Application of Cross Correlation Function Method in Locating Perforation Depth

Abstract

Abstract: Perforation depth correction technology for oil and gas wells is a prerequisite to ensure accurate perforation operations for oil and gas well completion. Perforating operations use the natural radioactive gamma correction method of oil and gas well reservoirs and the traditional depth correction method of tubing and casing joints. With the prolonged oil and gas production time, the downhole gamma radioactivity is weakened and the tubing and casing joints are damaged. The two signals of the depth calibration measurement are often obscured by downhole noise, and the effective signal characteristics are not obvious. Directly relying on the traditional amplitude identification method will bring about large perforation accuracy errors and even cause accidental perforation. It cannot meet the demand for precise deep perforation of thin reservoirs. Based on the calculation principle of the signal cross-correlation function method, the standard hoop signal and gamma signal are cross-correlated with the corresponding signals collected by the perforation depth calibration to suppress background noise, highlight the effective signal, and achieve the purpose of accurate perforation depth calibration. Field application shows that the method is simple in depth calibration technology, can meet the purpose of real-time calibration and perforation completion in one field operation, and has certain practical application value.

Key words: cross-correlation calculation, perforation calibration, perforation operation, oil and gas well completion, oil and gas reservoir development
