CALTEC已开发出一套利用高压井能量采提高低压井产量的油井混合开采（WELLCOM）系统，该系统不仅能提高低压井的产量与采收率、而且有助于低压流体的输送。这种廉价又简便的系统在低油价下对边际油田的开采具有十分重要的意义。本文介绍了该系统的工作原理及其目前的现场应用情况。 CALTEC has developed a WELLCOM system that utilizes high-pressure well energy to raise the productivity of low-pressure wells. This system not only increases the productivity and recovery of low-pressure wells, but also contributes to the delivery of low-pressure fluids. This cheap and easy system is of great importance to the exploitation of marginal oil fields at low oil prices. This article describes the working principle of the system and its current field application.
