Abstract

Combined perforation and sand-control technique is a new technique combining the perforation and sand control which are performed in one operation. This technique will simplify the performance, save the operating cost, reduce the formation damage and improve the well productivity. With this technique, there is no residue in the wellbore, thus providing favorable conditions for later treatments to the oil wells. It was developed by Drilling and Oil Production Technology Research Institute of Liaohe Oilfield Company, PetroChina in 1996. In-door research, physical simulation, the testing of various physical parameters, the development and design of complex perforation charges and guns, more than 1000 single target experiments and 7 times of full gun experiments were performed during the developing period. All technical specifications meet the requirements of the design. Field tests have been preformed since October 1999. By the end of January 2002, 24 well/times tests have been carried out and good results were achieved. The tests show that it is a very effective sand-control method in oil wells.
