水平井压裂技术在低渗透油田开发中的研究与应用

吉林油田4.6×108 t探明未动用储量中,低渗透油藏超过90%,但产量普遍较低,为改变低渗透油藏"多井低产"的局面,开展低渗透油藏水平井开发试验,目前在新木油田庙130-4区块采取水平井整体开发的方式,有效地通过水平井分段压裂配套技术提高单井产能,产量为同区块直井产量的2～3倍,通过试验解决了类似储层单井产量低、开发效果差的问题.

RESEARCH AND APPLICATION FOR HORIZONTAL FRACTURING TECHNOLOGY IN THE DEVELOPMENT OF LOW-PERMEABILITY OILFIELD

The amount of low permeable sublayer of the reservoir in Petrol Jilin is more than 90% in 0.46 billion ton of the unexplored resource,but the output is generally low,for improving the state of the "well more produce low" in low permeable sublayer of the reservoir and developing exploitation attempt of the low permeable sublayer of the reservoir,the block 130-4 of Xinmu Field adopts the entire mode of the horizontal well to effectively improve the produce of the single well by the mating technology of horizontal well sectionalized fracturing, and than the produce is two or three times than the straight well in the same block,so the same problem of the "well more, produce low" is resolved by the attempt.
