气侵检测仪的研制与应用

Development and application of cas cut detector.

基于气体侵入井眼后按气液两相流型分布的原理 ,利用声波可以早期检测到气侵。文章对气侵进行了深入研究 ,研制了声波气侵检测仪 ,做到了生产过程中早期气侵检测 ,以避免井喷的发生 ,并及时发现油气层。

Based on the theory of two-phase flow pattern of gas and liquid, gas cut change can be detected with acoustic wave after gas flowing into wellbore. A gas cut detector is developed according to acoustic wave behavior through the research of the characteristics of gas cut change. In the process of drilling, the device can be employed to detect the change of gas cut so early that well blowout can be avoided and target layer can be found in time.
