Composite perforator has got great technical progress recently,but there has not been any effective surface test device of it available as yet,so that sometimes the quality of composite perforator is out of effective control.

Introduced are quality control factors in the process of the fracture perforators production and some new testing methods influencing on the perforators quality.

Introduced are a simulating device of fracture perforators and a dynamic pressure testing method.

Movement mechanism experiment of top control fluid in compound perforation;

By doing some optimizations such as optimizing technology,optimizing the detonator amount of compound perforation,selecting phase angle and improving the pattern of placing holes,a perforatio.

Deep penetration compound perforation technology joins organically the perforation technology and high-energy gas fracturing technology,which is a new perforation tec.

Experimental verification of numerical analysis accuracy of composite perforation;

According to the conditions of the bad reservoir physics character of Jilin Yingtuo oilfield,all the new perforated and completed wells must being hydrafrac to increase production and some bottom hole water of them having developed much,producing water after hydrafrac and high exploitation expense,hang composite perforation tech is utilized to be well completion to increase production and effect.

built-in style,oversleeve-style,symmetry style and hanging style perforators,a method of optimizing effective composite perforation by correct determining peak value of pressure and amount of gunpowder,under the precondition of operation safety,according to the hole structure and formation damage is proposed.

Application of packer in fracture perforating;

A new projectile-filling device was developed to realize the fracture perforating under the condition of high foramen density.

During a fracture perforating operation, there are some events of spacer gun flexion.
