疏松砂岩油藏压力脉冲解堵防砂技术研究
|
摘要
胜利油田在勘探开发过程中,疏松砂岩油藏受到钻井泥浆、固井水泥、射孔、入井液等固相颗粒堵塞,污染不可避免,防砂后产能降低,影响储量的探明和开发效果。常规酸化后产生二次污染,还对环保造成压力。因此,有必要深入研究分析地层堵塞机理,形成一套用于疏松砂岩油藏物理解堵的防砂新工艺。
为解决上述问题,本文作者在借鉴相关研究成果的基础上,加强合作交流,深入研究压力脉冲解堵新技术,同时配套防砂新工艺,形成一套完整的压力脉冲解堵防砂新技术体系。本论文主要进行了油井固相颗粒污染原因分析,压力脉冲传播理论数学建模,开展流体介质及液气混合介质对压力脉冲的影响实验,研制了压力脉冲发生器,设计了施工工艺和优化了解堵参数,研究进行井壁稳定性,配套了挤压充填防砂、压裂防砂工艺技术,进行了3个井次的现场实施,效果明显。
研究配套和现场实施的成功,充分证明了该工艺技术是可行和有效的,还具有不动管柱施工,节约成本等优点,是一种比较理想的解堵防砂新手段。
The deliverability will decrease after operation of sand control , and affect that reserve volume has verified and development effect because unconsolidated sand reserve are plugged off and polluted by the solid phase particles of drilling mud、well cement、perforation action、entering well liquid and so on . The second pollution will be produced and impacted on environmental protection after conventional acidizing. We should study and analysis the formation plugging mechanism consciouslyform a suite new technology with physical broken down and sand control for unconsolidated sand reserve.
To solve the problems, the Sand Control Technology Research Center of Shengli Oil Production Research Institute and Petroleum Engineering College of University of Petrolem co operate, begin to study the new technique of pressure pulse broken down deeply, and research new sand control technology with it ,form a complete system of pressure pulse broken down and sand control. The theme group has analysed the reasons of solid phase particle polluted in oil well, created a mathematic model about the pressure pulse broken down emission theory, done an experiment that show effection on pressre pluse by fluid medium or fluid and gas commixture medium , designed and manufactured pressure pulse generator device, designed process technology and optimized broken down parameters,studied stability of the well wall,researched squeezing and paking sand control technique,and completed one well experiment at well site and successed .
The success of study and experiment at well site proof enoughly that the technique is practicable and effective. The technique has advantage of operating without lifting pipe string and saving the cost,and is a perfect new method of broken down and sand control.
