Oil Perforation Bomb Detonation Wave Superposition And Interference

With the development of economic globalization, more and more oil development has been paying attention at home and abroad, and for oil development in terms of:oil exploration and development of the main form of perforated completion. In recent years, hydraulic perforation, laser perforation technology, such as the development of new types of perforating the oil fields at home and abroad to obtain significant results, but because of its operating cycle length, higher investment costs and drawbacks have not yet gained in the oil perforation promote the use of large area, while the use of blasting techniques to open reservoir, with its fast, efficient, inexpensive, operating results are obvious and so occupy the important position of perforating technology.As oil exploration and development of the continuous deepening of increasingly complex formation conditions and the well operating conditions, makes the requirements of blasting technology has increased, at present, our study is that oil is at the core of the bullet perforating blasting technology, which the use of oil perforation shells exploded high temperatures generated in the process carried out high-speed jet, so that in an extremely short period of time within the wellbore environment and formation environment communicate with each other to form an effective flow of the oil channel.This article aims to catapult the oil flow of the process of perforation depth analysis as well as perforation of oil after the bomb blast detonation wave superposition and interference of the jet center impact studies. Propose a solution targeted to within a short period of time wellbore environment and formation environment communicate with each other to form an effective and accurate flow of oil, and enhance the efficiency of perforation.Our main research contents include:1, detonation wave formation and jet theory research.2. The use of dynamic finite element method, two rounds of oil perforation process of the ejection flow modeling, solving, and results analysis. Analysis of oil Perforator blasting each other in the process of detonation wave superposition and interference. Oil Perforator Perforator order after the explosion in the formation of detonation wave, detonation wave is a perforating gun to the main external load, it is time and space of multi-parameter function, under the present conditions it is difficult to detect the passage of time and space curves, so the use of the theory of effective simulation of detonation detonation wave model becomes critical, and then right between the detonation wave superposition, interference numerical analysis. 3. The above analysis of the results analyzed and discussed to identify due to detonation wave superposition and interference impact on the jet center, on this basis, the requirements of that set perforation Center Method of amendment, thereby enhancing the efficiency of perforation.
