摘要
海塔盆地低孔、低渗复杂储层压裂改造施工成功率低，存在储层动用程度低和压裂改造效果差的问题。研究应用海塔盆地低渗透复杂类型储层压裂增产改造工艺，实现了高停泵压力梯度储层现场快速诊断技术，建立了砂泥薄互储层的隔层遮挡标准，形成了高含泥储层压裂施工参数优化方法。通过室内评价及现场应用，一次施工成功率由2008年的50．0％上升到2011年的92％，有效改善了高含泥储层的压裂施工效果。
In light of the issues of the low success rate in the fracturing treatment of complex reservoirs with low porosity and permeability and moreover the low developed degree of the reservoirs and the poorer effects of the operation in Haita Basin, the fracturing treatment and production-enhancing technology for the above low permeability and complex reservoirs are studied and then applied, and furthermore the quick in-situ diagnosing technique is realized for the reservoirs with highumpoff pressure gradient, the standards for the barrier restraint of sandy muddy thin interbeds are established, so the parameter optimizing method for the fracturing treatment of high mud-bearing is determined. Through the indoor evaluation and field application, the first-treatment success rate was rised from 50. 0% （ Year 2008 ） to 92% （ Year 2011 ）, the treatment results were effectively improved for the high mud-bearing reservoirs.
