摘要
Abstract
The mechanism of deep penetration of radial well with hole-drilling in casing technology developed in recent years is to form a plurality of radial hole in reservoir through high pressure water jetting, which could enlarge the drainage area and reduce production pressure drop. This paper analyzes the technical principles of this technology, and then proves the mechanism with well and layer selection of test wells through technical applicability. On the basis of these, the radial hole design plan of two testing wells were proposed, and the on-site operation situation was illuminated from the aspect of field test preparation and construction techniques. The testing results showed that both wells site construction had met the requirement of the design and made the yield increasing effect at some certain degree, even though failed to achieve the anticipated capacity. It is thought that the sand blocking resulted from debris flow-back difficulties is the key reason for increase of output not enough during the radial water jetting process.关键词
