尖山油田主力油藏之一,开发层位长4+5,属三叠系岩性油藏。该区为近几年措施的主力区块,储层厚度大、物性差,隔夹层和微裂缝发育,由于储层渗透率低,地层向裂缝渗流起控制作用,采用常规压裂增产能力有限,有效期短。因此急需转变改造思路,结合"体积压裂"理念,实现人工裂缝于油藏最大的接触面积和体积,达到充分释放油气的目的,极大的提高单井产能。The target layer, Chang4＋5, is located in Hu154 district which is one of the main Triassic lithologic reservoirs in Hujianshan oil field. In the past few years, many measures have been taken in the area, however, the reservoir property is poor even the thickness is favorable, menwhile, the interlayers and the micro cracks are well developed, thus the mech- anism of flow is mainly controlled by the cracks which reduce the effect of conventional frac- turing treatment resulting shorter active period.There is an urgent need to change the ideas, and it is necessary to use the＂volume fracturing＂ theory, enhance the fracture volume to pro-vide a better way for the hydrocarbon release and greatly improve the productivity of single well.
