///In view of Daqing peripheral thin sand shale interbed, the authors analyze the small layer of low producing degree of the impact factors, through laboratory tests and field tests, proposed conditions do not have the stress of occlusion can choose barrier by rock shelter effect, and also expounded by logging selection criteria and process shale barrier control. The application results show that fracturing technology compartment optimization, card segment is divided, perforation and optimization of construction parameters by selection criteria for shale barrier, fracturing a high success rate, a small layer of high use. This is a guide to cost effective development of the external thin interbed of low permeability instructive.
