摘要(Abstract)：

海拉尔油田储层渗透率低、岩性复杂,薄差层发育,以往采用大段合层压裂,因压裂时纵向多层改造不彻底而影响压裂效果。通过精细的岩性识别并利用测井、岩石力学参数关系及动-静态岩石力学参数关系,建立了多薄差层地质模型,提高了弹性模量与地应力解释精度。在岩石力学参数研究的基础上,应用三维有限元数值模拟得到了裂缝垂向扩展规律,建立了薄差层细分多层压裂标准。形成了计算软件,输出的分层曲线可为该区块薄差层分层改造优化设计提供依据。
Hailer Oilfield is characterized by low permeability,complex lithology,multiple sets of sedimentary and volcanic rocks etc.,and moreover the thin and poor layers are well developed,so the previous large segment of commingled layer fracturing resulted in the incomplete longitudinal multi-layer fracturing stimulation,the fractured effects are directly influenced.With the help of fine lithology identification,parameters relations between the well logging and rock mechanics and furthermore the parameters relations between the dynamic and static rock mechanics,the geological model is established for the thin and poor layers,finally the interpretation precision between the elastic modulus and geostress is improved.On the basis of the researches of the rock mechanic parameter relations and by means of 3D finite element numerical simulation,the vertical crack propagation law is achieved;the standards and criteria for the s thin and poor subdivided multilayer fracturing are established.And moreover the output layer-dividing curves from the developed software can provide the evidences for the optimized design of the thin and poor separate layer fracturing of the block.
