The Perforating Pressure Gauge is a high-precision tool used to measure and record the dynamic changes of downhole pressure during perforation operations in oil and gas wells. Within the millisecond period of the perforating bomb explosion, this device can completely record the generation, propagation and attenuation process of the pressure waveform at a high-speed sampling rate, providing crucial data support for evaluating the perforation effect, optimizing the completion design and analyzing the formation response near the wellbore.
Engineering Verification - Ensuring data reliability under extreme conditions
◆ Transient Pressure Calibration System
Different from the static calibration of conventional pressure gauges, our perforating pressure gauge adopts a three-level dynamic calibration system:
Basic Static Calibration– Perform multi-point calibration using a piston gauge in a temperature-controlled oil bath to establish fundamental accuracy.
Step Response Test– Generate millisecond-level pressure steps using a fast pressure relief valve to verify dynamic response characteristics.
Shock Wave Simulation Test– Simulate perforation pressure pulses in a dedicated test apparatus to validate the full system's recording capability under near-realistic shock conditions.
◆ Measured Performance Data
Based on statistical data from over 800 field operations, our Perforating Pressure Gauge demonstrate stable performance across the following key metrics:
Data Acquisition Success Rate – Achieved 99.3% in operations meeting design conditions.
High-Temperature Stability – Zero-point drift less than 0.03% FS/°C after continuous operation for 24 hours at 150°C.
Vibration and Shock Resistance – Passed 50 g, 11 ms half-sine wave shock testing.

Application Value & Data Analysis
◆ Key Application Scenarios
Perforation Efficiency Evaluation–Quantitatively assess the quality and cleanliness of perforation tunnels by analyzing pressure rise time, peak pressure, and pressure decay curves.
Underbalanced Design Verification–Accurately measure wellbore pressure at the instant of perforation to validate whether underbalanced design achieves intended effects and optimize underbalanced pressure values.
Downhole Anomaly Diagnosis–Identify abnormal fluctuations in pressure curves to assist in diagnosing issues such as partial perforation, premature firing, casing damage, etc.
Fracturing Design Input–Recorded pressure data provides critical reference for breakdown pressure and operation pressure design in subsequent fracturing operations.
