Using automatic throwing gun device in try combined oil test technologies of TCP+APR can reduce risk for hoisting up pipe and workload, while, accident factors of liquid column pressure entering shot hole gun ahead, and shot hole jam after perforation will led to failure of lost gun, also, impact produced on condition of perforation with over 200m of shot hole guns and force on tube pipe when losing guns influence normal work of packers and pressure gauges. Through risk analysis and process improvement, device of automatically lost guns has been applied in the M-2 oil well operation successfully, and its test is successful. ©, 2015, Well Testing.

Productivity prediction equation for oil formation Fuyu in Chaganhu area is derived based on combination of some static information including logging data etc. and well test results. It avoids the limitation of predicting the early productivity only by logging data alone, and plays a role as a guide to well testing and exploration and development of the field.

As the new development block for the Dongping gas field, it is urgent to understand the production capacity of gas well and the connectivity of the well by the well testing to provide the basis for formulating the development project. At present in the gas field, production capacity test is mainly used of modified isochronal well test, testing for multi well is mainly utilized interference well testing, both of them are independent. Through integrated application of deliverability testing and Interference well testing to #1 well, the qualified deliverability testing data is not only acquired, but also the interference well testing data of adjacent wells are obtained. Compared with the traditional testing method, the integrated testing can carry out the interference test through testing of multiple switch interference pulse generated by the modified isochronal well test which has the characteristics of short test period, high construction efficiency, and high admission data to provide a new thought in the well testing of Dongping gas field. © 2016, Well Testing.

After years of development, drainage gas recovery technology for gas wells of producing water has made a great progress, but at present, there are problems of high operation cost, high risk, low efficiency, the frequent on-site operation and low ultimate recovery. In order to improve the recovery efficiency, to realize the purpose of long-term development for single well, it is necessary to make research and testing work for the mechanism and technology of the down-hole vortex drainage gas recovery mechanism, analysis and calculation software, eddy current equipment and supporting tools, pipe string structure design, so as to provide new ideas and methods for drainage gas recovery technology. ©, 2015, Well Testing.

Around handling methods to test fluid, typical burner type is listed for combustion process. Focusing on the core factors affecting test of crude oil burner combustion efficiency, four types of spray nozzles structure and characteristics that are the pressure atomization, swirl atomizing, pneumatic nebulization and bubble atomizing are analyzed, and field application of the process control, the ignition system back pressure, water spray, spray nozzle, atomization air supply, noise and radiation, heavy oil combustion of burner is discussed. According to the problems existing in the field application, a suggestion of search and development of a new generation of an-hydrous efficient test burner is proposed. © 2015, Well Testing.

The test to high deviated wells has bigger difference compared with the vertical Wells. During well test in high Angle Wells, problems of leakage of packer and not to be opened of N valve and circulating valve under design pressure are often encountered. Taking Pakistan M-2 inclined well as an example, through analyzing the force to the test tool in the inclined section, precisely calculation to filling nitrogen pressure value of N valve and circulating valve, and corresponding adjust of the test design and the operation, a much high success rate of test for the high deviated wells can be got as the vertical wells. ©, 2015, Well Testing.
