The fracturing of highpermeabilityzone is a vital breakthrough of hydraulic fracturing. We need to pretest the production response ahead of the tip screen-out fracturing design.
高渗透层压裂技术是水力压裂的一个重要突破,在进行高渗透压裂设计时需对方案的增产效果进行预测。

For highpermeability and loose sand in bohai, these links are composed of wire wrapped screen, gravel packing zone, perf, skin and near wellbore undisturbed formation.
具体到渤海高渗透疏松砂岩,这些环节包括绕丝筛管、砾石充填层、射孔孔眼、压实带及近井原状地层。

Near the décollement structure surface, at the bottom of the Cambrian and the top of the Archean, developed an interjacent fractured zone which shows high porosity and high permeability.
