The oil and gas reservoir can be found and correctly evaluated in time, and the whole process of oil and gas exploration and development can be served. The construction process includes setting the test tool through oil pipe to the interval, setting the packer to seal, isolating the slurry/perforating fluid and other intervals from the test interval, and opening the underground test valve to make the stratum fluid flow into the pipe string to the ground. The well can be opened and closed for many times, the well is opened to flow to obtain the yield, the well is closed to measure the pressure to obtain the pressure data, and high-pressure sampling can be carried out at the same time.
The current well completion formation testing process is mainly as follows:
1. after the oil well is completed, a perforating gun is carried by an oil pipe, and a hole is perforated in an oil layer to open an oil layer channel. A schematic perforation is shown in figure 1.
2. The perforating string is put in again, the string with the formation testing tool is put in again, and the string is controlled by ground auxiliary equipment to form a temporary production system, so that the jetted oil layer is sampled, pressure-tested and the like, and the yield, the pressure, the temperature and the samples of the oil layer are directly recorded.
The mainstream formation testing tools today are primarily MFE and APR.

The MFE testing tool realizes the downhole opening and closing by lifting and lowering the oil pipe. When the tool is put into the well, the testing valve is in a closed state, after the preset depth of the test is reached, the packer is set, gravity is applied through the pipe column, the pipe column instantaneously drops by 25.4mm after a period of time delay, the testing valve is opened, and the well mouth reaction is the vibration of the pipe column. And lifting the pipe column to slightly exceed the free point, automatically shifting the position of the position shifting mechanism, and then lowering the pipe column to close the test valve. The pipe string is repeatedly lifted and lowered in such a way, and the test valve can be opened and closed for multiple times. The MFE test tool string mainly comprises a multi-flow tester (MFE), a hydraulic locking joint, a safety joint, a telescopic joint, a pressure gauge support cylinder, a TR time-adjusting jar, a packer and the like.
2) APR testing tool
The APR full-bore tester is an annular pressure type test tool. And under the condition that the test string is not moved, the well is opened and closed for multiple times by utilizing the application and release of the control ring control pressure. The APR testing system mainly comprises an LPR-N testing valve, an RD safety circulating valve, a hydraulic circulating valve, a BJ jar, an RTTS safety joint, an RTTS packer, a full-bore pressure gauge support cylinder and the like.
The LPR-N test valve is filled with high-purity nitrogen with designed pressure in advance on the ground, the ball valve is located at a closed position, after the tool is lowered to a preset position and the packer is sealed, preset pressure is applied to the annular space, the pressure is transmitted to the power mandrel to enable the power mandrel to move downwards, the power arm is driven to enable the ball valve to rotate, and well opening is achieved. When the well needs to be shut in, the annular pressure is released, and under the action of the nitrogen pressure, the power mandrel moves upwards to drive the power arm, so that the ball valve is closed. The repeated operation can realize the repeated well opening and closing.
