In the light of test wells with pump, the integrated technology of perforating, oil production and testing is taken, which can reduce working procedure, avoid pollution of drilling fluid to the formation effectively, save the operation cost, improve the work efficiency of the oil well. Taking a slow step method for lowering down or hoisting up pressure gauge, the operation is safe and reliable to get the significant economic benefits, which has broad application prospects for the sucker rod pump test technology. © 2016, The Editorial Department of Well Testing.

Field practices have shown that hydraulic particles as plugging agent, satisfy the need for permanent plugging of formation. Ultra-fine particle cement plays an important role in sealing and plugging formations of medium permeability. To seal and plug formations of low permeability and satisfy other special needs, a nano-meter hydraulic particle plugging agent was developed. This plugging agent has particle sizes of less than 1μm, with average particle size of less than 400 nm, and ratio of particles finer than 100 nm exceeding 21%. It is made by a high energy nano impact mill. The plugging agent is easy to disperse in water. Slurries treated with this plugging agent expand after solidification without the need for expansion agent, and have adjustable thickening time. The plugging agent has satisfactory compressive strength and low air permeability. It has been successfully used in an exploration well of five-interval in the 3rd structure, Nanpu, Jidong Oilfield.
