摘要
白马区块常压储层地质构造复杂和储层低品位化导致成本与效益开发的矛盾突出。为此,在分析区块地质特点和技术难点的基础上,通过优化设计密切割+限流压裂+投球暂堵+连续加砂的缝控有效体积压裂新工艺,初步形成适用于白马常压储层的分段压裂新技术,现场试验结果表明,压裂后测试产量提升明显。
The structural complexity and low grade of reservoirs under the normal pressure in the Baima block result in the conflict between cost and development effectiveness.Therefore,based on the analysis of the geological characteristics and technical difficulties of the Baima block,a new technology for the effective fracture-controlled volume fracturing has been firstly established for the staged fracturing in the block by the optimized design of high intensity of perforations,flow restriction,diversion by landing balls and continuous proppant volume.The test results show that the production rise is obvious after fracturing.
