摘　　要：新沟嘴组低渗透油藏早期大多采取多层小规模笼统合压,储层平面及纵向改造极不充分,整体动用程度较低。优选老新油田,通过统计分析井温测试等动静态资料,精细描述剩余油分布规律,在注采井网优化的基础上,借助先进的压裂工艺,对动用不充分的储层实施针对性改造,取得了一定成果,同时提出了低渗透油藏高含水开发阶段“细分层全支撑压裂工艺”提液增油的新思路。In the early stage,multi-layer and small-scale general fracturing combination is adopted in most low-permeability reservoirs in Xingouzui Formation.The horizontal and vertical transformation of reservoirs is not enough,and the overall utilization degree is low.Taking Laoxin Oilfield as an example,this paper describes in detail the distribution law of remaining oil by analyzing the static and dynamic data such as borehole temperature test.On the basis of the optimization of injection-production well pattern and with the help of advanced fracturing technology,some achievements are made in the targeted transformation of insufficiently used reservoirs.At the same time,a new idea is put forward on fluid extraction and oil increase by separate minelayer+full support fracturing process in the high water cut development stage of low permeability reservoirs.
