美国芝加哥的天然气研究所设在得克萨斯州圣安东尼奥的西南研究基地,研制成一种井下彩色电视系统。这种系统是为开采泥盆系页岩和其它低渗透率地层的天然气设计的。 这种系统摄象机正下方的一个反射镜可由地面控制装置转动,以便很仔细地观察井壁。当井液进入井筒时,就能真切地看到从井壁液体逸出的气泡。采用这种系统有助于在泥盆系页岩井中选定最佳的完井层位。 据称,这种系统摄象机分辨彩色的能力很高,有利于提高图象解释的正确性。除了能观
The Institute of Natural Gas in Chicago, USA, is based in the southwestern research base of San Antonio, Texas, to develop a downhole color television system. This system is designed for natural gas exploration in Devonian shales and other low-permeability formations. A mirror just below this system camera can be rotated by the ground controls to allow careful observation of the borehole wall. As the well fluid enters the wellbore, the bubbles that escape from the wellbore liquid are truly visible. Using this system helps to select the best completion horizon in Devonian shale wells. Allegedly, this system camera capable of distinguishing color is high, help to improve the correctness of the image interpretation. In addition to the concept
