准噶尔盆地低渗油藏地层测试技术研究

低渗储层的流体渗流具有明显的非达西渗流特性，在试油过程中，即使地层没有受到污染，流体也需要克服一定的阻力之后才能开始流动。因此，对于低渗油气藏的试油，不仅准确求取产能难度大，而且获取稳定的地层压力和储层参数更是十分困难。通过有针对性的测试工艺技术研究，采用合理分配测试时间方案、积极推广分层跨隔测试技术、利用测试技术进行压裂效果评价等，圆满地解决了低渗透储层试油测试中获取资料困难的问题。

TEST TECHNOLOGY STUDY OF LOW PERMEABILITY RESERVOIR IN JUNGGAR BASIN

Fluid flow of low permeability reservoir has obvious non Darcy flow characteristic.The fluid will not flow until the formation fluid overcomes certain actuating pressure gradient in the process of test,provided the reservoir is not polluted.As a result,obtaining precise fluid properties and quantity is difficult.Getting stable formation pressure and reservoir properties are more difficult.Through the test technology research,reasonable time plan of test is adopted,stratification straddle test technology is popularized positively and the fracture effect is evaluated by test technology.The difficulty of getting data during the process of testing low permeability reservoir is solved perfectly.
