试井测试的优化研究——以旗胜49-1343为例

Rsearch on Optimization of Testing of Test Well——By Taking the Qisheng 49-1343 as An Example

延长油田属于典型的低渗透油田,油井投产时基本没有自喷能力,需要经过酸化、压裂等油气增产措施.百年油田面临着资源接替不足的窘境,注水开发是目前油田的重点工作,这需要运用压力测试手段落实油藏压力变化,分析储层渗流特征和渗流能力,评估储层能量和完善程度等.为确保压力测试资料的真实准确,就必须改进测试工艺,优化解释方法.只有这样,才能为开发方案的调整、增产增注措施的制定提供可靠的依据.

Yanchang Oilfield belongs to the typical low permeability oilfield,and the oil well has no natural flow ability when it is put into production. It needs to increase oil and gas production by acidizing and fracturing. The oil field of 100 years is facing the dilemma of lack of resources to replace,and water injection development is the current key work of oil field. It is necessary for us to use pressure testing to carry out reservoir pressure changes,analyze reservoir percolation characteristics and percolation capacity,and evaluate reservoir energy and degree of perfection and so on. In order to ensure the true and accurate data of pressure testing,it is necessary to improve the testing process and optimize the interpretation method. Only in this way can we provide a reliable basis for the adjustment of development plan and the formulation of measures for increasing production and increasing injection.
