微波在油气开发中的应用

APPLICATION OF MICROWAVE TO THE EXPLOITATION OF OIL AND GAS

论述了微波的工作原理及其在油气开发中的实际应用。研究结果表明，微波开采稠油可提高油井产量1～4倍，并且不受油藏深度的限制；微波脱蜡可使清蜡时间由45min缩短到7min；与常规方法相比较，用微波对原油破乳能使脱水率提高16．7％～45．6％，并对聚合物驱的原油乳状液脱水具有明显效果；微波催化法分解天然气中的H2S，其分解率可达91．2％，能同时得到H2和S两种产物。微波用于油气开发，具有工艺过程简单、效率高、易于控制等特点。讨论了利用微波防止和脱除天然气开采中形成的水合物以及对堵塞地层的聚合物进行解堵的可能性。微波在油气开发中是一项具有发展前途的新技术。

This paper discusses the principle of microwave action and its application to the exploitation of oil and gas. The study showsthat the application of microwave can increase the yield of heavy crude oil by 1-4 times with no restriction to the depth of oilbearing reservoir; shorten the dewaxing period from 45 to 7min; raise dewatering efficiency by 16. 7%-45. 7% with anobvious effect in dewartering of crude oil emulsion flooded by polymer. In natural gas, 91. 2% H2S can be decomposed into H2and S by microwave. This paper also discusses the possibilities of preventing and removing hydrate formed in natural gasexploitation, and the possibility in decomposing polymer plugging reservoir. The study indicates that this technique is simple,highly efficient and easy to control in the development of oil and gas.
